## Summary description

DeWalt DT90309-QZ is a single-piece bi-metal hole saw designed for use with drills. Supplied as 1 piece per pack, it is intended for cutting circular holes in various materials compatible with bi-metal construction. Suitable for professional and DIY use where durable, precise hole cutting is required.

## Long description

DeWalt DT90309-QZ is a bi-metal hole saw designed for use with drills, supplied as a single piece. Its deeper saw design allows cutting through thicker materials in a single pass, accommodating up to 44 mm (suitable for 2-by dimensional lumber). The tool is intended for creating precise circular holes in wood and similar materials where bi-metal construction is appropriate.
Advantages
The increased cutting depth reduces the need for multiple passes when working with thicker boards, improving work efficiency. Bi-metal construction provides enhanced durability and wear resistance, offering up to twice the service life compared with the prior generation of DEWALT bi-metal hole saws.
Suitable for
Cutting circular holes in dimensional lumber (2-by)
Drill-based hole cutting in wood and similar materials
Professional carpentry and DIY projects requiring durable hole saws
Key specifications
Maximum cutting depth: 44 mm
Material: bi-metal
Compatibility: suitable for cutting dimensional lumber (2-by)
Durability: up to 2x longer life vs prior DEWALT bi-metal hole saws
Pack quantity: 1 pc (DT90309-QZ, EAN 5054905250539)
How to use
Mark the center point for the hole and securely clamp the workpiece. Mount the bi-metal hole saw on a compatible arbor and install the correct pilot bit. Operate a drill at moderate speed, apply steady pressure and allow the saw to cut without forcing. For thick materials, keep the saw aligned, clear chips periodically and pause to avoid overheating when necessary.
Usage recommendations
Use appropriate personal protective equipment, confirm the arbor and pilot bit compatibility and tightness, and allow the blade to cool between extended cuts to maximize tool life.
