Long lasting high speed steel: made of HSS for extended life and wear resistance, with a robust core for fatigue resistance in frequent use. Secure grip and efficient drilling: anti slip design reduces slipping; precision hex shank ensures optimal torque transfer to compatible power tools. Fast, clean holes: square cutting design enables faster drilling with smoother edges and less friction. Efficient heat management: heat channel design keeps the edge sharp at high temperatures; step body distributes heat evenly; HSS improves thermal conductivity for sustained performance. Versatile and compatible: fits standard drills and drivers with hex shank; suitable for metal sheets, aluminum, and thinner plastics; provides multiple hole sizes in a single bit. Practical use scenarios: - Electrical panel work: create knockouts in sheet metal for wiring. - Mounting hardware in aluminum enclosures or cabinets. - DIY projects involving thin metal or plastic panels requiring progressively larger holes.
