FANAR Broca helicoidal de metal duro 6,80 mm 5xD DIN 6537 L MASTERDRILL

The FANAR MASTERDRILL W9-614M33-0680 is a high-performance solid carbide twist drill designed for precision drilling in demanding materials. Manufactured to DIN 6537 L standard, this drill features a 6.80 mm diameter, 5xD drilling depth ratio, and internal coolant supply for efficient chip evacuation and extended tool life. The AlTiN coating provides excellent wear resistance and heat dissipation, making it ideal for high-speed machining of steel, stainless steel, cast iron, and non-ferrous metals.

Advantages

Self-centering point geometry ensures accurate hole positioning and reduces walking. The 140° point angle and optimized helix angle (30°) deliver smooth cutting action and superior chip removal. Internal coolant channels allow for effective cooling at the cutting edge, reducing thermal stress and improving surface finish. The cylindrical shank (HA8) ensures compatibility with standard tool holders.
