## Summary description

DeWalt DT4938-QZ is a high-speed steel (HSS) drill bit 117 mm long, designed for drilling metal. Supplied as a pack of 10 pieces, it suits workshop and professional applications for creating precise holes in steel and other ferrous and non-ferrous metals. Use with standard drill chucks for general metalworking and maintenance tasks.

## Long description

DeWalt DT4938-QZ is a high-speed steel (HSS) drill bit with an overall length of 117 mm, supplied in a pack of 10. Designed for drilling metal, this bit is suitable for portable and stationary drills and targets materials with high alloy content and tensile strength up to 1100 N/mm². The tip geometry incorporates a 'no-walk' feature for more accurate starts on flat surfaces and recessed cutting wings that reduce burr formation, delivering cleaner, more accurate holes in steel and other ferrous and non-ferrous metals.
Advantages
The HSS material provides heat resistance and wear performance appropriate for general metalworking. The no-walk tip reduces the need for center-punching on surfaces 5 mm and thicker, improving drilling accuracy and reducing slippage. Recessed cutting wings limit burrs and produce a smoother hole finish, which reduces post-drill rework. Supplied as a pack of 10, the set is convenient for workshop stock or repeated tasks.
Suitable for
 Drilling holes in steel and other ferrous metals
 Working with non-ferrous metals such as aluminum and brass
 Portable or bench drilling where precise hole position is required
 Maintenance, fabrication, and general metalworking tasks
Key specifications
 Material: High-speed steel (HSS)
 Overall length: 117 mm
 Intended use: Metal drilling (ferrous and non-ferrous)
 Tip type: No-walk tip for improved positioning
 Hole finish: Recessed cutting wings for reduced burrs
 Pack contents: 10 identical drill bits
 Suitable chuck: Standard drill chucks
 Recommended material tensile strength: Up to 1100 N/mm²
How to use
Secure the drill bit in a suitable standard drill chuck, ensuring it is centered and tightened. Select an appropriate drill speed and apply steady pressure; use lower speeds and adequate cutting lubricant when drilling harder or thicker metals to reduce heat and extend bit life. For thin or smooth surfaces less than 5 mm thick, consider a starter punch to prevent walking despite the no-walk tip. After drilling, clear chips from the hole and inspect for burrs; light deburring may be performed if required.
Usage recommendations
Use appropriate personal protective equipment (safety glasses, gloves) and clamp workpieces securely. For prolonged runs or harder materials, use cutting fluid and pause periodically to prevent overheating. Store the bits dry and protected to avoid corrosion and preserve cutting edges.
