## Summary description

Cobalt HSS drill bits by DeWalt, 9.5 mm diameter, pack of 10 (model DT4941). Made from high-speed steel with cobalt alloy for improved heat resistance and wear life.

## Long description

DeWalt cobalt HSS drill bits, 9.5 mm diameter, pack of 10 (model DT4941) are high-speed steel bits with added cobalt alloy to increase heat resistance and durability. These straight-shank twist drills are engineered for drilling into hard steels and stainless steel, offering consistent performance in workshop, metal fabrication and maintenance environments. The 9.5 mm size provides a common, versatile hole diameter for fasteners and fittings used in metalworking.
Advantages
The cobalt alloy composition improves red hardness and wear resistance, allowing faster cutting speeds and longer life when working with hardened steels. The high-speed steel core maintains toughness to resist chipping under impact, while the straight shank ensures secure clamping in standard drill chucks. Supplied in a set of 10, the pack reduces downtime with multiple replacement bits available for repetitive tasks.
Suitable for
Drilling holes in mild and hardened steels
Working with stainless steel and heat-resistant alloys
Metal fabrication, repair and maintenance tasks
Workshop and industrial drilling operations
Key specifications
Material: high-speed steel with cobalt alloy
Diameter: 9.5 mm
Shank type: straight shank for standard chucks
Quantity: set of 10 drill bits
Tip type: twist drill point suitable for metal
How to use
Secure the drill bit in the chuck so the shank is held firmly and runout is minimal. Use cutting fluid or lubricant when drilling stainless steel or other heat-prone materials to reduce heat buildup and extend bit life. Start at low speed to establish the hole, then increase RPM appropriate to the material and drill diameter; maintain steady pressure without forcing the bit to avoid breakage. Clear chips regularly to prevent clogging and overheating.
Usage recommendations
For best results on stainless and hardened steels, use a dedicated metal cutting lubricant, operate at moderate spindle speeds, and replace bits that show significant wear or chipping to maintain hole quality and operator safety.
