The Noga Deburring Blade, Reversible Countersink is a precision countersink and deburring blade for the Noga rotary deburring system. Designed to chamfer hole edges and remove burrs from drilled or punched holes simultaneously, this blade delivers a consistent countersink angle and finish in a single operation. The swivelling cutter head follows the hole edge automatically, producing a clean, controlled chamfer without the need for a drill press or stand.Where this tool is used Metal fabrication and machining shops chamfering drilled holes in steel, aluminium and stainless steel plate prior to fastener installation Aerospace and automotive component manufacturing where hole edge preparation to a precise chamfer angle is a process requirement Sheet metal work where punched holes require deburring and chamfering before assembly, welding or powder coating Key specifications Specification Detail Type Rotary countersink/deburring blade Material High Speed Steel (HSS) Application Hole chamfering and edge deburring Compatible system Noga rotary deburring handle system Operation Hand-held; no power tool required Selecting the right optionThe Noga countersink blade range covers light through to heavy-duty chamfering requirements.
