Cylindrical drill bush DIN 179 form B, bore 17.5 mm, length 36 mm, outside dia 26 mm

During drilling in the jig this bush takes over the guidance of the 17.5 mm tool. The overall length of 36 mm sets the bearing surface of the drill in the long version, and the bore matches form B of DIN 179.

Benefits

• Outside diameter of 26 mm as a ground seat in the drill plate
• Guide bore of 17.5 mm to DIN 179 for the matching tool
• Bore rounded on both sides to form B, so the bush can be fitted either way round
• Overall length of 36 mm in the long version of the range short, medium and long
• Guide length of about 2.1 drill diameters at 36 mm of length

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
