## Summary description

DeWalt DT4905-QZ is a single twist drill bit designed for right-hand rotation. Supplied as 1 piece, it is intended for drilling applications using compatible drills. The bit’s twist design provides chip removal during rotary drilling and suits general-purpose drilling tasks where a standard right-rotating twist bit is required.

## Long description

DeWalt DT4905-QZ is a single twist drill bit designed for right-hand rotation and general metal drilling. Constructed from high speed steel with a cobalt alloy, the bit combines a strengthened central core with optimised tip and flute geometry to improve penetration, chip evacuation and wear resistance during rotary drilling. Supplied as one piece, this 4.5 mm diameter, 80 mm length twist drill is intended for use where a reliable, high-performance metal-drilling bit is required.
Advantages
The 8% cobalt content maintains a sharper cutting edge and provides significantly longer life compared with standard black oxide bits. The optimised tip and flute geometry doubles penetration speed and improves material removal while reducing heat build-up. A stronger central core increases resistance to breakage, and the no-walk tip helps start holes accurately without slipping on the work surface.
Suitable for
Drilling holes in metal sheets and plates
Fabrication and light-to-medium metalworking tasks
Use with corded or cordless drills that accept standard twist bits

How to use
Install the twist drill bit securely into the drill chuck and tighten according to the drill manufacturer's instructions. Select an appropriate drilling speed for metal work—typically moderate to high speeds for this diameter—apply steady pressure and allow the bit to cut without forcing. Use cutting fluid or coolant for prolonged drilling or thicker material to reduce heat and extend bit life. Clear chips from the hole periodically to maintain efficient cutting and prevent clogging.
Usage recommendations
Use this DeWalt twist drill bit for general metal drilling tasks. For best results, pair with compatible drills and appropriate cutting lubrication, and store the bit in a dry place to protect the cutting edge. Inspect the bit before use and replace it when wear impairs cutting performance.
