Twist drill bit KWB 248080 1 pc Right hand rotation

The KWB 248080 HSS-Co twist drill bit is a high-performance tool engineered for precision drilling in a wide range of demanding materials. Featuring a 5% cobalt alloy composition, this drill bit offers enhanced heat resistance and durability, making it an ideal choice for professional and DIY metalworking applications. Its design adheres to the DIN 338 standard, ensuring consistent quality and performance for various drilling tasks.

The primary advantage of this drill bit lies in its specialized 135° point angle with a split point according to DIN 1412 C. This geometry provides excellent self-centering capabilities, which significantly reduces the risk of the bit slipping on the workpiece surface. The right-hand cutting type N design, combined with a parallel shank, ensures universal compatibility with standard drilling machines, allowing for efficient and accurate hole creation in both alloyed and unalloyed metals.

Suitable for

• Drilling in stainless steel (V2A/V4A)
• Working with alloyed and unalloyed steel
• Processing grey cast iron and cast steel
• Drilling in bronze and various plastics

When it may not be suitable

This drill bit is specifically optimized for metal and hard plastic applications. It may not be the most efficient choice for drilling in soft woods or masonry, where specialized wood or concrete bits would provide better results and prevent clogging or overheating.

Key specifications

• Material: HSS-Co (5% cobalt alloy)
• Standard: DIN 338
• Point angle: 135° with split point (DIN 1412 C)
• Cutting direction: Right-hand
• Shank type: Parallel

How to use

To use the KWB twist drill bit, insert the parallel shank securely into the chuck of your drilling machine, ensuring it is tightened properly. Mark the center of the hole to be drilled to assist with the self-centering feature. Apply steady, moderate pressure while maintaining a consistent speed appropriate for the material being drilled. It is recommended to use a suitable cutting oil when working with metals to extend 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 project
• Ensure your drill machine chuck is compatible with a parallel shank
• Consider using cooling lubricants for harder materials

Usage recommendations

For optimal performance and to prevent premature wear, always maintain a steady feed rate and avoid excessive lateral pressure during the drilling process.
