6. OPERATION
DANGER
DANGER: Do not override the deadman switch on the power unit. Locking
down, obstructing, or in any way defeating the deadman switch on the
power drive unit may result in serious injury.
6.1 SELECT A TOOL BIT
CAUTION
CAUTION: Use of dull or improperly designed Tool Bits or Tool Bits not
manufactured by TRI TOOL Inc. may result in poor performance and may
constitute abuse of this machine and therefore voids the TRI TOOL Inc.
factory warranty.
Select Tool Bit according to the tubing material, the tubing size, and how critical a
near burr free end is.
Use standard entrance angle Tool Bit for carbon steel.
• These Tool Bits also work well with some stainless steel applications if a near
burr free end is not a critical requirement.
Use a high entrance angel Tool Bit for most stainless steels.
• Generally this is the most suitable edge geometry for about 90 % of all of the
stainless steel tubing applications.
Use an extra hook angle Tool Bit for stainless steels which are very soft.
• These stainless steels include materials like 316L, which have been bright
hydrogen annealed, vacuum annealed or annealed and electro-polished.
• Electro-polished stainless steel has a micro-thin surface, which is high in Cr
andNiwhichmakesitverysoft,buttoughanddifculttocutwithoutaburr.
Use a .969” (24.6 mm) tall Tool Bit for 3/16” (4.7 mm) diameter or less tubing.
• The tall Tool Bit may provide some advantages for wall thicknesses less than
.020” (.5 mm).
• ThetallToolBitwillcutveryclosetotheColletface,whichminimizesexing
of the tubing from the cutting pressure.
• The tall Tool Bit will require more time to adjust the tubing position for cutting
and there is some risk of crashing the Tool Bit into the Collet on larger OD
tubing.

12
TRI TOOL INC.
92-0630 Rev. 190612
Use the M-42 Tool Bits with the exotic alloys if high heat resistance is required to
avoid burning the cutting edge of the Tool Bit.
• M-42 can improve the life expectancy of the Tool Bit under some conditions
on stainless steel.
• M-42 Tool Bits are more brittle than the M-2 Tool Bits, therefore there is a
much greater risk of damaging the M-42 Tool Bit when installing the tubing in
the Tube Squaring Machine.
Loss of Tool Bits from damaged edges may not off-set the improved cutting life
that those Tool Bits promise.
Some exotic alloys may require Tool Bits with both the extra hook angle as well
as the M-42 tool steel for heat resistance.
6.2 INSTALL A TOOL BIT
1. Ensure that the Model 301 is disconnected from the power source before
installing a Tool Bit.
2. Insert the Tool Bit into the slot in the Cutting Head. Refer to Fig. 4. This
position is used for .50” (12.7 mm) and smaller diameter tubing. This is the
designed working position of the Tool Bit and will leave virtually no burr with
standard tubing.
• When working with electro-polished stainless steel tubing, use slow cutting
speeds to minimize the ID burr.
• The Tool Bit (P/N 99-1445) may be reversed. Refer to Fig. 4. Use the
reversed position for tubing with an ID greater than .50" (12.7mm).
• With the extreme shear cutting action, the burr on the ID will be virtually
eliminated.
• Minimum burr may be obtained with a slow RPM and a slow feed, which will
cut a continuous chip.
• Terminate the cut with one or two revolutions without feed to square the end
of the tubing.
• The cutting edge of the Tool Bit must be located on the radial centerline.
3. Tighten the Set Screws to secure the Tool bit to the Cutting Head. Refer to
Fig. 5.

6.3 INSTALL A COLLET IN THE MODEL 301
1. Select the proper size Collet for the outside diameter of the tube or pipe to be
squared. The size of the Collet is determined by the outside diameter of the
tube or pipe to be squared.
2. Do not drop the Collet.
3. Always place a hand under the Collet when installing or removing it from the
Model 301.
4. Remove the Knurled Nut from the end of the Model 301.
5. Insert the Collet into the tapered end of the Model 301.
6. Screw the Knurled Nut back onto the Model 301.
7. BesurethatthereisalightlmofgreaseonKnurledNutthreadsatalltimes
to prevent them from galling or freezing during use.
8. Back the Knurled Nut off just enough to allow insertion of the tube or pipe into
the Collet.
9. Partially tighten the Knurled Nut until the tube or pipe may still be moved into
position.
10. Move the tube or pipe approximately 1/16” (1.6 mm) from the Tool Bit.
11. As the Collet closes, the tube is drawn toward the Tool Bit.
12. Do not let the Tool Bit touch the tube or pipe. If it touches it will cause damage
to the Tool Bit or the Tube Squaring Machine when power is applied.
13. Tighten the Knurled Nut to prevent the rotation of the tube or pipe during
machining.

6.4 INSTALL A COLLET IN THE MODEL 301QL
1. Select the proper size Collet for the outside diameter of the tube or pipe to be
squared. The size of the Collet is determined by the outside diameter of the
tube or pipe to be squared.
2. Do not drop the Collet.
3. Remove the Ball Lock Pin from the Collet Clamping Assy of the Model 301QL
by pulling it straight out.
4. Be sure that the Toggle Clamp Lever is in the up position to allow the pin to be
pulled out.
5. Swing the Clamping Head Assy upward to allow the Collet slide into place.
6. Insert the Collet into the tapered Collet Clamping Model 301QL.
7. Swing the Collet Clamping Assy down into position.
8. Insert the Ball Lock Pin completely into the hole provided for it in the Collet
Clamping Assy.
9. Be sure that the Toggle Clamp Lever is in the up position in order to permit
the pin to be pushed into the Collet Clamping Assy.
10. Insert the pipe or tube to be machined into the Collet.
11. Verify a clearance of 1/16” (1.6 mm) between the Tool Bits(s) and the pipe or
tube face as held by the Collet.
12. As the Collet closes, the tube is drawn toward the Tool bit. Do not let the Tool
Bit touch the pipe or tube at this time. To do so will cause damage to the Tool
Bit or the Tube Squaring Machine when power is applied.
13. Lock the tube or pipe in position by pushing the Toggle Clamp Lever all of the
way down.
14. Attach the power supply to the Model 301QL and pull the Trigger to start the
rotation of the Cutting Head.

Model 301 Tube Squaring Machine
92-0630 Rev. 190612
6.6 ADJUST THE CUTTING SPEED
Use the Speed Control to adjust the cutting speed. Refer to section 8, Cutting
Speeds and Feeds, for the recommended cutting speeds.
To obtain a minimum burr tube end, avoid heat build up. When either the tube or
theToolBitgetshot,thetubematerialstartstooworpushawayfromtheTool
Bit edge in the form of a burr. If the cut is done without heat build up, it is a clean
cut with a minimum burr.
Avoid the conditions, which generate excessive heat by:
• Keep the RPM’s low; excessive cutting speed will generate unwanted
heat.
• Keep the chip curling loose; avoid excessive depth of cut.
• Use a sharp Tool Bit.
Rotate the Feed Handle clockwise to bring the Cutting Head and tube closer
together.
The machining operation begins when the Tool Bit contacts the tube or pipe.
If the tube end is not square to the tube axis, the Tool Bit will contact only a small
segment of the pipe during each revolution.
To avoid Tool Bit damage, the feed rate should be very slow until the Tool Bit is
contacting the pipe continually during at least one revolution.
Figure: 8. Model 301 Controls

18
TRI TOOL INC.
92-0630 Rev. 190612
1. Adjust the cutting RPM with the Speed Control to just above the required
cutting speed as the Tool Bit enters the cut.
2. The Tool will slow down slightly as the cutting load increases, apply additional
power to hold the cutting speed.
3. Observe the chip as the machine is cutting.
• The ideal chip will come off in a loose pig tail spiral.
• A chip that is coming off in a tight straight spiral normally indicates that the
feed is too heavy.
• A straight or slightly curled chip normally indicates that the feed is too light.
4. Back off the feed as required to break the chips and let them fall away.
5. Ifasignicantamountofstockmustberemoved,occasionallybackoutofthe
cut and let the Tool Bit spin free in the air to cool.
6. Continue rotating the Feed Handle clockwise until the end of the pipe is
completely machined. Do not to let the Tool Bit cut into the Collet or the Collet
Adapter.
7. Discontinue feed and allow the Cutting Head to rotate one time for stainless
steelanduptothreetimesforothermaterialstoimprovethenishoftheprep
surface. Never let a Tool Bit 'rub’ the surface of a stainless steel tube without
cutting.ThiswillworkhardenthematerialanditwillbedifcultfortheTool
Bittogetunderthematerialinordertonishthecut.Thiswillalsocause
excessive Tool Bit wear.
8. Rotate the Feed Handle counter-clockwise to separate the Cutting Head and
the pipe.
9. Stop the Cutting Head rotation.
10. Release the Trigger.
11. Rotate the Feed Knob counter-clockwise until the Cutting Head clears the
tube or pipe by at least 1/8” (3.2 mm) or more.
12. On the Model 301 loosen the Collet Nut to release the tube or pipe.
13. On the Model 301QL pull the Toggle Clamp Lever back to release the tube or
pipe.
14. If the next cut is to be identical to the previous cut, then follow the sequence
starting with section 6.3, Install a Collet in the Model 301 or section 6.4 Install
a Collet in the Model 301L
15. If the next cut is to be different than the previous cut, disconnect the power
cord and then follow the sequence starting with section 6.1, Select a Tool Bit.
16. End squaring of 1/8” (3.2 mm) diameter or smaller tubing with the Model 301.
