Drill bush DIN 179 form B, medium type, bore 38 mm, length 56 mm, outside dia 55 mm

Where a hole of 38 mm has to sit in the same place on every part, this DIN 179 bush guides the tool. The medium length of 56 mm supports the drill, and the bore is rounded on both sides.

Benefits

• Bore rounded on both sides to form B, so the bush can be fitted either way round
• Outside diameter of 55 mm as a ground seat in the drill plate
• Guide length of about 1.5 drill diameters at 56 mm of length
• Special case-hardening steel, hardened to 740 ± 80 HV 10 and ground

• 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
