NO NAME P.C309250 DIN 335-C 90° 25 mm HSSE TiN Φρεζοκέφαλο (EL-CUT)

Precision chamfering and deburring demand a tool that holds its edge and cuts cleanly through tough materials. This DIN 335-C conical countersink, crafted from cobalt-alloyed HSSE with a titanium nitride coating, delivers exactly that—combining durability with a smooth, chatter-free finish. Whether you're preparing holes for fasteners or finishing metalwork, this 90° countersink is built for consistent, professional results.

Highlights

• 90° cutting angle for standard 90° countersunk screws
• 25 mm cutting diameter handles a wide range of hole sizes
• HSSE (HSS with cobalt) for enhanced heat resistance and edge retention
• TiN coating reduces friction and extends tool life
• 3-flute design for efficient chip removal and reduced vibration

In daily use

When you need to deburr a freshly drilled hole or create a clean seat for a countersunk screw, this countersink bit is ready. Its right-hand cut and cylindrical 10 mm shank fit standard drill chucks, while the ground flutes ensure a precise, concentric cut. The TiN coating not only protects against wear but also helps the tool glide through stainless steel and other alloys with less heat buildup. For optimal performance and longer tool life, use a suitable coolant or cutting fluid.
