Cylindrical drill bush DIN 179 form B, bore 16 mm, length 28 mm, outside dia 26 mm, ground

During drilling in the jig this bush takes over the guidance of the 16 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

• 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
• Guide bore of 16 mm to DIN 179 for the matching tool
• Overall length of 28 mm in the medium version of the range short, medium and long
• Wall thickness of 5 mm between the 16 mm bore and the 26 mm seat

Applications

• Drilling jigs and drill templates in series production
• Jig and tool making
• Repeatable hole patterns in sheet metal, profiles and housings
• Maintenance work where hole patterns are reworked
