Drill bush DIN 179 form B, short type, bore 6 mm, length 10 mm, outside dia 10 mm

During drilling in the jig this bush takes over the guidance of the 6 mm tool. The overall length of 10 mm sets the bearing surface of the drill in the short version, and the bore matches form B of DIN 179.

Benefits

• Outside diameter of 10 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
• Guide bore of 6 mm to DIN 179 for the matching tool
• Special case-hardening steel, hardened to 740 ± 80 HV 10 and ground
• Guide length of about 1.7 drill diameters at 10 mm of length
• Overall length of 10 mm in the short version of the range short, medium and long

Applications

• Series drilling on jigs with high piece numbers
• Drill templates for assembly work on site
• Guiding twist drills and reamers in the jig
• Repair of worn drill plates by replacement of the same size

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.
