Drill bush DIN 179 form B, bore 42 mm, length 30 mm, outside dia 55 mm, hardened steel

The short version of this DIN 179 bush guides drills of 42 mm over an overall length of 30 mm. In form B the bore is rounded on both sides, which makes work in the jig easier.

Benefits

• Guide bore of 42 mm to DIN 179 for the matching tool
• Outside diameter of 55 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
