Drill bush DIN 179 form A, bore 17 mm, length 28 mm, outside dia 26 mm, hardened steel

A drill of 17 mm diameter runs guided through 28 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

• Guide bore of 17 mm to DIN 179 for the matching tool
• Bore rounded on one side to form A, with a fixed fitting direction in the jig
• Outside diameter of 26 mm as a ground seat in the drill plate
• Guide length of about 1.6 drill diameters at 28 mm of length
• Special case-hardening steel, hardened to 740 ± 80 HV 10 and ground

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

The design corresponds to DIN 179, form A. Case-hardening steel at 740 ± 80 HV 10 together with ground surfaces determines the service life of the bush.
