Collar drill bushing DIN 172 form B, bore 13.7 mm, length 16 mm, collar 26 mm, hardened steel

The 13.7 mm bore takes up the tool and the overall length of 16 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 26 mm at a height of 4.0 mm.

Benefits

• Bore 13.7 mm, ground and dimensionally accurate to DIN 172
• Outside diameter 22 mm for a press fit in the drill plate
• Collar 26 mm with 4.0 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 short 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.
