## Summary description

DeWalt DT4934 is a set of 10 cobalt twist drill bits designed for drilling metal. Each bit has a 6.5 mm diameter and a cylindrical (straight) shank suitable for use in standard drill chucks. Cobalt construction increases hardness and heat resistance for drilling stainless steel, hardened steels and other ferrous metals. Intended for professional and workshop use where durable metal drilling performance is required.

## Long description

DeWalt cobalt twist drill bit set DT4934 consists of ten 6.5 mm diameter straight-shank drills engineered for metalworking. The cobalt alloy composition increases hardness and heat resistance compared with standard HSS bits, making this set suitable for drilling stainless steel, hardened steels and other ferrous metals. Each bit features a cylindrical shank designed for secure clamping in standard drill chucks and workshop drilling machines.
Advantages
The cobalt construction provides improved wear resistance and sustained cutting performance at higher temperatures, reducing premature dulling when working with tough metals. The 6.5 mm diameter is a common size for through-holes, pilot holes and clearance holes in metal fabrication. Straight shanks ensure compatibility with a wide range of handheld and benchtop drills while the consistent tip geometry supports accurate centring and reduced walking on flat metal surfaces.
Suitable for
Drilling stainless steel panels and sheet metal
Creating clearance and through-holes in hardened steel components
Workshop and maintenance tasks requiring repeatable metal holes
Automotive and machinery repair where durable metal drilling is needed
Key specifications
Material: cobalt alloy high-speed steel
Drill diameter: 6.5 mm
Shank type: cylindrical (straight) shank
Point geometry: split/standard tip for centring on metal surfaces
Package quantity: 10 pieces
How to use
Secure the appropriate drill bit in the drill chuck, ensuring the straight shank is tightly clamped and concentric. Mark the drilling position and, if needed, use a centre punch to prevent walking. Select a suitable cutting speed and apply steady pressure; use lower speeds and increased feed when drilling hardened steels. Apply cutting fluid or coolant to reduce heat build-up and extend bit life. Withdraw the bit periodically to clear chips and check hole progress.
Usage recommendations
Use reduced spindle speeds and continuous cutting lubricant when drilling stainless steel or hardened materials. Inspect bits for wear before use and replace any that show significant blunting or chipping to maintain hole quality and operator safety.
