Collar drill bushing DIN 172 form B, bore 10.7 mm, length 12 mm, collar 22 mm, hardened steel

Designed for tools of 10.7 mm diameter, this bushing seats in the fixture with an outside diameter of 18 mm. The overall length of 12 mm in the short series sets the guiding length, and the 22 mm collar secures the bushing axially.

Benefits

• Bore 10.7 mm, ground and dimensionally accurate to DIN 172
• Overall length 12 mm in the short series
• Outside diameter 18 mm for a press fit in the drill plate
• Collar 22 mm with 4.0 mm height for axial location
• Case-hardening steel hardened to 740 ± 80 HV 10
• Form B to DIN 172 with the bore rounded on both sides, so the bushing can be used from either end

Applications

The bushing is used in drilling jigs in tool and fixture making, in series production and in repair work where holes have to be placed repeatably.
