## Summary description

Solid high-speed steel HSS-E Co5 drill bit by Ghring with 11.5 mm diameter, INOX RN ground finish (model 142-94). Designed for drilling stainless steel and other metals, the cobalt alloy (Co5) increases heat resistance and tool life. Suitable for use in handheld and bench drills for metalworking, maintenance and fabrication tasks.

## Long description

The Ghring 11.5 mm HSS-E Co5 drill bit, INOX RN ground (model 142-94), is a solid high-speed steel cutting tool intended for drilling stainless steel and other metals. Manufactured with a cobalt-enriched HSS-E alloy (Co5), the bit provides improved heat resistance and wear performance compared with standard HSS bits. The INOX RN ground finish and precise geometry deliver consistent hole quality and extend tool life in demanding metalworking tasks.
Advantages
The cobalt content increases red hardness and thermal stability, allowing higher cutting speeds and longer service life when drilling hardened or heat-conductive metals. RN ground flutes and point geometry ensure accurate centering, reduced chatter and smoother chip evacuation. The solid construction offers durability for repeated use in portable and stationary drilling equipment.
Suitable for
 Drilling stainless steels (austenitic and ferritic grades)
 General metal fabrication and maintenance
 Workshop and on-site drilling with hand-held or bench drills
 Repairs and retrofitting involving thin to medium-thick metal plates
Key specifications
 Material: high-speed steel with cobalt alloy (HSS-E Co5)
 Nominal diameter: 11.5 mm
 Tip/finish: INOX RN ground geometry for improved centering and surface finish
 Design: solid one-piece construction for durability
 Typical applications: metal drilling including stainless steel and other ferrous metals
How to use
Select the appropriate drill speed and feed for 11.5 mm diameter in stainless steel or the target material, keeping speeds lower for stainless and harder alloys to avoid overheating. Use cutting fluid or suitable coolant to improve chip evacuation and reduce heat buildup. Secure the workpiece and clamp properly before drilling, then start at low speed to establish the hole and increase speed steadily as the bit advances. Retract periodically on deeper holes to clear chips and allow cooling.
Usage recommendations
For best results when drilling stainless steel, use moderate spindle speeds, consistent light to medium feed rates, and continuous or intermittent coolant. Inspect the cutting edge for wear and replace the bit when performance declines to maintain hole quality and prevent workpiece damage.
