Drill Bit FANAR WIERTLO NWKA Ø10.60 mm, length 87/133 mm, HSSE, for stainless steel, DIN 338

FANAR WIERTLO NWKA Ø10.60 mm drill bit with a nominal diameter of 10.60 mm and overall/working lengths of 133/87 mm is manufactured to DIN 338 standards from HSSE material. Engineered for drilling stainless steel (INOX) and similar alloys, this solid drill bit combines a standard straight shank profile with a geometry suitable for demanding metalworking tasks on hand-held drills and drill presses. The HSSE composition provides improved hardness and wear resistance compared with conventional high-speed steels, helping to maintain cutting performance during extended use in industrial and workshop settings.

Advantages

This FANAR HSSE NWKA drill bit offers reliable dimensional accuracy and consistent cutting performance when working with stainless steel and other difficult-to-machine materials. The DIN 338 specification ensures a standardized shank and flute geometry for secure clamping and predictable chip evacuation. The HSSE material increases resistance to heat and abrasion, extending tool life under higher cutting temperatures typical of stainless steel machining. Its lengths provide flexibility for through-holes and deeper drilling requirements while remaining compatible with common drill chucks.

Suitable for

• Drilling stainless steel (INOX) and corrosion-resistant alloys
• Metalworking tasks on hand-held electric drills
• Use in drill presses and pillar drills for workshop machining
• Industrial maintenance and fabrication where precise holes are required

Key specifications

• Nominal diameter: 10.60 mm
• Overall length: 133 mm
• Working (flute) length: 87 mm
• Material: HSSE (high speed steel with cobalt)
• Standard: DIN 338 (straight shank twist drill geometry)
• Intended material: stainless steel and similar alloys
• Shank type: straight round shank for standard chucks

How to use

Secure the drill bit in the chuck of a hand-held drill or drill press with appropriate clamping torque to prevent slippage. Use suitable cutting speed and feed for stainless steel—lower cutting speeds and steady feed rates reduce heat build-up and work hardening. Apply cutting lubricant or coolant to improve chip evacuation and reduce friction. Start drilling with a center punch or pilot mark to ensure accurate positioning, and retract periodically for chip clearing when drilling deeper holes.

Usage recommendations

For best results when drilling stainless steel, use moderate spindle speeds and continuous or periodic coolant application. Avoid excessive feed rates that can cause work hardening; allow the tool to clear chips frequently. Inspect the cutting edges for wear and replace the drill when cutting becomes inconsistent to maintain hole quality and operator safety.
