## Summary description

Abraboro INOX RN drill bit, 10.5 mm diameter, made from HSS‑E with 5% cobalt (Co5). Designed for drilling stainless steel (INOX) and other hard metals, featuring a right‑hand (RN) twist and precision ground flute (szlif). Suitable for metalworking, maintenance, and industrial machining tasks requiring higher heat resistance and wear life.

## Long description

Abraboro 10.5 mm INOX RN drill bit made from HSS‑E with 5% cobalt is engineered for reliable drilling of stainless steel and other hard metals. The 10.5 mm diameter and right‑hand twist geometry provide efficient chip formation and stable rotation. Precision ground flutes ensure consistent cutting performance and dimensional accuracy, while the cobalt‑alloyed high‑speed steel delivers higher hot hardness and increased wear resistance compared with standard HSS.
Advantages
The HSS‑E Co5 composition increases red hardness and extends tool life when drilling tough materials. Precision ground flutes and a right‑hand twist create controlled chip evacuation and reduced workpiece snagging. The bit’s geometry and material combination enable sustained performance under elevated cutting temperatures common when machining stainless steel. Suitable for both hand‑held and machine drilling where dimensional accuracy and repeatability are required.
Suitable for
 Drilling stainless steel (INOX) sheets and plates
 Machining of hard steels and alloyed metals
 Maintenance and repair tasks in industrial environments
 Fabrication and metalworking shops requiring repeatable hole quality
Key specifications
 Diameter: 10.5 mm
 Material: high‑speed steel with 5% cobalt (HSS‑E Co5)
 Geometry: right‑hand twist (RN), precision ground flute
 Intended material: stainless steel (INOX) and other hard metals
 Typical applications: through holes, pilot holes, production drilling
How to use
Secure the drill bit in an appropriate chuck ensuring proper centring and clamping. Select cutting speeds and feed rates suitable for HSS‑E when working with stainless steel; use moderate speeds and steady feed to reduce heat buildup. Apply cutting fluid or coolant to improve lubrication and chip removal, and periodically withdraw the bit to clear chips during deep holes. Maintain consistent pressure and avoid excessive dwell to preserve tip geometry and hole accuracy.
Usage recommendations
For best results when drilling INOX, use a dedicated cutting fluid for stainless steel, set lower spindle speeds compared to mild steel, and allow coolant access to the cutting zone. Replace the bit when wear affects hole size or surface finish to maintain consistent hole quality.
