Cylindrical drill bush DIN 179 form B, bore 3.1 mm, length 8 mm, outside dia 6 mm

This drill bush guides tools of 3.1 mm diameter and keeps the drilling axis in position over the full length of 8 mm. The bore follows form B of DIN 179 and is therefore rounded on both sides.

Benefits

• Bore rounded on both sides to form B, so the bush can be fitted either way round
• Overall length of 8 mm in the short version of the range short, medium and long
• Guide bore of 3.1 mm to DIN 179 for the matching tool
• Dimensions to DIN 179, so existing bushes can be replaced size for size
• Outside diameter of 6 mm as a ground seat in the drill plate

Applications

• Fixed drill plates and hinged drilling jigs
• One-off and small batch production in mechanical engineering
• Drilling fitted holes on assemblies with a fixed hole position
• Inspection and marking templates in assembly

Standard and material

The bush is made to DIN 179 in form B, and the bore is rounded on both sides. The material is special case-hardening steel, hardened to 740 ± 80 HV 10 and ground.
