• PRECISE POSITIONING & ANTI-WALK DESIGN：The included detachable centering pilot drill locks firmly onto marked spots, preventing wandering or slipping on smooth surfaces like glass and ceramic tile. Once positioned, remove the pilot bit and continue with a slight wobbling motion for a clean, precise hole every time.
• VERSATILE MULTI-MATERIAL CUTTING：Engineered to drill clean holes through a wide range of hard, brittle materials—porcelain tile, ceramic, granite, marble, stone, glass. Whether installing faucets and garbage disposal buttons on countertops, fitting pipes and shower fixtures, or tackling bathroom remodels, HVAC work, and planter drainage holes, this hole saw set handles it all with ease.
• LONG-LASTING & HEAT-DISSIPATING：Crafted from high-carbon steel with advanced vacuum brazing, high-quality diamond grit is firmly bonded to the cutting edge for superior hardness, exceptional wear resistance, rust resistance, and extended service life. The hollow body with U-shaped grooves speeds up debris removal and heat dissipation, preventing burnout. Triangular 3/8" shank ensures a secure, non-slip grip for safer operation.
• MAXIMUM CUTTING DEPTH, MULTIPLE SIZES & KIT CONTENTS：Each diamond hole saw offers a maximum cutting depth of 1-3/16" (30mm), ideal for thicker countertops, tiles, and pipe installations. Multiple diameter options are available to match your specific project. Every set includes one diamond core drill bit (in your selected size), one guiding pilot drill bit, and one hex wrench, all neatly packed in a storage box for easy access.
• DRY & WET DRILLING – WET USE EXTENDS LIFE ：Engineered for both dry and wet drilling. Dry cutting offers speed and convenience. For wet cutting, simply dip the bit in water at regular intervals or use water as a lubricant to reduce heat and friction. This water-cooling method ensures smoother, cleaner cuts while helping extend the bit's service life.
