Product description
- Specially developed for use in cordless drills
- Best surface quality: enables precise, round, chatter-free countersinking
- Made of cobalt-alloyed high-speed steel – heat-resistant and durable
- 3-sided shank – no slipping in the drill chuck
- Low-effort drilling
HSS-Co5 U-groove countersink 90° – precise countersinking with high load capacity
The HSS-Co5 U-groove countersink 90° combines precise machining with a long tool life and efficient operation. Unequal spacing and cobalt-alloyed high-speed steel enable precise, chatter-free countersinking even in demanding materials.
The premium countersink according to DIN 335 Form C is designed for professional applications. The cutting edges ensure uniform material removal and high efficiency during machining. The unequal spacing reduces vibrations and supports smooth machining. This produces precise, round countersinks with very good surface quality.
The 3-sided shank prevents the precision tool from slipping in the drill chuck. This improves power transmission and facilitates controlled machining. At the same time, the sophisticated cutting edge geometry enables low-force drilling. Especially for repetitive tasks, this contributes to an efficient workflow.
Made of HSS-Co5 high-speed steel with 5% cobalt, the cutting tool impresses with its high heat resistance and load capacity. Even under intensive use, the precision tool remains durable and reliable. The robust material quality is therefore suitable for demanding applications in workshops, production and assembly.
The countersink has been specially developed for use in cordless drills. In this way, precise machining can also be reliably achieved during mobile work. The tool is suitable for machining alloyed and high-alloyed steel, cast iron, stainless steel, titanium and special alloys. Especially with difficult-to-machine materials, the stable model and the precise cutting edge geometry support clean results with reduced effort.
