Description of Mgtgbao Ceramic Masonry Carbide Concrete: Top-Notch Type for Superior Concrete Work
❶HIGH-QUALITY HARD ALLOY: The cutter head is made of cemented carbide. Hardness up to 45HRC, Triangular cutter head resistance is smaller. And it can improve work efficiency, higher hardness than ordinary drill bit, more wear-resistant. ❷EXQUISITE 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. ❸15 PCS DRILL BIT SET WITH 6 DIFFERENT SIZES: 5/32” (4mm), 3/16” (5mm),1/4” (6mm), 5/16” (8mm) ,3/8” (10mm), 1/2” (12mm) fit your different needs. ❹NEW DESIGN: U-shaped drain groove, spiral handle design, easy to remove chips during work, smoother drilling. ❺WIDELY USAGE: It can be used for drilling walls, bricks, ceramic, wood, glass, tiles, stainless steel, concrete, etc. Remember to add Water or coolant when drilling.
