Drill bush DIN 179 form B, bore 2.9 mm, length 8 mm, outside dia 6 mm, case-hardened steel

This drill bush guides tools of 2.9 mm diameter and keeps the drill axis in position over the full length of 8 mm. The bore follows form B of DIN 179 and is therefore rounded on both sides, which makes it easier to enter the drill.

Benefits

• Guide bore of 2.9 mm to DIN 179 for the matching drill
• Outside diameter of 6 mm as a ground seat in the jig plate
• Overall length of 8 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
• Bore rounded on both sides, so the bush can be fitted either way round

Applications

• Drilling jigs and drilling templates in series production
• 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
