Drill bush DIN 179 form B, bore 9.7 mm, length 25 mm, outside dia 15 mm, hardened steel

With a guide bore of 9.7 mm this bush to DIN 179 accepts the drill and supports it over 25 mm of length. In form B the bore is rounded on both sides, and the seat in the jig measures 15 mm.

Benefits

• Guide bore of 9.7 mm to DIN 179 for the matching tool
• Outside diameter of 15 mm as a ground seat in the drill plate
• Bore rounded on both sides to form B, so the bush can be fitted either way round
• 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 B. Case-hardening steel at 740 ± 80 HV 10 together with ground surfaces determines the service life of the bush.
