"This complete Starrett bo-metalhole saw kit is designed for electricians and contains 20mm, 25mm and 32mm hole saws, packaged in a convenient transport case. Each hole saw has an integrated arbor and pilot drill with an ejector spring, so they are always ready for use whenever you need them. They have 1/4" hex shanks which will slot straight into bit holders or can be gripped in a standard jawed drill chuck. A safety stop at the base of each hole saw means it is imossible to drill beyond the maximum cutting depth.
Optimised for cordless tools, these hole saws are lightweight and require less energy to power them, which means you get longer runtimes out of your batteries.
