Cobalt Drill Bits Set for Hardened Metal, Cast Iron, Stainless Steel, Plastic and Wood

The GMTOOLS brand offers a comprehensive range of high-quality drilling solutions, including the Cobalt Drill Bit Set, Hole Saw Kit, and Tap and Die Set. The Cobalt Drill Bit Set, in particular, is a standout product that provides unparalleled performance and durability.

The GMTOOLS Twist Drill Bit Set is designed with precision and efficiency in mind. Crafted from M35 high-speed steel (HSS) with 5% cobalt content, these drill bits offer enhanced wear resistance and durability, outperforming the standard 4241 HSS used in many similar drill bit sets.

The 135-degree split point and twist design of these drill bits ensure they are automatically centered, reducing walking and penetrating quickly with less pressure. The spiral flute configuration enables efficient chip removal, resulting in a cleaner and more precise drilling experience.

The set includes 13 drill bits, ranging from 1/16" (1.59mm) to 1/4" (6.35mm) in inch/metric diameters, providing a versatile solution for a wide range of applications. Whether you're working with stainless steel, cast iron, aluminum alloy, copper, plastic, or wood, these cobalt drill bits are up to the task.

In addition to the Cobalt Drill Bit Set, GMTOOLS offers a comprehensive selection of drilling accessories, including the Hole Saw Kit, Titanium Coated Twist Hex Shank Drill Bit Set, Auger Drill Bit Set for Wood, and the 99 Pcs Drill Bit Set.

The Hole Saw Kit, for instance, features a range of hole saws in various sizes, from 3/4" to 5", making it ideal for cutting precise openings in different materials. The 10 Pcs 1/8" Titanium Coated Twist Hex Shank Drill Bit Set, on the other hand, offers exceptional performance and corrosion resistance for metalworking applications.
