Collar drill bushing DIN 172 form A, bore 5.3 mm, length 10 mm, collar 13 mm, hardened steel

When drilling in jigs, this bushing keeps the 5.3 mm tool on position. The guiding length is 10 mm, the press fit measures 10 mm in diameter and the collar 13 mm.

Benefits

• Bore 5.3 mm, ground and dimensionally accurate to DIN 172
• Outside diameter 10 mm for the press fit in the drill plate
• Collar 13 mm with 3.0 mm height for axial location
• Overall length 10 mm in the short series
• Form A to DIN 172, the bore is rounded on the collar side so the tool enters easily
• Case-hardening steel, hardened to 740 ± 80 HV 10 and ground

Applications

It is typically fitted into the drill plates of jigs in mechanical engineering, contract manufacturing and mould making, where the same 5.3 mm hole is produced again and again in the same place.

Standard and material

The design complies with DIN 172 form A. In form A the bore is rounded only on the side of the collar. The material is case-hardening steel, hardened to 740 ± 80 HV 10 and ground.
