Cylindrical drill bush DIN 179 form B, bore 43 mm, length 30 mm, outside dia 62 mm, ground

A drill of 43 mm diameter runs guided through 30 mm of this bush and meets the hole at the intended point. The design follows DIN 179, form B, and the bore is rounded on both sides.

Benefits

• Guide bore of 43 mm to DIN 179 for the matching tool
• Outside diameter of 62 mm as a ground seat in the drill plate
• Overall length of 30 mm in the short version of the range short, medium and long
• Special case-hardening steel, hardened to 740 ± 80 HV 10 and ground
• Bore rounded on both sides to form B, so the bush can be fitted either way round

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 basis is DIN 179 for cylindrical drill bushes. Form B means a bore that is rounded on both sides. Made of special case-hardening steel, hardened to 740 ± 80 HV 10 and ground.
