Cylindrical drill bush DIN 179 form A, bore 2.4 mm, length 9 mm, outside dia 5 mm

This drill bush guides tools of 2.4 mm diameter and keeps the drilling axis in position over the full length of 9 mm. The bore follows form A of DIN 179 and is therefore rounded on one side.

Benefits

• Guide bore of 2.4 mm to DIN 179 for the matching tool
• Special case-hardening steel, hardened to 740 ± 80 HV 10 and ground
• Wall thickness of 1.3 mm between the 2.4 mm bore and the 5 mm seat
• Bore rounded on one side to form A, with a fixed fitting direction in the jig
• Overall length of 9 mm in the medium version of the range short, medium and long

Applications

• Fixed drill plates and hinged drilling jigs
• One-off and small batch production in mechanical engineering
• Drilling fitted holes on assemblies with a fixed hole position
• Inspection and marking templates in assembly

Standard and material

The basis is DIN 179 for cylindrical drill bushes. Form A means a bore that is rounded on one side. Made of special case-hardening steel, hardened to 740 ± 80 HV 10 and ground.
