KWB 209645 HSS Twist Drill Bit 4.5 mm, DIN 338, Cylindrical Shank

The KWB 209645 HSS twist drill bit is a precision-engineered tool designed for reliable performance in various drilling applications. With a diameter of 4.5 mm and a total length of 80 mm, this drill bit is manufactured to DIN 338 standards, ensuring compatibility and accuracy. Its robust construction and steam-hardened surface treatment provide increased durability and resistance to wear, making it a dependable choice for both professional tradespeople and DIY enthusiasts.

Advantages

This drill bit features a roll-forged design with a 118-degree tip angle, which facilitates efficient centering and smooth penetration into the workpiece. The right-hand cutting action combined with the Type N geometry ensures optimal chip removal, preventing clogging during operation. The blue-black steam-hardened finish enhances the tool's longevity by reducing friction and heat buildup, allowing for consistent results even when working with tougher materials.

Suitable for

• Drilling into alloyed and mild steel
• Working with cast iron and castings
• Processing non-ferrous metals
• Drilling into hard plastics

When it may not be suitable

This drill bit is not intended for use on hardened steel, stainless steel, or masonry and concrete. Attempting to drill into these materials will cause rapid dulling of the cutting edge and potential damage to the tool.

Key specifications

• Diameter: 4.5 mm
• Total length: 80 mm
• Material: High-speed steel (HSS)
• Standard: DIN 338
• Tip angle: 118 degrees
• Shank type: Cylindrical
• Design: Type N, roll forged

How to use

Insert the cylindrical shank of the drill bit into the chuck of your power drill or drill press, ensuring it is tightened securely. Mark the center of the hole to be drilled to prevent the bit from wandering. Apply steady, moderate pressure while maintaining a consistent speed appropriate for the material being drilled. It is recommended to use a cutting oil when drilling into metals to improve performance and extend the life of the drill bit.

What to consider before purchase

• Verify the required hole diameter for your specific project
• Ensure your drill chuck is compatible with a 4.5 mm cylindrical shank
• Check that the material you intend to drill is suitable for HSS bits

Usage recommendations

For best results, maintain a perpendicular angle to the workpiece and clear chips frequently. Using a cooling lubricant is highly recommended when drilling metal to prevent overheating and maintain the sharpness of the cutting edge.
