Special Features
6 Sizes of Concrete Drill Bit Set: 17-piece concrete drill bit kit comes with a bit holder and keychain. The set includes 6 different sizes: 1/2"×1, 5/16"×1, 3/8"×1, 1/4"×2, 3/16"×2 and 5/32"×1. It is perfect for household DIY projects and drilling tasks across various materials.
High-quality Materials: This masonry drill bit is made with premium NF10X tungsten steel tip, ensuring long-lasting durability and wear resistance. The sharp cutting edge can easily cut through various materials. The Shockproof design ensures stable, accurate drilling, especially in hammer mode.
Upgraded Double U-Shaped Groove Design: These grooves quickly channel debris up and out of the hole. This rapid material removal prevents buildup between the bit and the hole wall, reduces friction heat, and minimizes the risk of bit binding. The 1/4" double-groove hex shank ensures a secure grip in the drill chuck, eliminating wobble and "walking" for accurate drilling.
Portable Design: Equipped with bit holder and keyring for tidy, organized storage. Its compact and lightweight design allows you to easily clip it to tool belt, tool bags, or backpacks, ensuring your drill bits are always within reach. Whether working at heights or on outdoor repairs, it's easy to carry and adapts to multiple scenarios.
Multi-Purpose for Diverse Materials: The carbide hex shank drill bit is engineered to drill through concrete, brick, glass, ceramic, tile, cement, stainless steel plate (thickness<2mm) and more. Keeping the drill bit cool with water while drilling helps extend bit life.
