Collar drill bushing form B to DIN 172, bore 1 x 6 mm, collar 6 mm, case-hardening steel

Made for holes of 1 mm, this bushing guides the tool over 6 mm. The short series combines a press fit of 3 mm outside diameter with a 6 mm collar that holds the bushing in the plate.

Benefits

• Guiding length of 6 mm, short design
• Ground guiding bore of 1 mm within the tolerances of DIN 172
• All-round collar of 6 mm diameter and 2.0 mm height acting as a stop
• Press fit of 3 mm outside diameter in the holder of the jig
• Hardened case-hardening steel at 740 ± 80 HV 10 with a ground surface
• Form B design of DIN 172 with the bore rounded on both sides, also for a reversed fit

Technical data

Applications

It is typically fitted into the drill plates of jigs in mechanical engineering, contract manufacturing and mould making, where the same 1 mm hole is produced again and again in the same place.

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.
