Countersink Ø6.3 mm 90° DIN 335 C HSS is a precision tool designed for professional hole machining with a countersinking angle of ninety degrees. Made from high-speed steel (HSS), it offers exceptional abrasion resistance and high durability under heavy cutting conditions.
With 3 cutting edges, which stabilize the machining process, the tool produces an exceptionally smooth countersunk surface and reduces vibration. This directly results in higher productivity and less frequent tool replacement, particularly when working with more difficult materials.
Application countersink for metal includes countersinking predrilled holes for flat head screws, as well as deburring and improving the quality of end faces. It is ideal for working with stainless steel, delivering productivity and precision unattainable with lower-cost alternatives.
The high-quality tool surface reduces friction and aids chip evacuation, increasing tool life and machining quality. The product complies with DIN 335 C, has a straight shank and is designed for use on conventional machine tools, drilling machines and CNC machining centers.
- High operating stability – three precision cutting edges ensure uniform cutting without vibration.
- Extended tool life – heat-resistant HSS extends the tool's operating life.
- Universal application – suitable for working with metals as well as machining stainless steel.
- Compliance with DIN 335 C – ensures full compatibility with industrial systems and assembly tools.
An ideal choice for professionals seeking a durable and precise Ø6.3 mm 90° countersink for stainless steel, which meets expectations even under demanding machining conditions.
