The M35 Cobalt 4-Flute Step Drill Bit is a professional-grade industrial tool engineered for precision drilling through the toughest materials. Crafted from high-speed steel infused with 5% Cobalt (M35), this bit is specifically designed to handle stainless steel, cast iron, and hardened alloys that would quickly dull standard bits.
The addition of cobalt provides exceptional heat resistance, ensuring the cutting edges stay sharp even during high-friction operations. What sets the M35 Cobalt 4-Flute Step Drill Bit apart is its innovative 4-flute geometry. Unlike traditional single or double-flute bits, the four-flute design distributes the cutting load more evenly, resulting in significantly faster penetration and a much smoother finish. This design also facilitates superior chip evacuation, which prevents clogging and reduces the risk of overheating the workpiece. Whether you are an HVAC professional, an automotive technician, or a serious DIYer, this tool provides the efficiency required for demanding projects.
Investing in an M35 Cobalt 4-Flute Step Drill Bit means you can replace an entire set of individual drill bits with one versatile tool. The stepped increments are laser-etched for permanent visibility, allowing you to drill multiple hole sizes without stopping to change bits. The hex shank design ensures a secure fit in high-torque impact drivers and standard drills, preventing slippage during heavy-duty use. At Ashland Workshop and Design, we prioritize durability, and this bit is built to provide a long service life under rigorous conditions. To maintain your M35 Cobalt 4-Flute Step Drill Bit, we recommend using cutting fluid or lubricant during operation to further reduce heat and extend the life of the cobalt steel. We invite you to experience the difference that 4-flute technology makes in your workshop. Elevate your drilling precision today with the M35 Cobalt 4-Flute Step Drill Bit—the ultimate solution for hard metal fabrication.
