Solid Carbide Drill Bits for Hardened Steel

Carbide twist drills offer excellent wear resistance and are designed specifically for drilling in hard materials such as hardened steel. Their unique geometry and coating technology effectively reduce cutting heat and optimize chip evacuation, thereby increasing machining efficiency and extending tool life. This series of drills is not only suitable for standard drilling operations but also for applications requiring high precision and surface quality, ensuring outstanding performance even in extreme working conditions.

Suitable for Drilling hardened steel

Large core thickness, small helix angle, high rigidity, and strength

X-shaped Drills tip, excellent self-centering capability

Radius Drills point, contributes to excellent hole-wall quality

The GEM-D998-Y3N series of carbide twist drills ranges in size from 4mm to 16mm and is suitable for drilling with external cooling. With a maximum drilling depth of 3D, this series of drills meets medium-depth drilling requirements. Users can choose this model for efficient drilling of hardened steel and other high-hardness materials.

The GEM-D998-Y3N series carbide twist drills are suitable for machining a wide range of metal materials, particularly hardened steel (45-60 HRC), common steels, and stainless steels. By referring to this material compatibility chart, users can more accurately select drill bits to ensure optimal performance and results in machining different hardnesses and materials.
