Drill bush DIN 179 form B, bore 5.6 mm, length 10 mm, outside dia 10 mm, case-hardened steel

The short version of 10 mm overall length is intended for thin jig plates and low overall height and guides drills of 5.6 mm diameter. Form B to DIN 179 means that the bore is rounded on both sides, while the outside diameter of 10 mm determines the fit in the fixture.

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 B, that is rounded on both sides
• Guide bore of 5.6 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
