## Summary description

FANAR WIERTLO NWKA drill bit, Ø 3.90 mm, HSSE material and ground finish suitable for stainless steel (INOX). Designed to DIN 338 dimensions with usable length/overall length 43/75 mm. Intended for precision drilling in metalworking, toolrooms and workshops where corrosion-resistant alloys and stainless materials are machined.

## Long description

FANAR WIERTLO NWKA Ø3.90 mm HSSE drill bit is engineered for precision drilling in stainless steel and corrosion-resistant alloys. Manufactured from high-speed steel with cobalt (HSSE) and ground to DIN 338 dimensions, this drill bit provides the correct geometry and rigidity for demanding metalworking tasks. The usable length of 43 mm and overall length of 75 mm suit a range of machining set-ups in toolrooms, workshops and production environments where stainless materials require controlled cutting and chip evacuation.
Advantages
This HSSE drill bit offers improved wear resistance and heat tolerance compared with standard high-speed steels, maintaining cutting edges when working with stainless steels. The ground finish and DIN 338 geometry ensure consistent centre spotting, stable drilling performance and reduced tendency to work-harden the material. Its diameter of 3.90 mm delivers accurate hole sizing suitable for precision assemblies and fixtures.
Suitable for
Drilling holes in stainless steel (INOX) and corrosion-resistant alloys
Precision drilling in toolrooms and repair workshops
Production runs requiring consistent hole diameter and finish
Use in drilling stands, CNC machines and hand-held drills within recommended speed ranges
Key specifications
Material: HSSE (high-speed steel with cobalt)
Diameter: 3.90 mm
Usable (working) length: 43 mm
Overall length: 75 mm
Manufacturing standard: ground to DIN 338 dimensions
Intended application: stainless steel and corrosion-resistant alloys
How to use
Secure the workpiece and ensure correct clamping before drilling. Select appropriate cutting speed and feed for stainless steel to avoid excessive heat and work hardening; lower cutting speeds and steady feed are typically recommended. Use a sharp, correctly mounted drill in the machine or chuck, and apply cutting fluid suitable for stainless materials to improve cooling and chip evacuation. Retract periodically on deep holes to clear chips and maintain hole quality.
Usage recommendations
When drilling stainless steel with the FANAR WIERTLO NWKA HSSE Ø3.90 mm, use moderate spindle speeds, steady feed rates and a quality cutting fluid. Inspect the drill for wear and regrind or replace when edge rounding reduces hole accuracy. For best results in production, match drill size, machine rigidity and coolant strategy to the material and hole depth.
