Carbide Drill Bits for Stainless Steel

Twist drills excel in drilling stainless steel and other high-temperature resistant materials. Their specialized geometry and coating effectively reduce cutting heat, improve chip evacuation, and ensure stability during high-load machining. These drills are suitable not only for standard drilling operations but also for applications requiring high hole accuracy and surface quality.

Suitable for highly efficient Drilling of stainless steel, carbon steel, alloy steel, heat-resistant alloys, and titanium alloys, etc

Unique bottom edge design–stronger chip breaking capability and larger chip holding space

New substrate coating contributes to superior toughness and wear resistance

Large groove design provides good chip evacuation performance

The detailed specification sheet for carbide drill bits for stainless steel covers various sizes, cooling methods, and drilling depths (L/D ratios). This series offers both external and internal cooling options, along with 3D and 5D drilling depths. Users can select the most appropriate drill bit based on their specific machining conditions and requirements, ensuring optimal results and tool life.

The comparison of the applicability of high-performance steel twist drills in different workpiece materials, covering a variety of materials such as carbon steel, alloy steel, stainless steel, cast iron, aluminum alloy, copper alloy, and heat-resistant alloy, intuitively reflects the advantages of each model of drill in processing different materials.
