Collar drill bushing DIN 172 form A, bore 38.5 mm, length 67 mm, collar 59 mm, hardened steel

The collar drill bushing with a 38.5 mm bore comes in the long series at 67 mm. Its case-hardening steel at 740 ± 80 HV 10 withstands contact with the cutting edge over large batches, and the 59 mm collar fixes its position.

Benefits

• Ground guiding bore of 38.5 mm within the tolerances of DIN 172
• All-round collar of 59 mm diameter and 5.0 mm height acting as a stop
• Press fit of 55 mm outside diameter in the holder of the jig
• Hardened case-hardening steel at 740 ± 80 HV 10 with a ground surface
• Guiding length of 67 mm, long design
• Form A design of DIN 172 with the bore rounded on one side, on the side of the collar

Applications

It is used wherever holes of 38.5 mm have to be produced without centre punching and without wandering, for example in jigs for series parts, in assembly gauges or in prototype work.

Standard and material

Dimensions and tolerances follow DIN 172 in form A. In form A the bore is rounded only on the side of the collar. The bushing is made of hardened and ground case-hardening steel with a hardness of 740 ± 80 HV 10.
