Cylindrical drill bush DIN 179 form B, bore 47 mm, length 56 mm, outside dia 62 mm

This drill bush guides tools of 47 mm diameter and keeps the drilling axis in position over the full length of 56 mm. The bore follows form B of DIN 179 and is therefore rounded on both sides.

Benefits

• Guide bore of 47 mm to DIN 179 for the matching tool
• Bore rounded on both sides to form B, so the bush can be fitted either way round
• Outside diameter of 62 mm as a ground seat in the drill plate
• Guide length of about 1.2 drill diameters at 56 mm of length
• 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 B. Case-hardening steel at 740 ± 80 HV 10 together with ground surfaces determines the service life of the bush.
