1.Serrated Design: diamond hole saw has saw-shaped teeth on the top to ensure sharp teeth and fast drilling speed. The openings between the sawteeth are neat, and there are multiple chip removal grooves, which can quickly discharge dust during the drilling process and is not easy to block, thus improving the work efficiency 2.Wide Application: The core bit set is designed for Drilling a hole or Milling Bevelling, Enlarging, Grinding to porcelain tiles, ceramics, marble, granite, etc., one set can meet almost needs in daily life 3.What you got: 12pcs Sets: 6mm(1/4"),6mm(1/4"), 8mm(5/16"),20mm(4/5"),25mm(1"),35mm(1-3/8"), 50mm(2"), 75mm(3"),100mm(4") hole saw; 20mm(4/5")milling bits,1pc 50mm(2")chamfer bits; 5/8"-11 thread; and 1pc sdsplus to 5/8"-11 adapter;1pc EVA positioner and 1pc hard storage bag 4.Advanced technology: All brazed hole saws are treated by a special high-temperature resistant process. they can withstand the huge heat generated by the hole saw when it rotates at high speed. Water can be an additional coolant to extend the service life. Vacuum brazed technology provides excellent drilling strength for high-precision and smooth cutting, and the drilling is stable and fast 5.EVA Mold Precise Positioner: The tile drill guide jig is made of high-density vinyl acetate copolymer, which has the effect of forming beads when meeting water. It is impervious to water and has an excellent waterproof effect. It can effectively fix the drill position of the hole saw. The precise positioning system firmly clamps the hole saw to prevent sliding and object damage caused by improper operation ABOUT PRODUCTION:
