## Summary description

FANAR WIERTLO NWKA drill bit, ø5.20 mm with overall/work lengths 86/52 mm, made from HSSE with TiN coating. Conforms to DIN 338 geometry for twist drills and is intended for drilling stainless steel and similar alloys. Suitable for handheld and machine drilling where wear resistance and precision hole diameter are required.

## Long description

FANAR WIERTLO NWKA ø5.20 mm is a solid twist drill designed to the DIN 338 geometry with a nominal diameter of 5.20 mm and overall/working lengths of 86/52 mm. Manufactured from high-speed steel with cobalt (HSSE) and finished with a titanium nitride (TiN) coating, this drill bit is engineered for drilling stainless steel and similar corrosion-resistant alloys. It is suitable for both portable handheld drilling and machine-mounted operations where precise hole diameter and enhanced wear resistance are required.
Advantages
The HSSE substrate delivers increased heat resistance and toughness compared with standard high-speed steel, while the TiN coating reduces friction and extends tool life under demanding conditions. DIN 338 geometry provides stable cutting behavior, controlled chip formation and reliable centering. The combination of material, coating and standard geometry ensures consistent hole quality, reduced frequency of resharpening and improved performance when working with stainless steels.
Suitable for
 Drilling through stainless steel and similar corrosion-resistant alloys
 Production or maintenance operations on handheld drills
 CNC and machine-shop drilling where repeatable hole diameter is required
 Repair or retrofit work on metal assemblies and fixtures
Key specifications
 Diameter: 5.20 mm
 Overall length: 86 mm
 Working (flute) length: 52 mm
 Material: HSSE (high-speed steel with cobalt)
 Coating: TiN (titanium nitride)
 Geometry: DIN 338 twist drill profile
 Intended material: stainless steel and similar alloys
How to use
Select appropriate spindle speed and feed rate for stainless steel to avoid work hardening; use moderate cutting speeds and steady feed. Secure the workpiece and ensure correct centering before drilling. Apply suitable cutting fluid or coolant to reduce temperature and improve chip evacuation. For handheld use, stabilize the tool to maintain perpendicularity; for machine operation, ensure the drill is held in a rigid chuck or collet. Monitor wear and resharpen or replace the drill when the diameter tolerance or surface finish is no longer acceptable.
Usage recommendations
When drilling stainless steel, start with lower speeds and increase feed rather than speed if cutting becomes difficult. Use high-quality cutting fluid targeted at stainless materials, peck drilling for deep holes to clear chips, and avoid excessive dwell at the bottom of the hole to prevent work hardening. Store the drill in a protective case to preserve the TiN coating and prevent edge damage.
