uxcell 100mm Diamond Coated Glass Hole Saw Drill Bits for Ceramic Tile Marble Rock Porcelain Bottles Pots Brick

Description:Cutting tip with AAA Grade diamond particles coated offers sharp cutting, the efficiency of cutting will be improved greatly.Nickel plated. make it more durable than the general hole saw,segmented design works better and lasts longer.Specifically for glass openings.excellent results in and tile.Cut holes smoothly, tidily, with out broken edges and vibration phenomenon.Small incision resistance, increase the speed of cutting holes, easy to decorate after grooving and easy to clean.Attentions:This glass hole saw needs to be used at a low speed, about 800-1000r per minute.In order to prolong the life of this glass hole saw, when processing, please add into coolant liquids or water.Working without cooling is forbidden.Please start your hole diagonally, make a round trace and then hold drill straight.

• SIZE - 100mm(4-inch) Drilling Diameter, 10mm(0.4-inch) Shank Diameter. The hole saw achieves high precision and smooth cuts without edge breakage, with good toughness and high strength.
• DIAMOND COATED - Diamond coating enhances the drilling speed, which makes the bit more sharp.Electroplated diamond is uniform and more wear-resistant.
• NICKEL PLATED SURFACE - Nickel plating surface can extend the service life and enhance the surface corrosion resistance. Diamond coating maximizes performance and retains a sharper cutting edge than traditional carbide or bimetal hole saws.
• SPECIAL DESIGN - The diamond hole saw with clearance hole facilitates the entry of cooling water and the escape of chips from the drilled hole. Makes the drilling process easier. Not suitable for drilling tempered glass, plastic and wood.
• APPLICATIONS - Perfect for drilling glass, ceramics, porcelain, ceramic tile, porcelain tile, limestone, slate, marble, light stone and fiberglass. (Need to be used at a low speed; Always use lubrication (water) when processing, otherwise the hole saw will burn.)
