Designed for demanding applications, this premium drill bit delivers faster drilling speeds, efficient chip removal, and extended durability, making it a reliable choice for professional users and heavy-duty projects.

Its advanced variable helix flute design (35° to 15°) helps remove chips quickly while reducing heat buildup, allowing the cutting edge to stay sharper for longer periods.
