Drill bush DIN 179 form A, bore 10.9 mm, length 25 mm, outside dia 18 mm, hardened steel

Where a hole of 10.9 mm has to sit in the same place on every part, this DIN 179 bush guides the tool. The long length of 25 mm supports the drill, and the bore is rounded on one side.

Benefits

• Guide bore of 10.9 mm to DIN 179 for the matching tool
• Special case-hardening steel, hardened to 740 ± 80 HV 10 and ground
• Wall thickness of 3.5 mm between the 10.9 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
