  • HRC93 Tungsten Carbide Alloy — 400+ Holes, Built to Outlast: Made from solid Tungsten Carbide Alloy rated at HRC93 hardness — among the hardest materials used in drill bit construction. Engineered to drill 400+ holes through full-porcelain tile without significant dulling, and significantly outperforms standard HSS or basic carbide-tipped bits on granite, marble, vitrified tile, and glass.meaning fewer bit replacements mid-project and lower cost per hole for DIY home repairs
  • 4-Cutter Eccentric Tip — No Walking, 60% Sharper, Cleaner Starts: The eccentric tip grips the surface on contact, eliminating bit wander without tape or center-punching. Four cutting edges — sharpened to a 60% higher cutting angle than conventional tile bits — bite into hard surfaces faster, with less vibration and reduced surface chipping at the start of every hole
  • 5-Step Profile, Drills 2× Faster — One Bit, Five Sizes: Stepped cutting profile covers five sizes:1/4",1/4",5/16",3/8",1/2" (6/6/8/10/12mm) with both metric and imperial markings — eliminating the need to swap bits mid-job. Apply light downward pressure and let the carbide steps do the work: this design cuts up to 2× faster than conventional tile drill bits, with the stepped edges guiding the hole open progressively for rounder, cleaner results
  • Dry or Wet — Know Your Material, Get the Best Result: Dry drilling (no water needed): Regular ceramic tile, antique tile, foam brick, red brick, aerated concrete block, wood, plastic — apply steady light pressure, no coolant required. Wet drilling (add water): Vitrified tile, full-porcelain tile, marble, glass, granite, natural stone, slate — drizzle water at the drill point to reduce heat and protect both the bit and surface. Standard drill only — do NOT use hammer/impact mode
  • Home DIY Ready — Bathroom, Kitchen, Walls & More: Designed for homeowners and DIY enthusiasts: drill anchor holes, mount bathroom fixtures, install kitchen backsplash hardware, hang wall brackets, and tackle tile, concrete, wood, or plastic surfaces — all with one compact bit set. Five graduated sizes (6–12mm) cover the most common home installation needs without switching tools.Get clean, precise holes the first time — no cracked tiles, no wasted trips to the hardware store
