Cylindrical drill bush DIN 179 form B, bore 15.5 mm, length 28 mm, outside dia 26 mm, ground

Where a hole of 15.5 mm has to sit in the same place on every part, this DIN 179 bush guides the tool. The medium length of 28 mm supports the drill, and the bore is rounded on both sides.

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 15.5 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 5.2 mm between the 15.5 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
