Your Eastwood Professional Tubing Notcher is designed with the professional fabricator in mind to 
create precision “fishmouth” notches within a wide range of angles from 90° to 150° in tubing  
up to 3" diameter using a hand drill with a 1/2" or larger chuck. Equipped with roller bearings and  
a 25 mm steel shaft, this notcher should provide years of reliable service.

H.  “T” handle 
I. Hardware 

HELPFUL TIPS:

•  This tool is designed to accurately form an angled “fishmouth” notch in a piece of metal tubing. 

Softer metals such as aluminum and copper tubing can be cut with minimal effort while carbon 

and stainless steel will require greater effort to achieve the same results. Thicker walled tubing 

will also require more effort than thinner walled material.

•  Keep the saw teeth lubricated with cutting oil and keep the feed speed slow. Make sure the 

Arbor Shaft is kept clean of metal chips and dirt and is always well lubricated.  

•  Be aware that finished “fishmouth” cuts have 

extremely sharp

 edges, handle them carefully. 

The rough sawn edges will need to be ground or filed with the final desired shape and properly 

prepared for welding.

•  When finished, clean the tool of metal chips and excess oil. Handle the chips with  

extreme care. 

•  When notching at a high angle the hole saw may bottom on the tubing itself. To finish the notch, 

remove waste material from the hole saw’s path.
