Drill bush DIN 179 form B, bore 10.4 mm, length 25 mm, outside dia 18 mm, case-hardened steel

When drilling identical parts in series, this bush keeps the 10.4 mm hole in the same place from part to part. The overall length is 25 mm. Form B to DIN 179 means that the bore is rounded on both sides, while the outside diameter of 18 mm determines the fit in the fixture.

Benefits

• 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 10.4 mm to DIN 179 for the matching drill
• Outside diameter of 18 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
