- Hard alloy steel material, wear resistance and impact resistance: After heat treatment, the surface can obtain a high temperature, wear resistance and impact resistance, and the hardness and toughness are greatly improved. -Double heliix chip removal, rejecting drill burning: The double heliix effectively prevents chip accumulation and retention, and the high-speed operation is smooth and the efficiency is higher. - Cross four-edged, faster and more neat drilling: fine workmanship, sharper cutting. - Adding water can effectively avoid damage to the drill bit: water drills should be added to materials with higher hardness (note: when drilling continuously, water cooling is required to avoid burning the drill bit and prolong the service life of the drill bit). - Compatible models: screwdrivers, electric drills, rechargeable drills. Kind tips:
01. The torque of rechargeable drills and screwdrivers below 24V is too low, so it is not recommended to use! 02. Drilling of ceramic tile/glass/stone needs to add water to cool down, prolong the service life of the drill bit! 03. When drilling the wall, do not hit the steel bar, otherwise it will cause the cutting edge to collapse!
