Drill bush DIN 179 form A, bore 9.8 mm, length 12 mm, outside dia 15 mm, case-hardened steel

The material, hardened to 740 ± 80 HV 10, keeps the 9.8 mm guide bore accurate even after many drilling cycles. The outside diameter measures 15 mm. The 15 mm seat and the 9.8 mm bore are ground, so the bush can be pressed into the fixture without any rework.

Benefits

• Bore to form A, that is rounded on one side
• Guide bore of 9.8 mm to DIN 179 for the matching drill
• Outside diameter of 15 mm as a ground seat in the jig plate
• Overall length of 12 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 rounded on one side, giving a defined fitting direction in the jig

Applications

• 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
• Holes in sheet metal, profiles and housings that have to be repeatable in position and diameter
