Description
The Dormer Pramet R520 6.80 mm carbide drill with a straight shank (DIN 6539) is built for dependable, precise drilling across a wide range of metals. With a 6.80 mm diameter and a DIN 6539-compatible straight shank, this drill fits standard chucks and holders, making it a versatile choice for engineers, machinists, and hobbyists alike. Its premium carbide core and Titanium Nitride coating deliver long life and consistent performance on steel, aluminium, and stainless steel.
A 130-degree point helps self-center the drill and reduces the pushing effort required to start a hole, while the TiN coating increases wear resistance for longer service life. Convex cutting edges improve chip control, enabling higher cutting speeds and feeds without sacrificing hole quality.
- 130° Self‑Centering Point: Improves hole start accuracy and reduces entry thrust for cleaner, more reliable starts.
- TiN Coating for Longer Life: Enhances wear resistance, extending tool life when drilling tougher materials like stainless steel and hardened alloys.
- Convex Cutting Edges for Efficient Cutting: Aids chip breaking and removal, enabling higher speeds and feeds with consistent hole quality (H8 tolerance).
The Dormer Pramet R520 delivers dependable, high-quality holes at speed across common metals, with a straight shank designed for quick changes and compatibility across standard equipment. This drill helps streamline workflows, reduces downtime, and provides repeatable results you can trust—ideal for production environments, maintenance tasks, and precision projects alike.
