10PCS Four Edged Serrated Eccentric Drill Bits, 1/4 Hex Shank

• High strength, High hardness: Carbide drill bits are made of high-hardness carbide matarial, with high strength and hardness, providing strong wear resistance and impact resistance, and will not deform or break under high-intensity operation, fast hole entry and accurate positioning，Note！it is recommended to add water for cooling during drilling, which will also increase the drilling speed.
• Four Edged Serrated Eccentric Drill Bits: 4 flute drill bits adopt a four-edged serrated eccentric drill bit design, staggered edges form a special cutting trajectory, the drilling process is clean and precise, reducing friction while greatly reducing the possibility of slipping or deflection during the entire drilling process
• Wide chip flute design: The widened chip flute of the masonry drill bits set removes chips smoothly, effectively preventing chip accumulation and retention, high-speed operation and fast drilling speed, and improves the amount of waste chips discharged during high-speed operation
• Hex Shank design: The hex shank design of drill bits for brick walls not only provides a firm grip, but is also compatible with a variety of drill bits. The hexagonal non-slip handle provides long-lasting control, which can significantly enhance its cutting power and precision, achieve maximum efficiency, and save time and energy for all your projects
• Wide application: 2 pcs 5mm, 4 pcs 6mm, 2 pcs 8mm, 1 pcs 10mm, and 1 pcs 12mm, 10 pcs in total, suitable for marble, wood, plastic, cement brick, concrete, red brick, marble, ceramic, and other materials, no matter the size of your task, you can find the right drill bit.

Feature: 【Efficient Chip Removal】Featuring a cross-edge design, this 4-tooth drill bit rapidly disperses material debris during drilling, effectively reducing clogging during operation. This design helps maintain drill bit cooling, ensuring consistent performance during continuous drilling. Experience smoother operation when working with hard, brittle materials like tiles and marble. 【Hard and Wear-Resistant】Crafted from good-quality tungsten carbide, the high strength eccentric drill bit set boasts good hardness and abrasion resistance. It effortlessly handles the smooth surface layer of tiles as well as the hard stone or wood beneath, effectively resisting wear and extending tool lifespan. 【Wide Compatibility】The hexagonal shank design of this drill bit set securely locks into chucks of common cordless drills and impact drivers, preventing slippage. This broad compatibility makes it suitable for most major power tool brands, ensuring effortless use for both professional projects and home repairs.(Do not use lithium-ion drills rated below 24V. When drilling into hard materials, add water to cool the drill bit. Avoid striking rebar during operation.) 【Versatile Applications】The hexagonal shank drill kit not only drills clean holes in tiles and marble without edge chipping but also effectively handles common materials like wood and plastic. This multifunctionality makes it a practical choice for installing kitchen/bath fixtures, home renovations, or woodworking projects.
