RUKO Avellanador cónico DIN 335 C HSS TiAlN 90° 10,0 mm

Machinists and metalworkers needing clean, precise chamfers on steel or stainless steel will appreciate the RUKO countersink bit. With a 10.0 mm cutting diameter and a 90° cutting angle, it produces accurate countersinks for screws and deburrs edges in a single pass. The TiAlN coating on high-speed steel provides high wear resistance and heat resistance, making it suitable for dry machining of harder materials.

Key specifications

• Tool Type: Countersink
• Standard: DIN 335 C
• Material: High-Speed Steel (HSS)
• Coating: Titanium Aluminum Nitride (TiAlN)
• Cutting Angle: 90°
• Cutting Diameter (D1): 10.0 mm
• Shank Diameter (D2): 6 mm

Why choose it

The TiAlN coating delivers very high wear resistance and high heat resistance, extending tool life and allowing dry machining. The three cutting edges ensure smooth, chatter-free countersinking, while the DIN 335 C geometry provides a standard 90° angle for common screw heads.

Ideal use cases

• Countersinking holes for flat-head screws in steel and stainless steel
• Deburring drilled holes in cast iron and non-ferrous metals
• Chamfering edges on plastic components

Good to know

Suitable for universal application, especially for harder materials. The cylindrical shank fits standard drill chucks. For best results, use with a suitable cutting fluid or dry as recommended.
