It provides excellent heat resistance, durability, and precise hole drilling, making it an essential choice for professional metalworking and industrial applications.

## Long description

The Fanar NWKA 4.10mm twist drill bit is a high-performance cutting tool engineered for demanding metalworking tasks. Manufactured from HSSE cobalt-alloyed high-speed steel and finished with a durable TiN (Titanium Nitride) coating, this drill bit is built to withstand the rigorous conditions of industrial machining. It adheres to the DIN 338 standard, ensuring compatibility with standard drill chucks and consistent performance in precision drilling operations.
Advantages
The primary benefit of this drill bit lies in its cobalt-alloyed composition, which significantly enhances heat resistance and structural integrity during high-speed drilling. The TiN coating further improves surface hardness and reduces friction, which helps to extend the tool life and maintain sharpness even when working with abrasive or tough materials. This combination of materials ensures that the drill bit maintains its geometry and cutting efficiency over extended periods of use, reducing the need for frequent replacements.
Suitable for
Drilling stainless steel
Machining difficult-to-cut alloys
Professional metalworking and fabrication
Industrial drilling applications
When it may not be suitable
This drill bit is specifically optimized for hard metals and stainless steel. It may not be the most cost-effective choice for drilling soft materials like wood, plastic, or aluminum, where standard high-speed steel bits would suffice.
Key specifications
Diameter: 4.10mm
Material: HSSE cobalt-alloyed high-speed steel
Coating: TiN (Titanium Nitride)
Standard: DIN 338
Application: Stainless steel and difficult-to-cut materials
How to use
To achieve optimal results, ensure the drill bit is securely fastened in a stable drill press or a high-quality hand drill. Use appropriate cutting speeds and feed rates suitable for the material being drilled to prevent overheating. It is recommended to use a suitable cutting fluid or lubricant to reduce friction and dissipate heat, which will further protect the TiN coating and the cutting edge of the drill bit.
What to consider before purchase
Verify the required hole diameter for your specific application
Ensure your drilling equipment supports the DIN 338 shank size
Assess the hardness of the material to confirm if HSSE is necessary
Usage recommendations
Always wear appropriate eye protection and ensure the workpiece is firmly clamped before starting the drilling process to maintain safety and precision.
