About This

DURABLE AND STRONG: Genuine M2 high speed steel with the black coating ensures durability and sharpness, reduces the friction, runs cooler, performs well in heat, corrosion and rust resistance, for longer cutting edge life even at extreme temperatures
EXTRA LARGE STEPS DRILL: 10 size multiple hole stepped up bits, have many steps which contain multiple diameters, convenient to drill different hole size by using a step drill rather than many drills, ideal for DIY projects at home, garden, workshop
HIGH PERFORMANCE: Split tip is at 118 degrees for better wear resistance. Double helix blade design makes smoother cuts, easier to dislodge material particles and cleaner drilling operations, can be used with electric drills, rechargeable drills and more
ONE BIT FOR ALL DRILLING: One bit for 1/4" to 1-3/8" 10 steps hole sizes: 1/4", 3/8", 1/2", 5/8", 3/4", 7/8", 1", 1-1/8", 1-1/4", 1-3/8", so you can drill up holes with different diameters, saving your time and efforts to change bits
WELL DESIGNED: Provides stability during the drilling process, minimizes noise and vibration. To improve performance and extend drill bit life when working with metal, we recommend using cutting fluid for lubrication.(Cutting fluid not included)
