Collar drill bushing DIN 172 form B, bore 8 mm, length 16 mm, collar 15 mm, hardened steel

Designed for tools of 8 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.

• Outside diameter 12 mm for a press fit in the drill plate
• Form B to DIN 172 with the bore rounded on both sides, so the bushing can be used from either end
• Case-hardening steel hardened to 740 ± 80 HV 10
