## Summary description

The KWB COBALT HSS CO twist drill bit is designed for drilling with right hand rotation. It comes in a blister package and is suitable for various materials. This drill bit is known for its durability and precision, making it ideal for professional use.

## Long description

The KWB COBALT HSS CO twist drill bit is a high-performance tool engineered for professional drilling applications requiring right-hand rotation. Featuring a 5% cobalt alloy composition, this precision-ground drill bit offers exceptional heat resistance and durability, making it suitable for demanding industrial tasks. The bronze-colored finish and cross-ground tip design ensure reliable performance and longevity even when working with challenging materials.
Advantages
This drill bit provides superior cutting efficiency due to its 135-degree tip angle, which allows for effective self-centering during operation. The robust cobalt alloy construction maintains its hardness at high temperatures, preventing premature wear and ensuring consistent results. Its precision-ground geometry facilitates clean, accurate holes, reducing the need for secondary finishing and enhancing overall productivity in professional environments.
Suitable for
Drilling into alloyed and unalloyed steel
Working with stainless steel grades A2 and A4
Processing cast iron and cast steel
Drilling into bronze and various plastics
When it may not be suitable
This drill bit is optimized for metalworking and high-strength materials, so it may be less efficient when used on soft wood or masonry, where specialized drill bits would provide better results. It is not intended for use in hammer drill modes.
Key specifications
Material: 5% Cobalt alloyed HSS
Tip angle: 135 degrees
Geometry: Cross-ground to DIN 1412 C
Rotation: Right-hand cut
Design: Cylindrical shank
How to use
To achieve the best results, ensure the drill bit is securely fastened in a compatible drill chuck. Begin by marking the center point of the hole to assist the self-centering tip. Apply steady, moderate pressure while maintaining a consistent speed appropriate for the material being drilled. Using a cutting oil or lubricant is recommended when working with stainless steel or hard alloys to prolong the life of the drill bit and improve the quality of the hole.
What to consider before purchase
Verify the required diameter for your specific application
Ensure your drill chuck is compatible with cylindrical shank bits
Check that your power tool supports the necessary speed settings for cobalt bits
Usage recommendations
Always wear appropriate eye protection and secure the workpiece firmly before starting the drilling process to ensure safety and precision.
