Drill bush DIN 179 form A, medium type, bore 23 mm, length 36 mm, outside dia 35 mm

Where a hole of 23 mm has to sit in the same place on every part, this DIN 179 bush guides the tool. The medium length of 36 mm supports the drill, and the bore is rounded on one side.

Benefits

• Outside diameter of 35 mm as a ground seat in the drill plate
• Bore rounded on one side to form A, with a fixed fitting direction in the jig

• Guide length of about 1.6 drill diameters at 36 mm of length
• Overall length of 36 mm in the medium version of the range short, medium and long

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
