If you’re looking to fabricate your own exhaust roll bar or even go-kart chassis you need the professional tubing notcher
from Eastwood. It’s a great tool if you’re restoring a car, drag racing, or off-roading. You can make notches in 3/4″ to 3″ OD tubing. It can be mounted directly to your workbench or in a vise and it accepts standard hole saws
. The notcher is adjustable up to 50 degrees by loosening one bolt. The one hand operation is great because it allows you to get the perfect angle and tighten the bolt without another person helping. Many tubing notches require two bolts to be tightened which means you need three hands and maintain the exact angle while adjusting and tightening the bolts.
