## Summary description

DeWalt DT4943 is a set of cylindrical cobalt drill bits with a diameter of 10.2 mm, supplied as 10 pieces. Made for drilling in hard materials where cobalt alloy bits are required, the set provides durable cutting edges and heat resistance for extended use. Suitable for metalworking, industrial maintenance and repair tasks requiring precision holemaking.

## Long description

DeWalt Cobalt Cylindrical Drill Bit Set DT4943 includes ten 10.2 mm cobalt alloy twist drills designed for drilling in hard metals and demanding work environments. The set is intended for users who need durable cutting edges and improved heat resistance compared with standard high-speed steel bits. Each cylindrical-shank bit fits common industrial chucks and holders for straightforward replacement and consistent concentricity during machining and maintenance operations.
Advantages
The cobalt construction provides increased hardness and wear resistance at elevated temperatures, extending tool life during prolonged or heavy-duty drilling. The precision-ground point and consistent diameter control deliver accurate holemaking and reduced wandering on the workpiece. Cylindrical shanks ensure compatibility with a wide range of drill chucks and collets, allowing stable clamping and repeatable results in metalworking and repair tasks.
Suitable for
Drilling stainless steel and high-alloy steels
Industrial maintenance and repair
Metal fabrication and workshop use
Precision through-holes in hard materials
Key specifications
Material: cobalt alloy (high-speed steel with cobalt)
Diameter: 10.2 mm
Number of pieces: 10
Shank type: cylindrical (round) shank
Point style: precision-ground tip for accurate centring
How to use
Select an appropriate drill speed and cutting fluid suitable for the specific workpiece material. Secure the workpiece to prevent movement, clamp the cylindrical shank firmly in a suitable chuck or collet, and align the drill at the desired location. Apply steady feed pressure and maintain coolant application when drilling stainless or high-alloy steels to control heat and chip evacuation. Retract periodically for deep holes to clear chips and reduce tool temperature.
Usage recommendations
Use cutting fluid when drilling heat-sensitive alloys, start with a pilot hole when working on thick or difficult materials, and replace bits when wear or chipping is evident to maintain hole quality and safety.
