Drill Bit DeWALT DT90247-QZ 1 pc(s)

The DeWALT DT90247-QZ 1 pc drill bit is engineered for durability and precision across a range of general-purpose drilling tasks. Constructed from hardened steel with a ground cutting edge, this single-piece drill bit delivers consistent hole quality and maintains cutting performance under repeated use. It is designed to work effectively in common materials such as wood, soft metals and plastics while meeting the expectations of professional tradespeople and home users who require a reliable, long-lasting drilling accessory.

Advantages

This drill bit offers enhanced wear resistance due to its robust material and finish, reducing the need for frequent replacement. The ground point ensures accurate centring and cleaner hole entry, while the overall geometry provides efficient chip evacuation to prevent clogging during drilling. Its single-piece construction reduces the risk of breakage at connection points, contributing to steady performance in demanding applications.

Suitable for

• Drilling holes in soft and hardwoods for carpentry and joinery
• Creating pilot holes in metal sheets and thin structural metal
• Drilling through plastics and composite panels for fittings and fixtures
• General-purpose repairs, installations and DIY projects

Key specifications

• Material: hardened steel construction for improved durability
• Cutting edge: precision ground tip for accurate centring
• Finish: wear-resistant coating to extend service life
• Design: single-piece drill bit for reduced breakage risk
• Compatible materials: wood, soft metals, plastics

How to use

Select the appropriate drill speed and clamp the workpiece securely before starting. Fit the drill bit into the drill chuck and tighten according to the drill manufacturer’s instructions. Begin drilling at low speed to establish the hole, then increase speed as needed while applying steady, moderate pressure. Withdraw the bit periodically when drilling deeper holes to clear chips and prevent overheating. Allow the bit to cool if it becomes excessively hot during extended use.

Usage recommendations

For best results, use cutting lubricant or coolant when drilling metals to reduce heat and wear. Match drill speed to the material: lower speeds for metals, medium speeds for plastics, and higher speeds for wood. Inspect the bit regularly for signs of wear or damage and replace when cutting performance degrades.
