Blister HSS-CO Stainless Steel Drill Bits with 5% Cobalt COFAN

The HSS-CO Stainless Steel Blister Drills with 5% cobalt from COFAN are the ideal tool for professionals and DIY enthusiasts who need superior performance and maximum corrosion resistance when drilling stainless steel.

Manufactured with high-quality cobalt high-speed steel (HSS-CO) and complying with the strict DIN 338N standard, these drills offer a range of advantages that make them the best choice for applications requiring precise and durable drilling in stainless steels.

FEATURES

- Cobalt high-speed steel (HSS-CO): Cobalt high-speed steel (HSS-CO) is a high-speed steel alloy enriched with cobalt that offers exceptional hardness, wear resistance, and heat resistance. Cobalt increases abrasion and temperature resistance, allowing for drilling stainless steel at higher speeds and with greater precision.

- Precision sharp tip: The drills feature a precision sharp tip that ensures a clean and accurate entry into the material, minimizing chipping and deviation, which is especially important in stainless steel where precision is crucial.

- 135° tip angle: The 135° tip angle is specifically designed for efficiently drilling stainless steel, optimizing penetration, chip removal, and reducing torque.

- Deep helical flutes with optimized angle: The deep helical flutes of the drills facilitate the quick and efficient removal of chips, reducing friction and heat during drilling, minimizing drill wear, and improving cooling.

- High-precision grinding: High-precision grinding ensures optimal concentricity and surface finish, resulting in greater accuracy and less vibration during drilling.

- Cylindrical shank: The drills have a cylindrical shank that makes them compatible with a wide range of chucks and drills, including electric, cordless, and column drills.

ADVANTAGES

Precise and efficient drilling in stainless steel: The combination of cobalt high-speed steel, precision sharp tip, 135° tip angle, deep helical flutes, and high-precision grinding guarantees precise, efficient drilling with a clean finish in stainless steel.

Less user fatigue: The ergonomic handle design reduces user fatigue during prolonged drilling.

Faster and cleaner drilling: The deep helical flutes with optimized angle allow for faster and cleaner drilling, minimizing friction and wear.
