Collar drill bushing DIN 172 form B, bore 36 mm, length 56 mm, collar 59 mm, hardened steel

With a bore of 36 mm and an overall length of 56 mm, this bushing keeps the tool on track inside the drilling jig. The collar of 59 mm diameter and 5.0 mm height bears on the drill plate and secures the bushing against axial slipping.

Benefits

• Ground guiding bore of 36 mm within the tolerances of DIN 172
• Press fit of 55 mm outside diameter in the holder of the jig
• All-round collar of 59 mm diameter and 5.0 mm height acting as a stop
• Guiding length of 56 mm, medium design
• Form B design of DIN 172 with the bore rounded on both sides, also for a reversed fit
• Hardened case-hardening steel at 740 ± 80 HV 10 with a ground surface

Technical data

Applications

It is used wherever holes of 36 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 B. In form B the bore is rounded on the opposite side as well. The bushing is made of hardened and ground case-hardening steel with a hardness of 740 ± 80 HV 10.
