## Long description

The KWB 209642 HSS twist drill bit is a precision-engineered tool designed for reliable performance in various drilling applications. With a diameter of 4.2 mm and a total length of 75 mm, this drill bit is manufactured according to the DIN 338 standard, ensuring compatibility with standard drill chucks. Its robust construction and steam-hardened surface make it a dependable choice for both professional tradespeople and DIY enthusiasts who require clean, accurate holes in metal and other materials.
Advantages
This drill bit offers exceptional durability due to its roll-forged, steam-hardened steel construction, which provides increased resistance to wear and heat during operation. The 118-degree tip angle is optimized for effective centering and material penetration, reducing the risk of wandering on the workpiece surface. Its design ensures efficient chip removal, which helps maintain drilling speed and prolongs the life of the tool even when working with tougher materials like alloyed steel.
Suitable for
Drilling into alloyed and mild steel
Working with non-ferrous metals
Processing hard plastics
Drilling through sheet metal and profiles
General workshop and maintenance tasks
When it may not be suitable
This drill bit is not intended for drilling into masonry, concrete, or hardened stone, as the HSS material is not designed to withstand the impact or abrasive nature of these surfaces. Additionally, it may not be suitable for extremely deep hole drilling where specialized long-series bits are required for chip evacuation.
Key specifications
Diameter: 4.2 mm
Total length: 75 mm
Standard: DIN 338
Material: High-Speed Steel (HSS)
Tip angle: 118 degrees
Shank type: Cylindrical
Rotation: Right-hand cut
How to use
To use the KWB 209642 drill bit, insert the cylindrical shank securely into the chuck of your power drill or drill press, ensuring it is tightened properly to prevent slippage. Mark your drilling point clearly to ensure accuracy. Begin drilling at a moderate speed, applying steady, controlled pressure. For metal applications, it is recommended to use a suitable cutting oil to reduce friction and heat, which will significantly extend the service life of the bit and improve the quality of the hole.
What to consider before purchase
Verify that your drill chuck supports a 4.2 mm cylindrical shank.
Ensure the material you are drilling is compatible with HSS bits.
Consider using a center punch to prevent the bit from sliding on smooth metal surfaces.
Check if the required hole depth is within the effective length of the drill bit.
Usage recommendations
Always wear appropriate eye protection when drilling. Maintain a consistent feed rate and avoid excessive lateral pressure, which can cause the drill bit to snap. If the bit becomes hot during use, allow it to cool down before handling.
