Description
The HSS Cobalt Cross Hole 90° Deburrer Countersink is a versatile finishing tool engineered for professional metalworking and fabrication applications.
The unique cross hole design allows efficient chip evacuation while delivering smooth, chatter-free countersinks and burr removal. Fully ground from M42 HSS-Co8 cobalt steel, this tool provides superior heat resistance, edge retention, and extended service life compared to standard HSS countersinks.
Ideal for both countersinking and deburring, it performs exceptionally well in ferrous metals such as mild steel and stainless steel, as well as aluminium, brass, plastics, and timber.
