Cylindrical drill bush DIN 179 form A, bore 14.4 mm, length 36 mm, outside dia 22 mm, ground

For repeatable holes of 14.4 mm diameter this bush is seated in the drill plate by its ground outside diameter of 22 mm. The drill stays guided across 36 mm of length, and the bore is rounded on one side.

Benefits

• Outside diameter of 22 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
• Guide bore of 14.4 mm to DIN 179 for the matching tool
• Special case-hardening steel, hardened to 740 ± 80 HV 10 and ground
• Guide length of about 2.5 drill diameters at 36 mm of length
• Overall length of 36 mm in the long version of the range short, medium and long

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.
