RUKO KES-DIN335-HSS-90°-Ø16,5 mm escareador cónico

The RUKO KES-DIN335-HSS-90°-Ø16.5mm is a precision ground 3-flute countersink engineered for clean 90° chamfers, deburring, and countersinking in a wide range of materials. Unlike standard countersinks with fewer flutes, its three cutting edges reduce chatter and deliver a smoother finish, while the DIN 335 C geometry ensures consistent centering and repeatable results in both manual and CNC applications.

Highlights

• 90° cutting angle for standard countersunk screws
• 3-flute design for reduced vibration and improved surface quality
• High-speed steel (HSS) construction for durability and resharpening capability
• Cylindrical shank with 10 mm diameter for secure chucking
• Precision ground for accurate cutting geometry

In daily use

Whether you are preparing holes for flat-head screws in steel, cast iron, non-ferrous metals, plastics, or wood, this countersink delivers clean, burr-free results. Its right-hand cutting direction and uncoated finish make it suitable for general-purpose work up to 900 N/mm² hardness. The 60 mm overall length and 16.5 mm cutting diameter offer a balanced reach for most drilling and milling setups.
