Collar drill bushing DIN 172 form B, bore 6.2 mm, length 16 mm, collar 15 mm, hardened steel

Designed for tools of 6.2 mm diameter, this bushing seats in the fixture with an outside diameter of 12 mm. The overall length of 16 mm in the medium series sets the guiding length, and the 15 mm collar secures the bushing axially.

Benefits

• Bore 6.2 mm, ground and dimensionally accurate to DIN 172
• Outside diameter 12 mm for a press fit in the drill plate
• Collar 15 mm with 3.0 mm height for axial location
• Form B to DIN 172 with the bore rounded on both sides, so the bushing can be used from either end
• Overall length 16 mm in the medium series
• Case-hardening steel hardened to 740 ± 80 HV 10

Applications

It is used wherever holes have to be produced repeatedly in the same position, for example in fixture construction, assembly and gauge making.

Standard and material

The design complies with DIN 172 form B, in which the bore is rounded on both sides. The material is case-hardening steel, hardened to 740 ± 80 HV 10 and ground.
