RUKO HGB-DIN2181-HSS-60°-7/16x Escareador, 3 arestas, 7/16 polegadas de diâmetro de corte, haste 8mm, comprimento 56mm

RUKO's HGB-DIN2181-HSS-60°-7/16x countersink bit stands out with its precision-ground 60° cutting angle and 7/16 inch cutting diameter, tailored for clean chamfering and deburring in a wide range of materials. Unlike generic countersinks, this tool is manufactured to DIN 2181, ensuring consistent geometry and reliable performance in steel, cast iron, non-ferrous metals, and plastics.

Highlights

• High-speed steel (HSS) construction for durability and heat resistance
• Three-flute design for smooth, chatter-free countersinking
• Right-hand cutting direction for standard drilling machines
• Cylindrical shank with 8 mm diameter for secure chucking
• Bright (uncoated) surface for sharp cutting edges

In daily use

The 56 mm overall length provides good reach while maintaining rigidity. Its conical head design centers easily on pre-drilled holes, producing uniform chamfers and countersinks for flat-head screws. Suitable for both manual and CNC applications where a precise 60° countersink is required.
