DEWALT DT70755-QZ HSS-G Metal Drill Bit Set, 10 Pieces, 1/4 inch Hex Shank, 135° Split Point, DIN 338, TSTAK Tough Case

Drilling precise holes in metal, wood, and plastic can be a challenge with standard bits that wander, overheat, or dull quickly. The DEWALT DT70755-QZ HSS-G Metal Drill Bit Set solves these frustrations with precision-ground, high-speed steel bits engineered for accuracy and durability. The 135° split point starts on contact, eliminating walking and reducing the need for center punching, while the 1/4" hex shank provides a secure, slip-free grip in both cordless drills and impact drivers. Packed in a compact TSTAK-compatible Tough Case, this 10-piece set keeps your bits organized and ready for any job.

Who is it for

This set is ideal for professional tradespeople, metal fabricators, maintenance technicians, and serious DIYers who need reliable, accurate drilling across a range of materials. Whether you’re working with sheet metal, aluminum profiles, hardwood, or plastic enclosures, these bits deliver clean, burr-free holes. The hex shank design makes them especially useful for users who frequently switch between a drill and an impact driver, while the tough case suits mobile professionals who need organized tool storage.

Tips

For best results in metal, use a suitable cutting fluid or light oil to reduce heat and extend bit life. When drilling larger holes, start with a smaller pilot bit to improve accuracy. The split point design works best at moderate speed—let the tool do the work without excessive pressure. Store the bits in the Tough Case and snap it into your TSTAK stack to keep your workspace organized and your bits protected.
