Special Features
【Superior Coating, Smoother Experience】 This product features a TiAlN coating with outstanding high-temperature stability and oxidation resistance, enduring up to 1400°F. With a lower friction coefficient than most conventional coatings, it effectively reduces friction, heat buildup and workpiece adhesion. It is especially suitable for machining sticky materials including stainless steel, titanium alloys and superalloys, while improving chip evacuation. This reduces edge chipping and wear, delivering a 5x longer service life.
【M35 Cobalt Material, High-Efficiency Drilling for Hard Metals】 Crafted from premium M35 high-speed steel with 5% cobalt addition, this drill bit delivers exceptional red hardness, wear resistance, and heat resistance. Engineered for high-intensity drilling applications, it effortlessly cuts through stainless steel and various hardened metals. Maintaining stable cutting performance during high-speed operations, it significantly extends tool lifespan, making it an ideal choice for industrial processing and mechanical maintenance.
【From Top To Bottom, Built For Fast Drilling】 The 135°multi-flute drill bit features a split point design that ensures perfect self-centering, prevents bit runout, and enables fast drilling. The double-helix flutes facilitate efficient chip evacuation, and the short-shank design—with lengths ranging from just 1.79 to 2.34 inches—allows easy access to hard-to-reach, confined spaces. Sizes include 3/32"x1, 1/8"x2, 3/16"x1, 1/4"x2, 5/16"x1 and 3/8"x1, offering a wide range of options for one-stop purchasing.
【One Box, Multiple Sizes】 Each drill bit set includes a variety of sizes. In addition to standard sizes, we also offer smaller-sized drill bits. This one-stop solution covers the size requirements for a wide range of applications. Hex shank design provides a more stable grip and fits most common tools such as right-angle adapters, impact drills and electric drills. It allows fast installation and removal, saving time and effort.
【Separate Storage Box, Easy To Carry】 The box keeps your drill bits neatly organized and ready to use whenever you need them. It's easy to carry, making it convenient for storage whether at a fixed workstation or on the go, and helps prevent loss or scattering. We're here to ensure a smooth shopping experience for you.
