## Summary description

Straight shank twist drill bit FANAR Wiertło NWKA with 5.70 mm diameter and overall/working lengths 93/57 mm, manufactured to DIN 338. Made from HSSE high-speed steel with cobalt for machining stainless steel (INOX). Suitable for drilling metal, especially corrosion-resistant alloys, in hand-held drills and drill presses for workshop and industrial use.

## Long description

FANAR Wiertło NWKA drill bit with a 5.70 mm cutting diameter and overall/working lengths of 93/57 mm is a straight-shank twist drill made to DIN 338. Manufactured from HSSE (high-speed steel with cobalt), this drill bit is designed for machining stainless steel and other corrosion-resistant alloys. The geometry and material composition provide improved heat resistance and hardness compared with standard HSS, making it suitable for demanding metalworking tasks in both workshop and industrial environments.
Advantages
The HSSE material with added cobalt increases hot hardness and wear resistance, enabling more consistent performance when drilling stainless steel (INOX) and difficult-to-cut alloys. Conformance to DIN 338 ensures uniform dimensions and reliable shank/drill interface for use in hand-held drills and drill presses. The straight shank simplifies clamping in common chucks and the twist-drill geometry supports efficient chip evacuation and stable drilling at moderate speeds.
Suitable for
Drilling stainless steel (INOX) and corrosion-resistant alloys
General metalworking in workshops and industrial settings
Use in hand-held electric drills and bench drill presses
Creating precise through-holes and pilot holes in metal components
Key specifications
Cutting diameter: 5.70 mm
Overall length: 93 mm
Working (flute) length: 57 mm
Material: HSSE (high-speed steel with cobalt)
Manufacturing standard: DIN 338 (straight shank twist drill)
Shank type: straight shank for standard chucks
How to use
Secure the drill bit in the chuck so that the shank is fully gripped and runout is minimized. Select appropriate cutting speed and feed for stainless steel to avoid work hardening: generally use lower speeds and steady feed rates compared with mild steel. Apply cutting fluid or coolant to reduce heat, improve lubrication, and assist chip removal. Start with a pilot or center punch for accurate hole location if needed, and clear chips periodically to maintain cutting efficiency.
Usage recommendations
For best results when drilling stainless steel, use reduced spindle speeds, consistent feed pressure, and adequate coolant. Monitor drill wear and replace the bit when cutting performance or hole quality declines; re-sharpening is possible for HSSE drills but must respect the original point angle and flute geometry.
