Drill bush DIN 179 form B, short type, bore 5.8 mm, length 10 mm, outside dia 10 mm

During drilling in the jig this bush takes over the guidance of the 5.8 mm tool. The overall length of 10 mm sets the bearing surface of the drill in the short version, and the bore matches form B of DIN 179.

Benefits

• Special case-hardening steel, hardened to 740 ± 80 HV 10 and ground
• Bore rounded on both sides to form B, so the bush can be fitted either way round
• Guide bore of 5.8 mm to DIN 179 for the matching tool
• Overall length of 10 mm in the short version of the range short, medium and long
• Wall thickness of 2.1 mm between the 5.8 mm bore and the 10 mm seat

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 design corresponds to DIN 179, form B. Case-hardening steel at 740 ± 80 HV 10 together with ground surfaces determines the service life of the bush.
