4pcs Concrete Masonry Drill Bits 16mm (5/8") Tungsten Carbide Tip Chrome Plated Long Triangle Cross Drill Bit for Ceramic Tile Brick Glass Plastic Wood, Black

Size - Drilling diameter: 16mm / 5/8"; hex shank: 8.8mm / 11/32"; drilling length: 95mm / 3.74"; total length: 150mm / 5.91"; type: cross angle head. (Hex shank installs easier and more securely into all power tools. Can be used with universal hand drills and bench drills.)
Material - Masonry drill bits with tungsten carbide tips are harder, more durable, and more wear-resistant than ordinary drill bits. Small incision resistance, accurate and easy drilling. Black chrome plating enhances corrosion resistance, extends service life and prevents rust.
Feature - Cross angle tip helps provide an efficient cutting action in masonry materials like concrete, brick and stone. The cross angle tip enhances the drilling speed and performance by reducing resistance and minimizing bit walking. U groove design for quick drilling and dust removal.
Applications - The drill bits are versatile tools designed for drilling holes in concrete, masonry, bricks, glass, ceramic tiles, marble, stone, tile walls, glass mirrors, plastic and wood. Not suitable for metals. Make sure there are no steel bars or other metal objects before drilling.
Notes - Please keep the drill bit vertical and use cooling water or coolant to lubricate and cool the cutting edge. Start drilling at a slow speed and gradually increase the speed to achieve an efficient drilling progress. Always wear appropriate personal protective equipment.
