Collar drill bushing DIN 172 form B, bore 13.9 mm, length 16 mm, collar 26 mm, hardened steel

With a ground bore of 13.9 mm this bushing holds the tool on position over a guiding section of 16 mm. The collar of 26 mm diameter and 4.0 mm height stops the bushing from travelling through the fixture while drilling.

Benefits

• Bore 13.9 mm, ground and dimensionally accurate to DIN 172
• Overall length 16 mm in the short series
• Outside diameter 22 mm for a press fit in the drill plate
• Collar 26 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.

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.
