Cylindrical drill bush DIN 179 form B, bore 5 mm, length 16 mm, outside dia 8 mm, ground

Where a hole of 5 mm has to sit in the same place on every part, this DIN 179 bush guides the tool. The long length of 16 mm supports the drill, and the bore is rounded on both sides.

Benefits

• Outside diameter of 8 mm as a ground seat in the drill plate
• Guide bore of 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 16 mm in the long version of the range short, medium and long
• Guide length of about 3.2 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

The bush is made to DIN 179 in form B, and the bore is rounded on both sides. The material is special case-hardening steel, hardened to 740 ± 80 HV 10 and ground.
