## Summary description

Set of 10 DeWalt HSS-E cobalt drill bits, 3.5 mm diameter (model DT4923). Designed for drilling hard metals and alloys; HSS-E (high-speed steel with cobalt) construction increases heat resistance and wear life. Suitable for use with handheld and stationary drills for metalworking, fabrication, and maintenance tasks requiring precise small-diameter holes.

## Long description

Set of 10 DeWalt cobalt HSS-E drill bits, 3.5 mm diameter, designed for precise metal drilling. These high-speed steel bits with cobalt alloy offer improved heat resistance and extended cutting life compared with standard HSS. The set is intended for making small-diameter holes in hard metals and metal alloys and is compatible with both handheld and bench drills used in metalworking, fabrication and maintenance environments.
Advantages
HSS-E cobalt construction provides higher red hardness and wear resistance, allowing sustained cutting performance at elevated temperatures. The 3.5 mm diameter offers consistent hole size for precision tasks. The set of 10 ensures multiple replacements or simultaneous use on several machines. Ground flutes and a precise point geometry improve chip evacuation and reduce walking, contributing to cleaner holes and longer tool life.
Suitable for
 Drilling small-diameter holes in stainless steel and other hard alloys
 Metal fabrication and assembly work
 Maintenance and repair tasks requiring precise, repeatable holes
 Use with handheld electric drills and drill presses
Key specifications
 Material: high-speed steel with cobalt alloy (HSS-E)
 Diameter: 3.5 mm
 Quantity: 10 pieces per set
 Point geometry: precision-ground for reduced walking and improved centring
 Flute type: ground flutes for efficient chip evacuation
 Intended application: drilling in hard metals and metal alloys
How to use
Secure the workpiece and select the correct drill chuck for a 3.5 mm bit. Use an appropriate clamping method or centre punch to prevent walking when starting the hole. For best results, apply cutting fluid or coolant and start at a moderate speed suitable for the metal being drilled. Use steady pressure and allow the drill bit to remove chips; withdraw periodically to clear chips and maintain cooling. After drilling, deburr the hole if necessary and inspect for correct diameter and finish.
Usage recommendations
For prolonged tool life when drilling stainless steel and hard alloys, use a low-to-moderate spindle speed with continuous cutting fluid and avoid excessive side load. Replace bits from the set when wear or chipping affects hole quality.
