Cylindrical drill bush DIN 179 form B, bore 3 mm, length 8 mm, outside dia 6 mm

Where a hole of 3 mm has to sit in the same place on every part, this DIN 179 bush guides the tool. The short length of 8 mm supports the drill, and the bore is rounded on both sides.

Benefits

• Overall length of 8 mm in the short version of the range short, medium and long
• Guide bore of 3 mm to DIN 179 for the matching tool
• Dimensions to DIN 179, so existing bushes can be replaced size for size
• Outside diameter of 6 mm as a ground seat in the drill plate

Applications

• Fixed drill plates and hinged drilling jigs
• One-off and small batch production in mechanical engineering
• Drilling fitted holes on assemblies with a fixed hole position
• Inspection and marking templates in assembly
