Diamond Set Auto Eject Spring Cooling Wax Hex Shank For Glass Stone Tile Ceramic Wet Dry Drilling Drill Bit 12Pc

Key Features: Smart Auto-Eject Spring Mechanism Built-in high-tension spring instantly expels debris during drilling, preventing clogging and ensuring smooth, uninterrupted operation. Ideal for deep or continuous drilling in tough materials. Cooling Wax Technology Embedded cooling wax (6/8/10/12/14/16mm sizes) reduces friction heat, extending bit lifespan and enabling effortless dry drilling. Eliminates the need for external cooling in most scenarios. Durable Diamond Grit Construction Industrial-grade diamond segments (15mm width) deliver aggressive cutting for ceramics, porcelain tiles, granite, marble, quartz, and glass. Reinforced bonding resists wear for 10x longer lifespan vs. standard bits. Optimized Chip Removal Oversized discharge holes , high-density hollow design accelerate waste removal for faster, cleaner holes. Beveled edges maintain stability at high RPMs (up to 3,000). Universal Compatibility 1/4" hexagonal shank fits all standard drills (handheld, lithium-ion, or bench-mounted).
