Drill bush DIN 179 form B, bore 27.5 mm, length 45 mm, outside dia 42 mm, hardened steel

During drilling in the jig this bush takes over the guidance of the 27.5 mm tool. The overall length of 45 mm sets the bearing surface of the drill in the medium version, and the bore matches form B of DIN 179.

Benefits

• Guide bore of 27.5 mm to DIN 179 for the matching tool
• Special case-hardening steel, hardened to 740 ± 80 HV 10 and ground
• Wall thickness of 7.2 mm between the 27.5 mm bore and the 42 mm seat
• Bore rounded on both sides to form B, so the bush can be fitted either way round
• Overall length of 45 mm in the medium version of the range short, medium and long

Applications

• Hole patterns in assembly jigs and equipment frames
• Workshop production with changing workpieces
• Redrilling and opening up holes on existing jigs
• Pattern making and mould making
