2014 is still young and the fi rst issue of our new magazine is hot off the press! With our "Breaking News" twice a year, all you professionals in action will "know the drill". And that in the truest sense of the word: Information about drill bits and drilling, challenges from everyday practices and

interesting facts about construction.

In this trade fair edition the focus is, of course, on the International Hardware Fair in Cologne. In March we’ll be presenting a number of new products here such as the Bionic Pro SDS-plus hammer drill bit. More details on this can be found on pages 6-11. In addition there are many interesting topics:

We provide insights into our company, answer questions about safety and user protection and have subjected our SDS-plus 3-cutter, the Trijet, to a hardness test. This is what we concluded: Sometimes less is also more. But we do not want to give too much away. Read it for yourselves.

We hope that you enjoy the "Breaking News". And of course we’re always happy to hear your suggestions. For example via our Facebook page or at info@hellertools.com. Have fun browsing and reading!

When exactly the fi rst construction site in the world was completed, no one really knows any more. But the longest and also the oldest road construction site is located between Alaska and Argentina. As some areas have still not been fully developed or asphalted, the construction of the 30,000-kilometre-long Pan-American Highway has now been ongoing since 1925. Surely no construction worker will live long enough to witness both the start and the completion of this project.

Going even higher was the dream of the builders of the Burj Khalifa in Dubai. Construction on the huge skyscraper began in 2004 and in 2009 it reached a record high of

Because, being 3,250 meters in length, Terminal 3 there is the longest building in the world. For 1.8 billion euros, the steel and glass structure was built on 1.3 million square meters, according to the ideas of star architect Norman Foster. Also in China, is the building with the largest area: The New Century Global Centre in the Chinese sub-provincial city of Chengdu, completed in 2013 is the biggest building in the world, at 1.7 million square metres.

Records and competitions are as old as mankind. And in the building

WHAT MANY DON’T KNOWThe record for the most crooked tower in the world is not held by the land-mark in the Italian city of Pisa, but rather by a church tower built in 1450 in East Frisian Suurhusen. This record holder has a height of 27.37 metres and is at an angle of 5.19 degrees – right at the forefront of the category of non-intentionally incorrectly-built buildings in the Guinness Book of

World Records. Here, unfortunately, Heller drill bits were not yet available: Drill forger Jacob Heller from Schmalkalden was fi rst documented in a chronicle in 1583.

828 meters. Since then it has held the title of "the tallest building in the world". Overall, the construction costs of the project amoun-ted to 1.5 billion U.S. dollars. The most important criterion for professionals on the construction site: having a head for heights!

However, buildings don’t just stretch up high but also wide. And the construction workers at the Beijing airport had to be especially enthusiastic about movement.

QUALITY "MADE IN GERMANY“

JÖRG FROMMEYER, MANAGEMENT MARKETING, PRODUCTS, OPERATIONS: "Made in Germany" continues to be a

seal of quality that infl uences purchasing decisions as well as a simple and compelling summary of our high performance level. It is

not only in the export markets, with a share of sales of over 80 percent that our customers rely on values such as quality, safety, and success. There are 3 key factors that bring Heller products to their high level: Excellent raw materials, highly automated machinery, and staff with years of experience. "Made in Germany" is therefore also a challenge we have to set ourselves every day.

RAFIQ BANATWALA, OWNER OF NEXT GEN TOOLS: Essentially, "Made in Germany" stands for high product

quality. It does not matter whether it is drill bits, machines, tools or other products. The label stands for an advantage

that German products have over products from other European manufacturers. The user gets what they were promised: a reliable product. In addition, the durability of a product of German origin is guaranteed. Throughout the world, "Made in Germany" thus stands for trust and reliability.

MICHAEL KLEINE, MANAGER, MAC PANTHER GMBH: In an increasingly complex world, the desire

for simple guidance is becoming ever greater. The label "Made in Germany" helps people to fi nd products that promise a consistently high

quality. "Made in Germany" is also a promise that moral and ethical standards are being observed, e.g. with regards to occupational safety, wages and fair competition.

MARK ANDERSON, MANAGER AT AUSTRALIAN PRECAST PANEL SYSTEMS: In my view, the new Heller Trijet symbolizes everything that

"Made in Germany" stands for. Carbide drill bits from Germany are generally among the best in the world. But the new Heller Trijets are real "weapons" – that was the unanimous opinion of our team. During tests in our concrete panels with a thickness of up to 70 megapascals, poor quality is recognized immediately. The Trijet stands out prominently from the plethora of good drill bits: Fast, with less vibration and a long life. These are the properties that products "Made in Germany" must allow them-selves to be measured by.

There is lots of hard grafting, sweating and moaning. And the tone is often very harsh. "You’re a few uprights short of a fence!", they’ll say. But 5 minutes later it’s all forgotten again.

A hollow drill bit which sucks away the dust directly as soon as it forms in the drill hole. Not just when dust is transported from the hole: This is the Duster Expert. A conven-tional vacuum cleaner is simply connected to the hammer drill.

Dust emission is lar-gely prevented. This reduces health risks signifi cantly. This way users can drill and clean the hole in just one step.

The Duster Pro is an adapter that is connected to a vacuum cleaner. The dust transported from the hole is simply sucked away. The Duster Pro sticks to the wall by itself by vacuum. The dust protection can be used for a drilling diameter of up to 42 millimeters. This way the distribution of dust is effectively prevented.

The trend in the bathroom is moving toward ever harder tiles, both on the wall and on the fl oor. This stoneware presents one of the major challenges. According to Villeroy & Boch, there are hardly any effi cient solutions for drill bits and angle grinders.

This is increased further by the requirement to dry drill, so as not to leave any dirt or splashing water when renovating. And glazed, hard-burnt tiles also cause real diffi culties. The new Cera Expert series can remedy this.

LESS DUST,MORE HEALTHDUST FREE DRILLING – WORK EFFICIENTLY

A hollow drill bit which sucks away the dust directly as soon as it forms in the drill hole. Not just when dust is transported from the hole: This is the Duster Expert. A conven-tional vacuum cleaner is simply connected to the hammer drill.

Dust emission is lar-gely prevented. This reduces health risks signifi cantly. This way users can drill and clean the hole in just one step.

The Duster Pro is an adapter that is connected to a vacuum cleaner. The dust transported from the hole is simply sucked away. The Duster Pro sticks to the wall by itself by vacuum. The dust protection can be used for a drilling diameter of up to 42 millimeters. This way the distribution of dust is effectively prevented.

The trend in the bathroom is moving toward ever harder tiles, both on the wall and on the fl oor. This stoneware presents one of the major challenges. According to Villeroy & Boch, there are hardly any effi cient solutions for drill bits and angle grinders.

This is increased further by the requirement to dry drill, so as not to leave any dirt or splashing water when renovating. And glazed, hard-burnt tiles also cause real diffi culties. The new Cera Expert series can remedy this.

QUALITY "MADE IN GERMANY“

JÖRG FROMMEYER, MANAGEMENT MARKETING, PRODUCTS, OPERATIONS: "Made in Germany" continues to be a

seal of quality that infl uences purchasing decisions as well as a simple and compelling summary of our high performance level. It is

not only in the export markets, with a share of sales of over 80 percent that our customers rely on values such as quality, safety, and success. There are 3 key factors that bring Heller products to their high level: Excellent raw materials, highly automated machinery, and staff with years of experience. "Made in Germany" is therefore also a challenge we have to set ourselves every day.

RAFIQ BANATWALA, OWNER OF NEXT GEN TOOLS: Essentially, "Made in Germany" stands for high product

quality. It does not matter whether it is drill bits, machines, tools or other products. The label stands for an advantage

that German products have over products from other European manufacturers. The user gets what they were promised: a reliable product. In addition, the durability of a product of German origin is guaranteed. Throughout the world, "Made in Germany" thus stands for trust and reliability.

MICHAEL KLEINE, MANAGER, MAC PANTHER GMBH: In an increasingly complex world, the desire

for simple guidance is becoming ever greater. The label "Made in Germany" helps people to fi nd products that promise a consistently high

quality. "Made in Germany" is also a promise that moral and ethical standards are being observed, e.g. with regards to occupational safety, wages and fair competition.

MARK ANDERSON, MANAGER AT AUSTRALIAN PRECAST PANEL SYSTEMS: In my view, the new Heller Trijet symbolizes everything that

"Made in Germany" stands for. Carbide drill bits from Germany are generally among the best in the world. But the new Heller Trijets are real "weapons" – that was the unanimous opinion of our team. During tests in our concrete panels with a thickness of up to 70 megapascals, poor quality is recognized immediately. The Trijet stands out prominently from the plethora of good drill bits: Fast, with less vibration and a long life. These are the properties that products "Made in Germany" must allow them-selves to be measured by.

RELIABLE, EXCELLENT AND RECOGNIZED WORLDWIDE

THINGS CONSTRUCTION WORKERS DON‘T SAY

There is lots of hard grafting, sweating and moaning. And the tone is often very harsh. "You’re a few uprights short of a fence!", they’ll say. But 5 minutes later it’s all forgotten again. Breakfast is at 9am and lunch is at 12pm. There is discussion about politics and football, women and the boss.

But there are also quite a number of things that a construction worker would not say. Colleagues would react to these comments with great astonishment. Here are a few suggestions from the Breaking News editor:

If you have any other proposals and suggestions the Breaking News team would love to hear them. Just send them to promotion@hellertools.com

SAFETY FIRST

On construction sites the highest safety

requirements prevail. Bad tools lead to

inaccuracies and unprofessional results. This

endangers the safety – both of the user and

of the other employees. This is why Heller

sets top quality and control standards right

from the start of production.

QUALITY PROTECTS USERSProduct safety and user protection are top

priority in construction. Under the label "Quality for Professionals" Heller stands for convincing

product quality. The production of drill bits "Made in Germany" is certifi ed and externally monitored. The result: the highest security requirements with minimal tolerances. Special features include the high precision in the symmetrical alignment of the carbide tips, a special surface treatment and hardening, as well as the automatic straightening method for reducing the probability of breakage and vibration characteristics of the drill bit.

GOOD VIBRATIONSAs the fi rst European drill bit manufacturer Heller has had its products independently tested at Loughborough University – the leading institute for hand-arm vibration testing. The result: optimal effi ciency and minimal vibration. Anyone working a lot professionally with hammer drills or similar oscillators must reckon with the possible long-term health issues caused by increased "hand-arm vibration". The "EU Vibration Directive 2002/44/EC" aims to help here.

DISTINGUISHED AS SAFEProducts from Heller are also certifi ed by the "Prüfgemeinschaft Mauerbohrer e.V. (PGM)" (independent masonry drill bit testing association). Through monitoring and tests the PGM checks if drill bits have been correctly designed for use with approved anchors.

There are only a few authorized manufacturers who were distinguished by the PGM. Drill bits with

this symbol provide geometrically accurate holes for maximum grip and maximum safety.

CONCLUSION

3-cutter or 4-cutter? This question is the subject of much controversial

discussion among experts. Which drill bit has a higher transport volume,

which has a lower wear and which the lower vibration? The hardness test

with SDS-plus and SDS-max drill bits brings light into the darkness and

shows: Sometimes less is more. In addition to the Trijet from Heller,

4-cutters from the competition were tested.

2 DRILL BITS ARE SOMETHING ONLY FOR REALLY HARD BOYS

Specially hardened drill bits not only ensure longer life of the tools, but also prevent, for example, worse accidents happening due to a drill bit breaking. In order to minimize this hazard, Heller relies on a special surface treatment and hardening, as well as automatic straightening methods for reducing the probability of breakage and vibration characteristics of the drill bit.

"LATEST" FINDINGS FROM THE BUILDING SECTOR

3 FOAM AND SILICONE DISPLACE PRECISION

Circular holes and drill bits with low vibration reduce the use of foam and silicone. The precise alignment of the carbide ensures low tolerances in the radial run-out. In combination with the optimal helical shape, Heller drill bits cause less vibrations. This means construction professionals need to reach for the foam far less frequently.

1 A NAILED-ON SCREW HOLDS BETTER THAN A SCREWED-ON NAIL

The best option, however, is a perfect drill hole anchor connection. In addition, this ensures safety and prevents accidents in construction. No helmet can ultimately protect against montages falling apart or falling construction components. Heller products are certifi ed by the Prüfgemeinschaft Mauerbohrer e.V. for a safe drill hole anchor connection. Heller therefore offers maximum security for maximum success of the construction project.

WISDOM OF CONSTRUCTION

“SMALL” BRIDGE BUILDING GLITCH

Deviations of one or two centimetres often do not play a major role. But sometimes they can be decisive. This especially applies to bridge building. The best example: the city of Laufenberg. This is right on the border between Germany and Switzerland. That means: Part of the city is located in Germany, the other part belongs to the neighbouring country. In 2003 construction began of the Hochrheinbrücke, which would henceforth connect the two parts together. However, there was a small but crucial difference in height of 54 centimeters. The reason for this was a classic design fl aw: the two countries have a different height reference. While Germany's is related to the sea level of the North Sea, Switzerland’s is taken from the Mediterranean. After all errors had been eliminated, the insurance of a Swiss engineering company was liable for the damages.
