RUKO SPB-DIN338-HSS-G-Cruz 14,5 mm Broca helicoidal, afiação em cruz, DIN 338

This RUKO twist drill bit stands out with its fully ground HSS-G construction and split point tip, engineered for precise centering and reduced walking on contact. The 14.5 mm diameter and DIN 338 compliance make it a dependable choice for demanding drilling tasks in metal and other materials.

Highlights

• Split point tip (135°) for self-centering and accurate hole positioning
• Fully ground from high-speed steel (HSS-G) for durability and sharpness
• DIN 338 standard dimensions ensure compatibility with standard drill chucks
• Bright, uncoated finish for clean cutting and easy inspection
• Right-hand cutting direction for conventional drilling

In daily use

The split point geometry eliminates the need for center punching, saving time and improving accuracy. The normal helix angle (Type N) provides efficient chip evacuation in a wide range of materials, including steel, cast iron, non-ferrous metals, and plastics. The cylindrical shank fits securely in standard three-jaw chucks.
