the 3M-patented Greptile™ material, so a secure grip can be held
with less effort or slippage.
Revolutionary patented material

3M™ Greptile™ Gripping Material utilizes an impressive
microreplication technology pioneered by 3M.
Greptile™ Gripping Material has a two-fold effect. First,
it improves grip. Second, it allows a more effortless grip,
which over time, reduces fatigue. Whether in wet or dry
conditions, Greptile™ Gripping Material provides a grip you
can rely on. (Greptile™ available on all models, excluding
the 2" 3M™ Disc Sander 20230.)

3M got the right angle “right” with the new line of
Disc Sanders for metalworking. By adjusting the
head angle from 90º to 97º, a more comfortable
wrist position improves operating ergonomics.
And the easier-handling, lightweight, compact
design generates less vibration, while improving
operator control. 3M™ Greptile™ gripping
technology* provides a secure grip with less effort
and is easy to maneuver. And the adjustable
directional exhaust feature works the way you
want it to.

3M Flap Wheels
™
Flap wheels offer the benefit of a long-lasting supply of fresh
abrasives and load resistance for extended work without abrasive
changeovers and downtime. They also can work flat and contoured
areas equally well.
The 3M line offers mounted and unmounted products containing
3M™ Cubitron™ Abrasive Grain for more aggressive cut and durability,
as well as quality aluminum oxide products. And for final finishing,
nothing beats the consistency of 3M™ Trizact™ Abrasives.

3M Cross and Square Pads
™
Cross pads are used for close-tolerance polishing of small radii
and channels, deburring the ends and insides of tubing, and other
special applications. Square pads are ideal for fast grinding/
blending of channels, fillets, corners or spotting on flat surfaces.
As the square pads rotate, the corners exert a fast, biting action
and gradually wear down, exposing fresh abrasives.
The 3M line offers products containing 3M™ Cubitron™ Abrasive
Grain for more aggressive cut and durability (like the 747D),
as well as quality aluminum oxide products (like the 241D).

Systems for Cutting
You want the right system for cutting tube, pipe and sheet metal,
or for removing gates, risers and more. Fast, smooth and cool
cuts can make the job easier and safer.
3M offers tools and wheels with the power to perform. For fast
cuts, cooler running and longer wheel life, select a wheel containing
3M™ Cubitron™ Abrasive Grain. Cubitron™ Grain, combined with
3M’s 1-horsepower tools, can quickly cut through carbon steel,
stainless steel and other materials.
For reliable performance in general purpose applications,
use 3M™ General Purpose Cut-Off Wheels.
3M Cubitron Abrasive Grain
™
™
This innovative abrasive grain is one
of the hardest, longest-lasting
minerals available. Perfect for
moderate to heavy stock removal,
it’s engineered to cut fast and handle
intense heat and stress applications.
It’s ideal for use with stainless steel.
Compared to others, our product design can help:
• Eliminate process steps
• Improve cut-rate consistency
• Produce finer finishes

Tech Tips
• For greatest cutting efficiency, run the tool at the Max RPM of the
abrasive wheel being used. NOTE: Tool RPM and abrasive RPM mayy
not be the same. Never exceed the Max RPM of the abrasive wheel
being run.
• Never run cut-off wheels on tools without guards.
22
• Reduce cost per part
• Extend disc life
Technical Recommendations
for 3M Air-Powered Tools
™
• Use a clean, dry, lubricated air supply that will give a measured
air pressure at the tool of 6.2 bar (90 psig) when the tool is
running with the lever fully depressed.
• Use an approved 10 mm (3/8") or 13 mm (1/2") x 8 m (25')
maximum length air line.
• Connect the tool to the air supply as shown in Figure 1.
• It is strongly recommended that an air filter, regulator and
lubricator (FRL) be used as shown in Figure 1, to supply clean,
lubricated air at the correct pressure to the tool. If such
equipment is not used, the tool should be manually lubricated.
To manually lubricate the tool:
• Disconnect the air line and put 2 to 3 drops of suitable
pneumatic motor lubricating oil, such as 3M™ Air Tool
Lubricant 20451, into the hose end (inlet) of the tool.
• Reconnect tool to the air supply and run tool for a
few seconds to allow air to circulate the oil.
• Lubricate daily if the tool is used frequently or if
the tool starts to slow or lose power.
• Tools can be run at lower pressures, but should never
be run higher than 6.2 bar (90 psig). If run at a lower
pressure the performance of the tool is reduced.
