## Summary description

DeWalt DT4290-QZ drill bit, 5 mm diameter and 50 mm length, designed as a high-speed steel twist bit for drilling precise holes.

## Long description

DeWalt DT4290-QZ 5 mm x 50 mm high-speed steel twist bit is a compact drilling accessory designed for creating precise small-diameter holes. The 5 mm cutting diameter and 50 mm overall length make this bit suitable for use with handheld drills and drill presses. As a high-speed steel (HSS) twist bit, it provides a straightforward solution for general-purpose drilling in mild steel, other metals, wood and many plastics under appropriate conditions.
Advantages
This HSS twist bit offers consistent hole accuracy and edge retention for small-diameter drilling tasks. Its hardened and ground flute geometry improves chip removal and reduces clogging during continuous drilling. The compact 50 mm length gives good rigidity for reduced flex and improved hole roundness, while compatibility with standard drill chucks ensures quick installation and stable performance in common power tools.
Suitable for
 Drilling accurate 5 mm holes in mild steel and other metals
 Woodworking tasks requiring small clean holes
 Plastic components and panels where a standard HSS bit is appropriate
 Repair, assembly and light fabrication jobs
Key specifications
 Drill type: high-speed steel (HSS) twist bit
 Cutting diameter: 5 mm
 Overall length: 50 mm
 Shank: round shank for standard chucks
 Flute: two-flute twist geometry for chip evacuation
 Intended use materials: metal, wood, plastics (dependent on material properties)
How to use
Secure the bit in the drill chuck and tighten firmly to avoid slippage. Select an appropriate rotational speed for the material: lower speeds for harder metals, higher speeds for wood and plastics. Use cutting fluid or lubricant when drilling metal to extend bit life and improve cutting performance. Apply steady pressure, allowing the bit to cut without excessive force, and withdraw periodically to clear chips when drilling deep holes.
Usage recommendations
For best results, pre-mark and center-punch holes in metal to ensure accurate starts. Match drill speed and feed to the work material, and keep the bit cool with light lubricant during metal drilling. Replace the bit if signs of wear or chipping appear to maintain hole quality.
