Product Highlights

High-Speed Steel for Maximum Durability
Forged from M2 HSS with a hardness of HRC 62-65, it offers exceptional heat and impact resistance, enabling high-speed drilling and lasting 3-5 times longer than standard bits.

Nitriding Coating for Wear Resistance
The black nitride surface coating reduces friction and heat buildup, preventing chipping and wear, ensuring stable performance even on tough materials like stainless steel.

Optimized Flute Design for Efficient Chip Removal
The precision-engineered helix angle and flutes ensure smooth chip evacuation, avoiding clogging and overheating for consistent, reliable drilling.

Precision Tip for Accurate, Clean Holes
The precision-ground tip ensures perfect centering and minimal wandering, producing smooth, burr-free holes that require no secondary finishing.

Versatile Compatibility with Multiple Materials
Ideal for drilling through stainless steel, carbon steel, copper, aluminum, plastic, and more, suitable for machining, automotive repair, DIY projects, and construction.

Industrial-Grade Quality at an Affordable Price
Manufactured to strict industrial standards and tested for wear resistance and precision, these bits deliver professional results at a cost-effective price.
