Specification Brand : HARFINGTON BulletPoint1 : Size - Drilling diameter: 3mm / 1/8", 4mm / 5/32", 5mm / 3/16", 6mm / 1/4", 8mm / 5/16"; hex shank: 6.35mm / 1/4"; type: cross angle head. (1/4" hex shank installs easier and more securely into all power tools. Can be used with universal hand drills and bench drills.) BulletPoint2 : 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. BulletPoint3 : 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. BulletPoint4 : 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. BulletPoint5 : 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.

Small incision resistance, accurate and easy drilling. The carbide tip ensures long-lasting sharpness and increased drilling efficiency. Black chrome plating enhances corrosion resistance, extends service life and prevents rust. 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. The drill bits are versatile tools designed for drilling holes in a variety of materials including concrete, masonry, bricks, glass, tiles, marble and stone, plastic, and wood. Not suitable for metals. Make sure there are no steel bars or other metal objects before drilling. 1/4" hex shank installs easier and more securely into all power tools. It can be used with universal hand drills and bench drills. The hex shank design prevents slipping during drilling, ensuring improved control and power transmission. Notice: 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. Apply steady and consistent pressure while drilling. Always wear appropriate personal protective equipment.
