3 Point Groove
• Available from 6-300mm diameter
• Interchangeable with standard heads
• XTA, XTD, XTH, Superbore.
• Special forms, Radius, Ball contacts.
• Depth stops available for quick location.
• Annular grooves possible.
3 point head for Baker Hughes
Groove diameter and depth inspection again Baker Hughes, Belfast.
Dimension from end of bore to front of groove. This head measures a distance not a diameter. The anvils are used to set
the datum position. Hughes Tool, Texas.
3 point groove + large range. Reed Tool, Texas
Pins extended for Annular groove. Also useful if a boss
interrupts measurement of a blind bore
3 point head to measure Brake caliper. Anvil head for Delphi China.
Close-up showing measuring position
Thread head
• Use with all Digital systems• Metric, UN, Buttress, Acme, Trapezoidal, Ball screw and
non-standard forms available.• LH and RH• Effective (Functional), Pitch & Major measurement
• Calibrate from thread rings (Plain ring for Major Diameter)
• Rings marked with actual PD
• Very fast measurement of threads
2 point Thread head. Supplied into Bowers France.
3 point thread head for Pitch diameter.
• Note single thread form!Note single thread form for pitch diameter
Note single thread form for pitch diameter
Small 2 point thread head below M10 / 3/8” with slot width head.
Ballscrew thread heads. Originally for Thomson IBL but now to TRW, ZF Steering
3 point / 2 point spherical
• Use with any digital system
• 2 point available from 3mm, 3 point available from 6mm
• Ease of use for operator
• 2 point supplied spherical as standard above 6mm
• Allows for misalignment in bore
• Tool steel anvils with XT / BS. Superbore carbide above 50mm
• Very low wear
• Always use for deep hole measurement
3 point spherical for Electro-impact used on A380
http://www.electroimpact.com/
• All Electroimpact heads are used on the large machines drilling the A380 wings. The heads are used for automated inspection of every hole machined. The head shown is manufactured with a tapered cover plate this allows for mis-alignment of head when first entering the bore. Supplied in the region of 100 off via Fowler in the US.
Close-up spherical anvil on 35-50mm head
Internal Splines
• Use with any digital system.
• 2 point between pin most popular. Can also supply with carbide ball contact. 3 point also available with irregular spacing if necessary.
• Heads for Major and Minor dia. available.
• Calibrate from standard plain rings.
• NTN (Renault supplier) largest customer with over £100K
Order for NTN 2 point between ball dimension
2 point spline head with pins on BS. This head was pre unit construction of the anvils
Deep hole Pneumatic system• Maximum depth we can measure 15metres above
50mm diameter (Pneumatic system)• Accuracy +/-0.005mm at 15 metres depth.• 6 Bar air pressure required either from compressor
or factory air supply.• Usually 3 point but can supply 2 point, all with
spherical anvils• Maximum diameter so far supplied 400mm.
• Simple operation.• All heads should have guide sleeve• Not effected by temperature fluctuations
• Calibrated prior to assembly
Deep hole XT
• Maximum depth 2 metres above 20mm diameter• Can supply as 3 point or 2 point spherical• Use 500mm long extensions 20mm+
• Use 1000mm extensions 35mm +• Can be effected by temperature.• Require same depth in front of the bore being
measured as is calibrated assembled.• Not for use for high precision inspection
• Try to use in a temperature stabilised environment.

Large Diameter. Two of 4 special large diameter heads produced for R.J Tubular. Largest is 18.45” - 19.45” shown with 6-8mm head in
foreground
Rivet Height Gauge
40mm Cannon Rifle groove. The angle on the face is to allow the form to follow the groove around the helix. The nose piece unscrews to allow a camera to interchange for
visual inspection
Universal Gauge. Most popular modification is longer arms. Have produced up to 300mm. Special width depth stops , larger ball contacts
are also popular.
CBG. Most popular and Longer / shorter stems. Maximum depth we recommend is 2 meters above 50mm. RA adapters can also be supplied
for CBG with photograph to follow.
