Core Drill Bits: Drilling diameter: 16mm / 0.63"; hex shank size: 1/4"; working depth (max .): 43mm / 1.69"; total length: 73mm / 2.87". Provide high efficiency, fast and smooth drilling, but also ensure longer working life. Wide Applications: Suitable for drilling porcelain, tile, marble, stone, masonry, brick, glass. Can be dry or wet use. It is recommended to be used with water for cooling and lubrication to prolong the using life and increase the performance. Sintered Diamond: Diamond grains are permanently sintered to the cutting edge from inside to outside. Sintered diamond has the sharpening property but electroplated or brazed diamond can not be sharpened. Features: Large clearance hole facilitates entrance of cooling water and escape of chips and other particles from drilling. Creates a precision and smooth cut, less chipping and minimizing breakage. 1/4 Inch Hex Shank: Quick change 1/4 inch hex shank can be used on power tools more easily and securely. Fits most bench drills, hand electric drills. Tips: Reduced drill speeds, low drill pressure and increased use of water lubrication will extend drill bit life considerably. Specifications:
