## Summary description

DeWalt DT4901-QZ is a 2-piece set of twist drill bits designed for right-hand rotation. Supplied in a blister pack, these drill bits are intended for standard drilling tasks using a drill or drill driver. The set contains two twist-style bits suitable for general-purpose hole making and mechanical fastening preparations.

## Long description

DeWalt DT4901-QZ is a two-piece set of right-hand rotation twist drill bits supplied in a blister pack for straightforward storage and transport. Designed for use with drills and drill drivers, these general-purpose twist drill bits are suitable for making holes and preparing mechanical fixings in a range of metals. The bits feature an optimised tip and flute geometry for faster penetration and improved chip evacuation, and a cobalt-enriched High Speed Steel composition for extended cutting life.
Advantages
The 5% cobalt content maintains a sharp cutting edge and offers significantly longer life compared with standard HSS-R bits. A no-walk tip improves initial bite and reduces wandering on the workpiece, producing cleaner, more accurate and burr-reduced holes. Size indicators are positioned away from abrasion for easy reading on qualifying diameters, while a three-sided no-slip shank provides improved grip in the drill chuck. A stronger central core increases fracture resistance during freehand use.
Suitable for
Portable and stationary drilling in high-alloy steels and other metals
Drilling heat- and acid-resistant steels, stainless and chrome-nickel steels
Working with cast iron, bronze and welded seams
General metal fabrication and mechanical fastening preparation
Key specifications
Tool type: twist drill bits, right-hand rotation
Set quantity: 2 pieces
Drill bit diameter: 2.5 mm
Total length: 57 mm
Material compatibility: steel, stainless steel, cast iron, bronze and other metals
Shank type: hex shank for secure chuck engagement
Coating/finish: gold-coloured finish
How to use
Select the appropriate bit from the set and secure it in the drill or drill driver chuck, ensuring the hex shank is fully seated to prevent slip. For best results when drilling metals with higher tensile strength, use steady feed pressure and let the bit cut without excessive force. Apply cutting fluid or lubricant when drilling stainless or heat-resistant steels to reduce heat build-up and extend tool life. Start at low speed to establish the no-walk tip and then increase speed according to material recommendations and drill diameter.
Usage recommendations
Use suitable personal protective equipment, clamp workpieces securely, and maintain consistent feed and speed. For prolonged life and optimum hole quality, use cutting fluid on hard or stainless steels and clear chips frequently.
