## Long description

DeWalt DT90338-QZ is a bi-metal hole saw supplied as a single piece for drilling larger-diameter openings in construction and installation work. The saw features patented tooth forms that optimise chip removal and a high-speed steel cutting edge for effective cutting through wood, metal and plastic. Its deep design and capacity for thicker materials make it suitable for tasks such as electrical, plumbing and HVAC openings where clean, durable holes are required.
Advantages
The hole saw offers up to 2× longer life compared with the prior generation of DEWALT bi-metal hole saws, achieved through improved tooth geometry that reduces clogging and wear. A large continuous slot provides leverage for fast plug ejection and easy removal, while the high-speed steel cutting edge ensures versatile drilling performance across different materials. The deep cut design allows cutting through 2-by dimensional lumber in a single pass and accommodates materials up to 44 mm thick.
Suitable for
Cutting holes for electrical installations (cable entries, junction boxes)
Creating openings for plumbing pipes and fittings
HVAC duct and vent cutouts
Drilling through wood, thin metals and plastics on-site

How to use
Fit the DeWalt DT90338-QZ hole saw to a compatible arbor and secure it to the drill according to the arbor manufacturer’s instructions. Mark the centre point for the hole, start drilling at low speed to establish the cut, then increase speed as appropriate for the material. Use steady, even pressure and allow the saw to clear chips periodically; use the large slot to eject the cut plug when the hole is complete. Follow safe drilling practices, including appropriate personal protective equipment and secure workpieces.
Usage recommendations
For best results, use the saw at recommended speeds for the specific material and ensure the arbor and pilot bit are suitable for the hole diameter. When cutting thicker or hard metals, withdraw periodically to clear chips and avoid overheating. Store dry to prevent corrosion and inspect teeth before use.
