12pcs Concrete Masonry Drill Bits 3mm (1/8") Tungsten Carbide Tip Triangle Drill Bit for Ceramic Tile Brick Glass Plastic Wood, Silver

Size - Drilling diameter: 3mm / 1/8"; hex shank: 6.35mm / 1/4"; drilling length: 42mm / 1.65"; total length: 72mm / 2.83"; type: triangle head. (1/4" 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.
Feature - Triangle angle tip helps provide an efficient cutting action in masonry, concrete, brick and stone. The angle tip enhances the drilling speed and performance by reducing resistance and minimizing bit walking.
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.
