Collar drill bushing form B to DIN 172, bore 8 x 10 mm, collar 15 mm, case-hardening steel

With a bore of 8 mm and an overall length of 10 mm, this bushing keeps the tool on track inside the drilling jig. The collar of 15 mm diameter and 3.0 mm height bears on the drill plate and secures the bushing against axial slipping.

Benefits

• Bore 8 mm, ground and dimensionally accurate to DIN 172
• Collar 15 mm with 3.0 mm height for axial location
• Outside diameter 12 mm for the press fit in the drill plate
• Case-hardening steel, hardened to 740 ± 80 HV 10 and ground
• Overall length 10 mm in the short series
• Form B to DIN 172, the bore is rounded on both sides and can be loaded from either end

Applications

It suits drilling jigs, drill templates and assembly fixtures in which the tool has to be guided safely over 10 mm, even with frequent tool changes.
