Cylindrical drill bush DIN 179 form B, bore 10.3 mm, length 20 mm, outside dia 18 mm

For repeatable holes of 10.3 mm diameter this bush is seated in the drill plate by its ground outside diameter of 18 mm. The drill stays guided across 20 mm of length, and the bore is rounded on both sides.

Benefits

• Bore rounded on both sides to form B, so the bush can be fitted either way round
• Overall length of 20 mm in the medium version of the range short, medium and long
• Guide bore of 10.3 mm to DIN 179 for the matching tool
• Dimensions to DIN 179, so existing bushes can be replaced size for size
• Outside diameter of 18 mm as a ground seat in the drill plate

Applications

• Drilling jigs and drill templates in series production
• Jig and tool making
• Repeatable hole patterns in sheet metal, profiles and housings
• Maintenance work where hole patterns are reworked

Standard and material

The design corresponds to DIN 179, form B. Case-hardening steel at 740 ± 80 HV 10 together with ground surfaces determines the service life of the bush.
