Special Features
【Multi-size Countersink Bits】this set of countersink bits includes 5 different sizes - 1/4"(6.3mm), 3/8"(9.5mm), 1/2"(12.7mm), 5/8"(15.8 mm), 3/4"(19mm). These bits are available in multiple sizes and come in a convenient plastic storage box
【Enhanced Durability】these metal countersunk drill bits are crafted from high-quality M35 HSS material, known for its exceptional wear resistance, heat resistance, corrosion resistance, and impact resistance. This ensures reduced friction, lower operating temperature, and significantly improved service life . Additionally, the cobalt coating helps maintain sharpness, providing better durability and an extended lifespan
【Precise Grinding】With an 82-degree tip, these drill bits can easily countersink holes in a wide range of materials, including medium-hard stainless steel, metal, plywood, softwood, hardwood, fiberglass plastic, mild steel, copper, and aluminum . This precision grinding allows for accurate and precise countersink holes
【Efficient Design】Each countersink drill bit is engineered with five blades, which effectively reduces vibration and extends the service life of the bits. This design also enhances chip evacuation, resulting in smoother and more efficient drilling
【1/4" Hex Shank】These countersink bits feature a 1/4" hex shank, making them compatible with all types of drill bits and mold grinders. They are easy to control with a variable speed drill, allowing for a maximum speed of 6000 rpm. When drilling holes in hard materials, it is recommended to use cutting fluid or water to keep the drill bit cool and promote clean cutting. This helps extend the drill bit's life and maintains its sharpness
