Cylindrical drill bush DIN 179 form A, bore 8.1 mm, length 12 mm, outside dia 15 mm

This drill bush guides tools of 8.1 mm diameter and keeps the drilling axis in position over the full length of 12 mm. The bore follows form A of DIN 179 and is therefore rounded on one side.

Benefits

• Guide bore of 8.1 mm to DIN 179 for the matching tool
• Outside diameter of 15 mm as a ground seat in the drill plate
• Bore rounded on one side to form A, with a fixed fitting direction in the jig
• Special case-hardening steel, hardened to 740 ± 80 HV 10 and ground

Applications

• Hole patterns in assembly jigs and equipment frames
• Workshop production with changing workpieces
• Redrilling and opening up holes on existing jigs
• Pattern making and mould making

Standard and material

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