## Summary description

DeWalt DT4919 is a set of 10 cobalt HSS drill bits with a 2.5 mm diameter. Made for drilling in harder metals, these high-speed steel bits contain cobalt for improved heat resistance and wear life. The set is intended for metalworking, maintenance and industrial applications where small-diameter, durable twist drills are required.

## Long description

DeWalt DT4919 cobalt HSS drill bit set contains ten 2.5 mm twist drills designed for drilling small holes in hard metals. These high-speed steel bits are alloyed with cobalt to increase heat resistance and improve wear life under high-temperature and high-load conditions. The compact set is aimed at metalworking, maintenance and industrial use where precise, durable small-diameter drills are required.
Advantages
The cobalt HSS composition provides increased red hardness compared with standard HSS, enabling longer cutting life and better performance when drilling stainless steel, alloyed steels and other tough materials. The 2.5 mm diameter is ideal for precise pilot holes and mechanical fastening preparation. Supplied as a set of ten, the drills offer immediate replacement options and consistency across repetitive tasks. The twist-drill geometry supports stable chip evacuation and accurate hole centring in metalworking applications.
Suitable for
Drilling stainless steel and alloy steels
Creating pilot holes for screws and bolts in metal
Maintenance and repair work on machinery and equipment
Light industrial and fabrication tasks requiring small-diameter holes
Key specifications
Material: cobalt-alloyed high-speed steel (HSS-Co)
Diameter: 2.5 mm
Set quantity: 10 drill bits
Type: twist drill for metal
Intended use: drilling in harder metals and alloys
How to use
Select an appropriate drill speed and feed rate for 2.5 mm cobalt HSS drills when working with the target material; use lower speeds and steady pressure for stainless and high-alloy steels to reduce heat buildup. Secure the workpiece in a vice or clamp and mark the drilling point. Use a centre punch if high positional accuracy is required. Fit the drill to a compatible drill chuck, ensure runout is minimal, and start at a low speed to establish the hole. Apply cutting fluid suitable for metalworking to improve cooling and chip evacuation; withdraw periodically to clear chips when drilling deeper holes.
Usage recommendations
For best tool life, avoid excessive speeds and overheating; use appropriate cutting fluid and gradual feed. Inspect bits for wear or chipping before reuse and replace damaged drills to maintain hole quality and safety.
