Drill bush DIN 179 form B, bore 13.5 mm, length 36 mm, outside dia 22 mm, case-hardened steel

With an outside diameter of 22 mm the bush is seated in the bore of the jig plate and guides the drill of 13.5 mm nominal diameter. The 22 mm seat and the 13.5 mm bore are ground, so the bush can be pressed into the fixture without any rework.

Benefits

• Outside diameter of 22 mm as a ground seat in the jig plate
• Overall length of 36 mm in the long 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
• Guide bore of 13.5 mm to DIN 179 for the matching drill
• Bore rounded on both sides, so the bush can be fitted either way round

Applications

• 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
• Gauge making and prototype work in small batches
