Drill bush DIN 179 form B, bore 8.2 mm, length 25 mm, outside dia 15 mm, case-hardened steel

The material, hardened to 740 ± 80 HV 10, keeps the 8.2 mm guide bore accurate even after many drilling cycles. The outside diameter measures 15 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

• Bore to form B, that is rounded on both sides
• Guide bore of 8.2 mm to DIN 179 for the matching drill
• Outside diameter of 15 mm as a ground seat in the jig plate
• Overall length of 25 mm in the long version of the three lengths short, medium and long
• Bore rounded on both sides, so the bush can be fitted either way round

Applications

• Maintenance and repair work when hole patterns are reworked
• Gauge making and prototype work in small batches
• Drilling jigs and drilling templates in series production
• Jig and fixture construction as well as tool making
