Drill bush DIN 179 form B, medium type, bore 9.1 mm, length 20 mm, outside dia 15 mm

This drill bush guides tools of 9.1 mm diameter and keeps the drilling axis in position over the full length of 20 mm. The bore follows form B of DIN 179 and is therefore 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 9.1 mm to DIN 179 for the matching tool
• Dimensions to DIN 179, so existing bushes can be replaced size for size
• Outside diameter of 15 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
