Cylindrical drill bush DIN 179 form B, bore 17 mm, length 28 mm, outside dia 26 mm, ground

During drilling in the jig this bush takes over the guidance of the 17 mm tool. The overall length of 28 mm sets the bearing surface of the drill in the medium version, and the bore matches form B of DIN 179.

Benefits

• Outside diameter of 26 mm as a ground seat in the drill plate
• Bore rounded on both sides to form B, so the bush can be fitted either way round
• Guide bore of 17 mm to DIN 179 for the matching tool
• Special case-hardening steel, hardened to 740 ± 80 HV 10 and ground
• Guide length of about 1.6 drill diameters at 28 mm of length
• Overall length of 28 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
