3PCS Cobalt Step Drill Bit Set

The 3PCS Cobalt Step Drill Bit Set is a versatile and high-performance tool designed for precision drilling in various materials. This set includes three spiral flute hex shank drill bits, specifically crafted for stainless steel and other hardworking materials. Each bit is meticulously coated with TiALN, offering exceptional durability and efficiency.

Advanced TiALN Coating

The TiALN coating on these step drill bits provides a combination of high hardness, resistance to oxidation, and strong adhesion. This not only extends the life of the bits but also ensures minimal friction and low thermal conductivity, resulting in smoother and more accurate drilling. The three flutes design further enhances stability and reduces deflection during cutting, doubling the service life compared to standard step drill bits.

Practical Applications and Benefits

This cobalt step drill bit set is an essential tool for home DIY enthusiasts, general builders, and engineers. The M35 cobalt HSS material is ideal for drilling through stainless steel, cast iron, high-temperature alloys, titanium alloys, and even hard plastics and woods. The 1/4" hex shank allows for easy installation on impact drivers and quick changes, eliminating the need for shank spinning in the drill chuck. Whether you're working on a home project or a professional engineering task, this set is a reliable and efficient choice.
