Cylindrical drill bush DIN 179 form B, bore 5 mm, length 12 mm, outside dia 8 mm

The medium version of this DIN 179 bush guides drills of 5 mm over an overall length of 12 mm. In form B the bore is rounded on both sides, which makes work in the jig easier.

Benefits

• Bore rounded on both sides to form B, so the bush can be fitted either way round
• Guide bore of 5 mm to DIN 179 for the matching tool
• Special case-hardening steel, hardened to 740 ± 80 HV 10 and ground
• Outside diameter of 8 mm as a ground seat in the drill plate
• Guide length of about 2.4 drill diameters at 12 mm of length

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.
