Cylindrical drill bush DIN 179 form A, bore 28.5 mm, length 45 mm, outside dia 42 mm

A drill of 28.5 mm diameter runs guided through 45 mm of this bush and meets the hole at the intended point. The design follows DIN 179, form A, and the bore is rounded on one side.

Benefits

• Bore rounded on one side to form A, with a fixed fitting direction in the jig
• Guide bore of 28.5 mm to DIN 179 for the matching tool
• Special case-hardening steel, hardened to 740 ± 80 HV 10 and ground
• Outside diameter of 42 mm as a ground seat in the drill plate
• Guide length of about 1.6 drill diameters at 45 mm of length

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

Standard and material
