Product Description

Please look for the Luomorgo brand. We take every customer seriously and provide our customers with the most cost-effective products responsibly! Specification: Cutting Hole Diameter: 5.1" / 130mm Cutting Depth: 1.1" / 28mm Shank Diameter: 0.35" / 9mm Shank Height: 1" / 26mm High Quality Material: Iron alloy Package Includes: 1 x 5.1 inch diamond hole saw How to Cut Successfully: 1. Make a half-moon-shaped notch on the glass/tile/stone drill with 45 degrees. 2. Slowly raise the drill bit to 60 degrees, and then lightly drill. 3. Reach 90 degrees and continue drilling. 4. Finally, the glass/brick/stone is drilled. This technique requires the drill bit to "shake" instead of applying steady pressure all the time. Warm Tips: 1. Please add water as coolant and drill slowly. 2. Start drilling the surface at an angle of 45 degrees and align 90 degrees when forming the hole. 3. Never use an electric drill when the machine is in a hammering state. 4. The hole does not need to be laborious, because the cutting is clean.
