## Long description

Extreme Bi-Metal Hole Saw 51 mm (DeWalt DT90318-QZ) is a single-piece bi-metal hole saw with a high-speed steel (HSS) cutting edge, designed for cutting clean holes in wood, metal and plastic. Its 51 mm diameter and deep-cut geometry allow one-pass cutting through thicker materials, including 2-by dimensional lumber, while the HSS edge maintains cutting efficiency and durability for repeated use.
Advantages
The bi-metal construction with an HSS cutting edge delivers reliable performance across multiple materials. The deep-cut design supports drilling through up to 44 mm of material in a single pass, and the large continuous slot simplifies plug ejection and removal. Under comparable conditions this model provides up to twice the life versus the prior generation of DEWALT bi-metal hole saws.

Use suitable clamps, personal protective equipment and cutting fluids when drilling metal.
