Drill bush DIN 179 form A, medium type, bore 43.5 mm, length 56 mm, outside dia 62 mm

This drill bush guides tools of 43.5 mm diameter and keeps the drilling axis in position over the full length of 56 mm. The bore follows form A of DIN 179 and is therefore rounded on one side.

Benefits

• Special case-hardening steel, hardened to 740 ± 80 HV 10 and ground
• Guide bore of 43.5 mm to DIN 179 for the matching tool
• Outside diameter of 62 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
• Dimensions to DIN 179, so existing bushes can be replaced size for size

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
