Drill bush DIN 179 form A, bore 11.4 mm, length 25 mm, outside dia 18 mm, hardened steel

During drilling in the jig this bush takes over the guidance of the 11.4 mm tool. The overall length of 25 mm sets the bearing surface of the drill in the long version, and the bore matches form A of DIN 179.

Benefits

• Guide bore of 11.4 mm to DIN 179 for the matching tool
• Special case-hardening steel, hardened to 740 ± 80 HV 10 and ground
• Wall thickness of 3.3 mm between the 11.4 mm bore and the 18 mm seat
• Bore rounded on one side to form A, with a fixed fitting direction in the jig
• Overall length of 25 mm in the long version of the range short, medium and long

Applications

• Drilling jigs and drill templates in series production
• Jig and tool making
• Repeatable hole patterns in sheet metal, profiles and housings
• Maintenance work where hole patterns are reworked

Standard and material
