## Summary description

DeWalt DT4902-QZ drill bit set consisting of two 3 mm diameter bits designed for drilling with right-hand rotation. Intended for use with compatible drills for creating precise 3 mm holes in suitable materials. Supplied as a 2-piece set for replacement or small projects requiring consistent hole size.

## Long description

DeWalt DT4902-QZ drill bit set includes two 3 mm diameter cobalt-alloy bits engineered for right-hand rotation drilling. Designed primarily for metalworking, these 3 mm drill bits feature a high-speed steel body with 5% cobalt for improved heat resistance and tool life. The bits have a no-walk tip to reduce wandering on curved or smooth surfaces and a reinforced core to enhance fracture stability during freehand drilling. Supplied as a 2-piece set, the bits are suitable for replacement in compact toolkits or for small projects requiring repeated, precise 3 mm holes.
Advantages
The cobalt-alloy composition increases hardness and temperature tolerance compared with standard high-speed steel, enabling more reliable penetration of tougher metals. The no-walk tip improves start accuracy, reducing the need for center-punching in many applications. A non-slip cylindrical shank improves grip in the drill chuck for consistent torque transfer, while the strengthened central core reduces the risk of breakage during heavy or freehand use.
Suitable for
Drilling small-diameter holes in steel and other ferrous metals
Replacement bits for maintenance and repair tasks
Precision metalworking and light fabrication
Compact projects requiring consistent 3 mm hole size
Key specifications
Diameter: 3 mm
Material: High-speed steel with approximately 5% cobalt alloy
Tip: No-walk (reduced walking) tip design
Rotation: Right-hand rotation
Shank type: Cylindrical, non-slip design for secure chuck grip
Overall length: 61 mm
Pack contents: 2 pieces
Primary application: Metal drilling
How to use
Mark the drilling position on the workpiece and, if needed, apply a center punch for very hard or highly polished surfaces. Secure the workpiece and select a suitable drill with a compatible chuck for a cylindrical shank. Start drilling at low speed to establish the hole, then increase speed as appropriate for the material and bit size while applying steady, moderate pressure. Use cutting fluid or coolant when drilling metal to prolong bit life and reduce heat build-up. After use, clean and store the bits in a dry location to prevent corrosion.
Usage recommendations
Use cutting fluid when drilling ferrous metals, avoid excessive side loads to reduce risk of breakage, and ensure the drill chuck is tightened properly to prevent slipping. For repeated or deep holes, periodically withdraw the bit to clear chips and reapply lubricant.
