Drill bush DIN 179 form A, bore 3.2 mm, length 8 mm, outside dia 6 mm, case-hardened steel

The bush takes over the guidance of the drill directly at the workpiece. It is sized for a bore diameter of 3.2 mm and is 8 mm long. The material is special case-hardening steel, hardened to 740 ± 80 HV 10, which keeps wear of the guide low over many workpieces.

Benefits

• Guide bore of 3.2 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 A, that is rounded on one side
• Bore rounded on one side, giving a defined fitting direction in the jig

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
