Cylindrical drill bush DIN 179 form B, bore 3.3 mm, length 16 mm, outside dia 6 mm

This drill bush guides tools of 3.3 mm diameter and keeps the drilling axis in position over the full length of 16 mm. The bore follows form B of DIN 179 and is therefore rounded on both sides.

Benefits

• Outside diameter of 6 mm as a ground seat in the drill plate
• Guide bore of 3.3 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 16 mm in the long version of the range short, medium and long
• Guide length of about 4.8 drill diameters at 16 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

Standard and material
