HSS M35 4-Flute Step Drill Bit with TiAlN Coating
The HSS M35 4-Flute Step Drill Bit with TiAlN Coating is a high-performance cutting tool made from cobalt-alloyed high-speed steel (5% Co), known for its superior hardness and heat resistance. The M35 material allows the drill bit to maintain strength and sharpness even when working with tough materials such as stainless steel, titanium alloys, and cast iron. Its 4-flute design ensures smoother cutting, faster chip removal, and improved hole accuracy compared to standard step drills.



The drill bit is enhanced with a TiAlN (Titanium Aluminum Nitride) coating, which significantly boosts its durability and performance. This advanced coating provides excellent thermal stability, reduces friction, and prevents oxidation under high temperatures, making it ideal for high-speed or dry machining operations. The result is a longer tool life, reduced downtime, and consistently clean finishes even in demanding production environments.
With its multi-step geometry, this tool is capable of drilling, chamfering, and deburring in a single pass—saving time and improving efficiency. It's widely used in sheet metal fabrication, electrical panel work, automotive parts, and CNC machining. Whether for manual or automated drilling, the HSS M35 4-Flute Step Drill delivers reliable, precise performance across a range of metalworking applications.
