Cylindrical drill bush DIN 179 form A, bore 6 mm, length 20 mm, outside dia 10 mm, ground

For repeatable holes of 6 mm diameter this bush is seated in the drill plate by its ground outside diameter of 10 mm. The drill stays guided across 20 mm of length, and the bore is rounded on one side.

Benefits

• Special case-hardening steel, hardened to 740 ± 80 HV 10 and ground
• Guide bore of 6 mm to DIN 179 for the matching tool
• Outside diameter of 10 mm as a ground seat in the drill plate
• Bore rounded on one side to form A, with a fixed fitting direction in the jig
• Dimensions to DIN 179, so existing bushes can be replaced size for size

Applications

• Drilling jigs and drill templates in series production
• Jig and tool making
• Repeatable hole patterns in sheet metal, profiles and housings
• Maintenance work where hole patterns are reworked

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.
