• 【Precision Sizes for Standard Anchors】 This 8-piece set includes 4x 1/4" (6mm) diamond drill bits, plus 5/16" (8mm), 3/8" (10mm), and 1/2" (12mm) bits, along with a 1/4" (6mm) carbide-tipped centering bit. The bright yellow finish makes each bit easy to identify at a glance. With sizes covering common installation needs, the set is ready to use right out of the box.
• 【Dry & Wet Drilling, Built to Last】 The bits feature an upgraded C45 high-carbon steel body that combines high hardness with flexural strength, resisting bending and deformation under high pressure and heat for stable, accurate drilling during heavy-duty use. Diamond grit is permanently fused to the steel core through vacuum brazing, delivering up to 3x the durability of standard tile bits while maintaining fast, aggressive cutting speed. A built-in cooling wax core absorbs heat for short dry-drilling tasks.
• 【Vacuum Brazed Construction】 The bright yellow body stands out for quick identification on the job site. The carbide-tipped centering bit keeps the start of each hole on point, preventing slipping and wandering for more precise drilling. The vacuum-brazed diamond layer paired with the C45 steel body balances sharpness, durability, and resistance to deformation — works dry or wet with minimal mess. The multi-size bit combination handles everything from high-frequency small holes to medium and large diameters, so one set covers a wide range of installation tasks.
• 【Kitchen & Bathroom Renovations】 Ideal for kitchen, bathroom, and whole-home renovations. Engineered for porcelain tile, ceramic, pots, planters, glass, granite, masonry, quartz, stone, marble, acrylic, and wall surfaces. Drills clean, precise holes without chipping or cracking — even on the hardest tile grades. A practical choice for home improvement and professional construction projects.
