The cut-off saw is delivered with a saw blade 
that is adequate for a variety of cut-off jobs on a 
variety of common materials. A 10-tooth, 
general-purpose blade is provided as standard 
equipment with the machine. 

An optional 8-tooth blade and an optional 
14-tooth blade are available from Wilton. (Refer 
to the Parts section for saw blade part numbers.) 

Refer to Figure 5 for the speeds recommended 
for various materials. These speeds, while 
appropriate for many common shop cutting 
needs, do not encompass the wide variety of 
special blade configurations (tooth pitch and set) 
and special alloys for cutting unusual or exotic 
materials. 

A coarse blade could be used for a solid steel 
bar, but a finer tooth blade would be used on a 
thin-wall steel tube. In general, the blade choice 
is determined by the thickness of the material; 
the thinner the materials; the finer the tooth 
pitch.

A minimum of three teeth should be on the 
workpiece at all times for proper cutting. The 
blade and workpiece can be damaged if the 
teeth are so far apart that they straddle the 
workpiece. 

For very high production on cutting of special 
materials, or to cut hard-to-cut materials such as 
stainless steel, tool steel, or titanium, you can 
ask your industrial distributor for more specific 
blade recommendations. The supplier that 
provides the workpiece material should be able 
to provide you with very specific instructions 
regarding the best blade (and coolant or cutting 
fluid, if needed) for the material or shape 
supplied. 

New blades are very sharp and, therefore, have 
a tooth geometry that is easily damaged if a 
careful break-in procedure is not followed. 
Consult the blade manufacturer’s literature for 
break-in of specific blades on specific materials. 
However, the following procedure will be 
adequate for break-in of Wilton-supplied blades 
on lower alloy ferrous materials. 

1.  Clamp a section of round stock in the vise. 

The stock should be 2 inches or larger in 
diameter. 

2.  Operate the saw at low speed. Start the cut 

with a very light feed rate. 

3.  When the saw has completed 1/3 of the cut, 

increase the feed rate slightly and allow the 
saw to complete the cut. 

4.  Keep the hydraulic cylinder needle valve in 

the same position and begin a second cut 
on the same or similar workpiece. 

5.  When the blade has completed about 1/3 of 

the cut, increase the feed rate.  

Watch the chip formation until cutting is at its 
most efficient rate and allow the saw to 
complete the cut (refer to Evaluating Blade 
Efficiency on page 10). 

The blade is now 

considered ready for use.

The weight of the saw head provides the force 
needed to cut through the workpiece. The cut-off 
saw has a hydraulic cylinder that controls the 
feed rate of the saw. 

The hydraulic feed control circuit consists of a 
single acting hydraulic cylinder (Figure 7) and a 
feed rate control (Figure 5). The feed control 
cylinder resists motion in the downward direction 
to control the feed rate. The control cylinder 
offers no resistance when raised upward. 

The feed rate control knob (Figure 5) controls 
the rate at which the saw head is lowered. The 
control knob (needle valve) controls the rate at 
which the hydraulic fluid is released from the 
hydraulic cylinder. When the needle valve is 
closed, the cylinder is locked. With the needle 
valve slightly open, the cylinder permits slow, or 
light, downward force. Opening the needle valve 
further increases the feed rate and applies more 
weight to the saw blade and workpiece. 

The needle valve is adjusted until the saw is 
operating efficiently. The efficiency of operation 
is usually evaluated by observing chip formation. 
Blade efficiency is further described below.
