Drill bush DIN 179 form B, bore 13.7 mm, length 36 mm, outside dia 22 mm, case-hardened steel

The bush takes over the guidance of the drill directly at the workpiece. It is sized for a bore diameter of 13.7 mm and is 36 mm long. Form B to DIN 179 means that the bore is rounded on both sides, while the outside diameter of 22 mm determines the fit in the fixture.

Benefits

• Special case-hardening steel, hardened to 740 ± 80 HV 10 and ground
• Bore to form B, that is rounded on both sides
• Guide bore of 13.7 mm to DIN 179 for the matching drill
• Outside diameter of 22 mm as a ground seat in the jig plate
• Overall length of 36 mm in the long version of the three lengths short, medium and long
