Collar drill bushing DIN 172 form A, bore 1.2 mm, length 9 mm, collar 6 mm, hardened steel

With a ground bore of 1.2 mm this bushing holds the tool on position over a guiding section of 9 mm. The collar of 6 mm diameter and 2.0 mm height stops the bushing from travelling through the fixture while drilling.

Benefits

• Bore 1.2 mm, ground and dimensionally accurate to DIN 172
• Collar 6 mm with 2.0 mm height for axial location
• Overall length 9 mm in the medium series
• Outside diameter 4 mm for a press fit in the drill plate
• Form A to DIN 172 with the bore rounded on the collar side, so the tool enters easily
• Case-hardening steel hardened to 740 ± 80 HV 10

Applications

Typical fields of use are drilling templates, fixtures for small batch and series production, mould making and maintenance.

Standard and material

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