Product description

  • 【Innovative Eccentric Tip & Easy Vertical Drilling】Engineered with an advanced off-center eccentric chisel tip (distinct from standard cross bits) that ensures perfect self-centering.
  • Eliminates bit wandering and skating on glossy surfaces for clean, precise holes. 【1/4" Hex Shank & Power Requirements】 Features a standard 6.35mm (1/4") hex shank for quick, slip-resistant bit changes.
  • Universally compatible with hand drills, bench drills, and cordless impact drivers.
  • Important Note for Cordless Drills: To prevent stalling, a high-torque lithium-ion drill with a power rating higher than 24V is highly recommended. 【Efforless Dry Drilling for Daily Wall Plugs】 Ideal for dry cutting through softer materials.
  • Perfect for drilling installation holes for wall plugs or expansion bolts in wood, plastic (PVC pipes), foam/antique/red bricks, glaze tiles, cement, and concrete (always avoid hitting steel rebar). 【Coolant Required for Ultra-Hard Materials】 For dense, premium materials like vitrified tiles, full-ceramic tiles, porcelain, marble, and glass, you MUST use sufficient water or coolant.
  • This keeps the industrial-grade tungsten carbide head cool, prevents debris clogging, and maximizes the tool's lifespan. 【Versatile Multi-Material & Thin Metal Use】A true all-rounder for household DIY and professional jobs.
  • Beyond masonry and wood, these high-brazed carbide bits are strong enough to cleanly penetrate thin metals, suitable for aluminium, stainless steel, and copper with a thickness under 3mm.
