Overview

The Spyder 600105 Rapid Core Eject Hole Saw in the 4.5-inch size is built to address one of the most common frustrations with traditional hole saws: removing the plug after each cut. The patented Rapid Core Eject mechanism lets you push the core out at the touch of a button, eliminating the need to stop, remove the saw from the drill, and pry out the plug manually. For professionals making dozens of cuts in a day, this feature alone can save a substantial amount of time and effort.

The saw body is constructed from bi-metal steel for durability and heat resistance, and its variable tooth pitch is engineered to deliver fast, clean cuts through a range of material thicknesses including wood, drywall, plastic, and thin metal. With a cutting depth of up to 1-7/8 inches, it handles most standard wall and framing applications. The saw is designed to work with the Spyder Rapid Switch arbor system, which also allows one-click diameter changes between different Spyder hole saw sizes without tools.
