Drill bush DIN 179 form A, bore 5.5 mm, length 10 mm, outside dia 10 mm, case-hardened steel

When drilling identical parts in series, this bush keeps the 5.5 mm hole in the same place from part to part. The overall length is 10 mm. The 10 mm seat and the 5.5 mm bore are ground, so the bush can be pressed into the fixture without any rework.

Benefits

• Outside diameter of 10 mm as a ground seat in the jig plate
• Overall length of 10 mm in the short version of the three lengths short, medium and long
• Special case-hardening steel, hardened to 740 ± 80 HV 10 and ground
• Bore to form A, that is rounded on one side
• Guide bore of 5.5 mm to DIN 179 for the matching drill
• Bore rounded on one side, giving a defined fitting direction in the jig

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
