The Raceline Tube Notcher is a quality, precision made, and fully functional hole saw notcher. Constructed from CNC machined billet aluminum with heavy duty 1 inch thick arms, it uses sealed needle bearings to support the 1 inch OD shaft. The shaft uses an easy to replace insert to eliminate the need for full shaft replacement in the case of damaged threads. A thrust bearing at the pivot point decreases the movement and tightens at the desired angle.

With 3 inch OD capacity, the notcher can notch anywhere in a 210 degree arc. Offset notches up to 1 inch are easily performed while the shaft design allows the user to easily return to the zero point for a perfectly centered notch. With reference degree points, the angle can easily be double checked with an angle finder. The notcher can easily be clamped to a tube or pipe for boring holes.
