• Overall length of 6 mm in the short version of the range short, medium and long
• Guide length of about 2.6 drill diameters at 6 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

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.
