Cylindrical drill bush DIN 179 form A, bore 41 mm, length 56 mm, outside dia 55 mm, ground

During drilling in the jig this bush takes over the guidance of the 41 mm tool. The overall length of 56 mm sets the bearing surface of the drill in the medium version, and the bore matches form A of DIN 179.

Benefits

• Special case-hardening steel, hardened to 740 ± 80 HV 10 and ground
• Guide bore of 41 mm to DIN 179 for the matching tool
• Outside diameter of 55 mm as a ground seat in the drill plate
• Bore rounded on one side to form A, with a fixed fitting direction in the jig
• Dimensions to DIN 179, so existing bushes can be replaced size for size

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
