Noga BC2012 Deburring Countersink Blade 3/4 Inch Hss

Product Description

The NOGA BC2012 is a Type C20 replacement deburring countersink blade designed for front hole chamfering on a range of common materials. Machined from High Speed Steel (HSS), it handles the edge-breaking and countersinking demands of production and maintenance environments without dulling under repeated use. The right-handed blade orientation suits standard rotary deburring tools and is sized for a maximum head diameter of 0.75 inches. Machinists, pipefitters, and fabricators install this blade when refacing drilled holes in aluminum, plastic, or steel workpieces before fastener seating or assembly.

This countersink blade is suited for bench-level deburring operations as well as in-field work where clean chamfers are required on drilled or punched holes. It is appropriate for both shop and field use across light fabrication, HVAC sheet metal work, plumbing rough-in, and general mechanical assembly. Its front chamfer geometry makes it effective for cleaning up hole entries on panel stock, pipe ends, and structural components in residential and light commercial applications.

Installation Notes

Installation of this replacement blade should be performed by a qualified machinist or tradesperson familiar with rotary deburring tool systems.

Use the appropriate blade-change tool or key specified for the S-series holder to avoid hand injury. Verify the blade is fully seated and locked before returning the tool to service.
