Drill bush DIN 179 form B, bore 28 mm, length 45 mm, outside dia 42 mm, case-hardened steel

When drilling identical parts in series, this bush keeps the 28 mm hole in the same place from part to part. The overall length is 45 mm. The material is special case-hardening steel, hardened to 740 ± 80 HV 10, which keeps wear of the guide low over many workpieces.

Benefits

• Guide bore of 28 mm to DIN 179 for the matching drill
• Outside diameter of 42 mm as a ground seat in the jig plate
• Overall length of 45 mm in the medium version of the three lengths short, medium and long
• Special case-hardening steel, hardened to 740 ± 80 HV 10 and ground
• Bore to form B, that is rounded on both sides
• Bore rounded on both sides, so the bush can be fitted either way round

Applications

• Drilling jigs and drilling templates in series production
• Jig and fixture construction as well as tool making
• Holes in sheet metal, profiles and housings that have to be repeatable in position and diameter
• Maintenance and repair work when hole patterns are reworked
