Eastwood Economy Tubing Notcher
Part #21749
Carefully read this operation manual prior to using your tubing notcher.
Please keep this manual for your future reference!
Your EASTWOOD TUBING NOTCHER is designed to create
precision “fishmouth” notches within a wide range from angles
from 90° to 150° in tubing up to 2” diameter using a drill press
or hand drill with a 1/2” or larger chuck.
This tool uses metal cutting hole saws with sharp teeth which produce extremely sharp edges on
cut tubing and dangerous metal chips. Wear heavy gloves and eye protection to prevent severe cuts
and avoid eye injury. Keep loose clothing jewelry and hair away form moving parts.
1. It is important to read all instructions before attempting to
use this tool as there is vital information describing what
not to do to avoid serious injury and damage as well as
what to do.
2. The Eastwood Tubing Notcher is supplied with the Arbor
Shaft installed in a reversed position for shipping purposes.
It will need to be removed and re-installed in the correct
position (Fig. A). Pull out the retaining pin, slide the Arbor
Shaft out of the bore and reposition it with the threaded
arbor toward the mounting base and the Arbor Shaft end
with the tri-flat outward.
3. Also, for shipping purposes, the mounting foot is attached
in a reversed position. Remove the vertical through bolt
and mounting foot and reattach it as shown in Fig A.
The mounting foot is designed to facilitate a vertical drill
press mount or a horizontal bench top and hand drill
mount. It is advisable to use a square to be sure the mounting foot is square to the main body in the desired position
then tighten both bolts securely.
4. Note that the threaded end of the Arbor Shaft has 1⁄2”
threads and a 5/8” threaded adapter loosely attached
(Fig. B). This is to accommodate smaller sized hole saws
with 1⁄2” Dia. mounting holes or larger (up to 2”) hole
saws with 5/8” Dia. mounting holes. For smaller hole saw
use, the adapter must be removed from the Arbor Shaft
however if the 5/8” adapter is to be used, be sure that it is
securely tightened. Use the retaining pin to keep the arbor
shaft stationary while tightening.
Only specifically designed threaded metal
saws are to be used with this unit, severe personal injury can
occur with improper saw use!

1. If mounting the unit in a drill press, be sure that the base
is square to the main body, the foot is securely attached
to the drill press table and the shaft is centered under the
chuck (Fig. C). Place the tri-flat section of the shaft in the
chuck making sure the chuck points are in contact with
the shaft flats.
2. Without turning on the drill press, check the down and
up travel of the drill press spindle checking for binding
or friction in the Tubing Notcher as this can cause severe
damage and personal injury. If binding is observed,
re-adjust as necessary.
1. If using a hand drill, be sure the base of the Eastwood
Tubing Notcher is securely mounted to a stable work
surface or clamped tightly in a solidly mounted vice of
substantial size.
1. Determine the angle of the notch or “fishmouth” to be cut
in the tubing, loosen the three lock bolts slightly and adjust
the Tubing Clamp to the desired angle using the gauge
and tighten the three lock bolts securely (Fig, D).
2. Place the tubing into the “V” notch with the curved
portion of the Clamping Hoop and tighten down with the
“T” handle. (Fig E). Note: Always make your “fishmouth” at
the end of a pre-cut section of tubing, never in the middle
of a longer piece keeping the cut line from going beyond
the centerline of the hole saw (Fig. F).
3. The Arbor Carrier is mounted in the Main Body with 2 bolts
and 3 slots (Fig. G). This is to provide adjustment for the
location of the hole saw based on the angle of the Tubing
Clamp. It is important to keep the hole saw cutting edge
as close to the work as possible: For extreme angles and
larger tubing, the Arbor Carrier will need to be adjusted
outward, conversely, for cuts closer to and including 90°
as well as for smaller diameter tubing, adjust the Arbor Carrier inward. This is done to increase accuracy and
decrease vibration.

Lock bolts
4. Before cutting, be sure the Locking Pin is removed (Fig. H)
and the hole saw is securely tightened on the Arbor.
5. If using a drill press, set the speed for 250 to 500 RPM.
For hand drilling, a variable speed drill is best keeping the
speed lower. For less heat buildup, longer saw life and minimal vibration, slower is better however some high strength
steels cut better at slightly higher speeds.
Be sure to use plenty of cutting oil on the metal saw
teeth and feed the saw slowly.
6. You are now ready to begin cutting precision “fishmouths”
however it is strongly recommended that you make
several practice cuts on scrap tubing to become familiar
with the tool.
Retaining pin
• 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 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 proper
weld prep before welding.
• When finished, clean the tool of metal chips and excess oil while handling the chips with extreme
care. Replace the Lock Pin to keep the Arbor Shaft in place and remove hole saw for safety.

• Eastwood also offers a complete line of welders and welding equipment and accessories.
