While you probably don’t think about one until you need it, when in use, you likely have a love-hate relationship with the hole saw. Hole saws generally make quick–or at least quicker–work of what would otherwise be a time-consuming task, but on the other hand, hole saws can often be a pain to work with–just think of stuck plugs of cut material. CMT‘s FASTX4 system takes hole saws into the modern era. Now, you can change saws without tools, easily enlarge existing holes, and remove plugs with ease and without tools.
The saws click in place thanks to a patented Fast Lock System. Unlike other hole saw systems, no tools are required.
The pilot drill bit can fit two hole saws, which allows you to easily and accurately enlarge bores.
Plug removal is also easier and accomplished with one click without any tools required.
CMT has three different series of saws. Series 550 is tungsten carbide tipped and a multi-purpose saw. CMT claims 10 times longer life and five times faster cutting. Made for cutting into metal, the Series 551 is bimetal plus 8% cobalt. CMT claims 50% longer life. The Series 552 is a diamond dry saw for hard materials such as tiles.
