Drill bush DIN 179 form A, bore 48 mm, length 67 mm, outside dia 62 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 48 mm and is 67 mm long. The 62 mm seat and the 48 mm bore are ground, so the bush can be pressed into the fixture without any rework.

Benefits

• Outside diameter of 62 mm as a ground seat in the jig plate
• Overall length of 67 mm in the long 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
• Guide bore of 48 mm to DIN 179 for the matching drill
• Bore rounded on one side, giving a defined fitting direction in the jig

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
