## Summary description

DeWalt DT4948-QZ drill bits, each 151 mm long, designed for drilling metal. Supplied as a pack of 5 pieces, these bits are intended for metalworking tasks where a longer reach is required. Suitable for use with compatible power drills for creating holes in steel and other ferrous materials in workshop and construction applications.

## Long description

DeWalt DT4948-QZ drill bit set consists of five high-length metalworking bits, each 151 mm long, designed for drilling holes in steel and other ferrous materials. These twist drill bits are manufactured for use with compatible portable or stationary power drills where extended reach is required. The geometry includes a no-walk tip for simplified centering and reduced wandering on the workpiece, recessed cutting wings for cleaner, burr-reduced holes, and a three-sided shank to prevent slipping in the chuck.
Advantages
The extended 151 mm length provides additional reach for drilling through thicker or hard-to-access workpieces while maintaining stability. The no-walk tip improves initial penetration and reduces the need for manual center punching on most surfaces starting from 5 mm diameter. Recessed cutting wings help produce more accurate, burr-free holes, reducing post-drilling finishing. The three-sided, spin-proof shank secures the bit in standard chucks and reduces slippage under load.
Suitable for
 Drilling through high-alloy steels and ferrous metals with tensile strength up to 1100 N/mm²
 Workshop and industrial metal fabrication where longer drill reach is required
 On-site construction drilling with portable drills into structural metals
 Applications requiring clean, precise holes with minimal deburring
Key specifications
 Length: 151 mm per bit
 Material application: steels and ferrous metals
 Suitable tensile strength: up to 1100 N/mm²
 Tip type: no-walk centering tip for easier penetration
 Cutting geometry: recessed cutting wings for reduced burrs
 Shank design: three-sided, spin-proof shank for improved grip
 Pack quantity: 5 pieces
How to use
Select a drill speed appropriate for the metal type and diameter, secure the DeWalt bit firmly in a compatible chuck, and position the no-walk tip at the intended drilling point. Apply steady pressure without forcing the bit; allow the tool to cut at its designed feed rate. Use cutting fluid or lubricant for harder steels to extend bit life and improve hole quality. Retract periodically on deep holes to clear chips and prevent clogging.
Usage recommendations
For best results when drilling high-alloy or hardened steels, use a suitable cutting lubricant, clamp the workpiece securely, and start at a low speed to establish the hole before increasing RPM. Inspect bits for wear and replace when tip geometry or cutting edges are degraded to maintain hole accuracy and reduce risk of breakage.
