Frequently Bought Together
The 4.1 mm bore takes up the tool and the overall length of 12 mm provides a long guide. The case-hardening steel is hardened to 740 ± 80 HV 10 and ground, so the bore stays dimensionally accurate even after many machining cycles. The collar measures 11 mm at a height of 2.5 mm.
Benefits
- Bore 4.1 mm, ground and dimensionally accurate to DIN 172
- Collar 11 mm with 2.5 mm height for axial location
- Overall length 12 mm in the medium series
- Outside diameter 8 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
