Cobalt Drill Bit Set 29-Piece M35 Cobalt Steel Drill Bits for Steel, Wood, Plastic, and Sheet Metal

From the brand CaRoller Tools, our story begins with a relentless pursuit of perfection in tools, offering users an unmatched work experience. Innovation is at the heart of everything we do, from our Cobalt Drill Bit Set to our Oscillating Saw Blades and Tungsten Carbide Burr Set.

As seasoned Amazon operators, we specialize in delivering top-notch drill bit sets and oscillating tool blades. In our factory, every tool undergoes meticicular design and manufacturing, employing advanced production techniques alongside traditional craftsmanship to ensure each product meets the highest standards. From material selection to stringent production control, we maintain strict quality control.

The CaRoller 29-piece drill bits set contains 29 cobalt steel drill bits with gold oxide. A self-centering 135-degree split point penetrates hard material without a pilot hole and produces smaller chips that reduce clogging compared to a 118-degree point. Cobalt steel provides extended tool life compared to high-speed steel drill bits, and maintains the tool's toughness and hardness in high drilling temperatures.

A gold oxide finish acts as a lubricant and provides wear resistance, and the round shank accommodates most drill chucks. The 135° split point with round straight shank is self-centering, preventing walking and making drilling precise and faster. The fully ground twist design helps clear particles faster, decreasing friction and heat for a cooler drilling performance.

With titanium coating for capability and durability, the cutting edge is hardened and honed for sharpness. The chatter-free design with staggered cutting teeth ensures precise countersinking and smooth holes. The M35 Cobalt High Speed Steel is more suitable for tough, high tensile strength material, particularly successful in cutting hardened metals such as stainless steel, cast iron, high temperature alloy, titanium alloy, hard plastics and woods, and it also can be used for softer materials.

The set includes bit sizes from 1/16" to 1/2" in 1/64" increments, making it a must-have for professionals, woodworkers, handymen, construction workers, and DIY enthusiasts. The heavy-duty construction with HSS cobalt durable material and amber coating ensures long-lasting use and superior wear resistance.

The ergonomic and portable cup-type round carrying case with built-in clip allows you to easily attach the drill bit set to your tool belt, keeping your bits within immediate reach and preventing constant loss or misplacement. The versatile functions of this cobalt drill bit set make it an excellent choice for a wide variety of materials and applications.
