Drill bush DIN 179 form A, bore 8.9 mm, length 20 mm, outside dia 15 mm, case-hardened steel

The material, hardened to 740 ± 80 HV 10, keeps the 8.9 mm guide bore accurate even after many drilling cycles. The outside diameter measures 15 mm. The bore follows form A of DIN 179 and is therefore rounded on one side, which makes it easier to enter the drill.

Benefits

• Guide bore of 8.9 mm to DIN 179 for the matching drill
• Outside diameter of 15 mm as a ground seat in the jig plate
• Overall length of 20 mm in the medium 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
