Product Information
- Premium Material: The masonry drill bits set is made of solid alloy steel with anti-rust and fine polished treatment, and the new electroplating process can prevent the drill bit from rusting and prolong the life of the drill bit.
- Inventive Design: The masonry drill bits for concrete with cemented carbide tungsten cross-heads, which is harder than ordinary drill bits, increases wear resistance, durability, and an extra long life span, so that the drill bits can be used repeatedly.
- Exquisite Craftsmanship: The carbide tile cement drill bits are sharper, has a double design of cross arrow and spiral groove, precise positioning, easy chip removal, decreases friction and heat for faster drilling performance, and is easy to penetrate various materials.
- Convenient to Operate: 1/4"hex handle which makes the electric drill more tight and not easy to slip, making it safer to use, is tighter than the round-handled glass and tile drill bit suitable for all electric drills, hand drills, and bench drills. It fits more easily and locks into the quick-change chuck.
- Package Contents: 10 pieces of fine-grade, high-durability masonry concrete drill bits about 2.9–3.7 inches in length : 5/16" (8 mm) bit (4 pieces); 3/8" (10 mm) bit (3 pieces); 1/2" (8 mm) bit (3 pieces). That will help in drilling by starting with the smallest bit and continuing to the size needed.
