KWB 209610 HSS Twist Drill Bit Set, 1 mm, 2 Pieces

The KWB 209610 HSS Twist Drill Bit Set consists of two high-performance drill bits, each with a 1 mm diameter. These tools are manufactured from high-speed steel and are designed to meet the requirements of both professional tradespeople and DIY enthusiasts. With a standard type N geometry and a 118-degree tip angle, these bits provide efficient material removal and consistent drilling performance in various applications.

Advantages

These drill bits are roll-forged and steam-hardened, which significantly enhances their durability and resistance to wear during operation. The blue-black surface finish helps to reduce friction and heat buildup, ensuring a longer service life. Their precise construction according to DIN 338 standards guarantees compatibility with standard drill chucks, while the right-hand cutting design ensures smooth and accurate hole creation in a variety of materials.

Suitable for

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

When it may not be suitable

These 1 mm drill bits are extremely thin and fragile, making them unsuitable for heavy-duty drilling in thick or hardened steel plates where high torque could cause the bit to snap. They are also not intended for use with masonry, concrete, or stone materials.

Key specifications

• Diameter: 1 mm
• Material: High-speed steel (HSS)
• Tip angle: 118 degrees
• Standard: DIN 338
• Design: Type N, right-hand cut
• Finish: Steam hardened, blue-black

How to use

Insert the drill bit into a compatible drill chuck, ensuring it is tightened securely to prevent slippage. Align the tip of the bit precisely with the marked center point on your workpiece. Apply steady, light pressure while maintaining a consistent rotation speed. It is recommended to use a drill stand or a steady hand to avoid lateral movement, as the small diameter of the bit makes it susceptible to bending or breaking if subjected to excessive side force.

What to consider before purchase

• Verify that your drill chuck can securely hold a 1 mm shank diameter.
• Ensure the material you are drilling is properly clamped to prevent vibration.
• Consider using a cutting oil to extend the life of the bit when working with metals.

Usage recommendations

Always wear appropriate eye protection when drilling and ensure the workpiece is firmly secured to a stable surface to prevent accidents and ensure clean, accurate results.
