Specification Brand : HARFINGTON BulletPoint1 : Size - Drilling diameter: 5mm / 3/16"; hex shank: 6.35mm / 1/4"; drilling length: 45mm / 1.77"; total length: 75mm / 2.95"; 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. BulletPoint6 : Versatile Application: Suitable drilling for a variety of applications, including masonry projects, construction tasks, and home improvement projects. This drill bit is designed to tackle a wide range of materials with ease BulletPoint7 : Compatibility: This Drill Bit is designed to work with drills/hammer drills or rotary hammer drills, this drill bit ensures optimal results when paired with the right equipment Color : Black CuttingAngleString : 130.0 degrees ExternallyAssignedProductIdentifier : 7000164110792 FinishType : Chrome Platd GpsrSafetyAttestation : 1 ItemName : HARFINGTON 12pcs Concrete Masonry Drill Bits 5mm (3/16") Tungsten Carbide Tip Chrome Plated Triangle Cross Drill Bit for Ceramic Tile Brick Glass Plastic Wood, Black ItemPackageDimensions_Height : 9.3 centimeters ItemPackageDimensions_Length : 1.5 centimeters ItemPackageDimensions_Width : 6 centimeters ItemPackageQuantity : 10 ItemShape : Round ItemTypeKeyword : masonry-drill-bit-sets Manufacturer : HARFINGTON Material : Tungsten Carbide Tip, Carbon Steel Body Material1 : Chrome Vanadium Steel Material2 : High Carbon Steel ModelName : Fafeicyzwicp5nkgt ModelNumber : Fafeicyzwicp5nkgt NumberOfFlutes : 2 NumberOfItems : 10 PartNumber : hta231124hh000655 ProductDescription : 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. 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.
