Drill bush DIN 179 form B, bore 9.2 mm, length 25 mm, outside dia 15 mm, hardened steel

The long version of this DIN 179 bush guides drills of 9.2 mm over an overall length of 25 mm. In form B the bore is rounded on both sides, which makes work in the jig easier.

Benefits

• Guide bore of 9.2 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.
