【NEW DESIGN】: 7 piece drill bit set with 7 different sizes: that is 3mm(2/17”) , 3/16” (5mm),1/4” (6mm), 5/16” (8mm) ,3/8” (10mm), 1/2” (12mm) fit your different needs.
【EXQUISITE CRAFTSMANSHIP】: The surface of the drill bit is treated by fine polishing, and the new electroplating process can prevent the drill bit from rusting and prolong the life of the drill bit.
【 HIGH-QUALITY MATERIALS】: It is made of high quality alloy as raw material. The process of oxynitriding of the cutter head strengthen the drill hardness.
【 NON-SLIP HEX SHANK】: 1/4 hex shank which makes the electric drill more tight and not easy to slip. Making it safer to use.
【WIDELY APPLICATION】: It is suitable for glass, ceramic, wood, brick wall, marble etc. Please try to keep the drill vertical and keep bits cool with a flow of cooling water, don’t use on hard tile.
【High-quality materials】Drill bit is made of high-quality alloy, which keep the hardness and sharpness longer than traditional steel bits, can easily puncture various materials. 【Reinforced U-Type Groove】The cement drill bits have special U groove drill design chip removal smoothly, fast penetration, improve drilling efficiency. 【Hexagonal handle】Hex Shank allows drill bit easy plug and to be held tightly.
