√PACKING LIST: Hole Saw Diameter: 10mm/25/64"Shank Diameter: 6.6mm/0.26"Cutting Depth: 25mm/0.98"Mesh Count: 60/70Weight: 0.18pound √FEATURE: Glass diamond hole cutters provide precise cutting performance with smooth edge results. Their construction helps maintain surface integrity during operation and offers consistent drilling performance √APPLICATION: Suitable for ordinary glass, ceramic, and ceramic tile. Drilling into materials such as tempered glass, wood, or steel plates is not recommended √NOTE: During drilling, need to add water consistently to maintain cooling. This practice helps prolong the service life of the hole saw and reduces the risk of material damage. Beginning by positioning the tool at a 45° angle, then drill vertically. Using a gentle circular motion may help achieve faster cutting. If the hole saw is equipped with a center drill, use it for initial positioning. In this case, starting at a 45° angle is not necessary
