Special HSS-CO drill bit for high-performance stainless steel COFAN

The high-performance stainless steel drill bits are ground with 5% cobalt. HSS CO DIN 338N 135º. For steel and stainless steels. Bright silver color COFAN represents an indispensable tool for professionals and DIY enthusiasts seeking superior performance when drilling stainless steel.

Manufactured with high-quality materials and complying with the strict DIN 338N standards, these drill bits offer a series of advantages that make them the ideal choice for demanding work in this complex material.

FEATURES

- Cobalt high-speed steel (HSS-CO): The drill bits are made from cobalt high-speed steel (HSS-CO), an alloy of high-speed steel 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 drill bits feature a precision sharp tip that ensures a clean and precise entry into the material, minimizing chipping and deviation, which is especially important in hard materials like stainless steel.

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

- Deep helical flutes with optimized angle: The deep helical flutes of the drill bits 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 drill bits 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 ensures precise, efficient drilling with a clean finish in stainless steel.

Less user fatigue: The ergonomic design of the shank 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.

Long lifespan: The robust construction of the drill bits with cobalt high-speed steel and high-precision grinding ensures a long lifespan even in demanding drilling applications in stainless steel.
