OIL/COOLANT
ROC CUT
Roc Cut from Diamond Pacific is a new synthetic water soluble cutting addictive with rust inhibi-
tors. Mix 30 to 1 (water to Roc Cut).
ROC-OIL
Roc-Oil from Diamond Pacific is a oil coolant for heavy duty cutting. Provides excellent blade pro-
tection and will not cause rust to your blade or saw.
STELLAR LUBRICANT
Orange scented mineral oil for use in Lapidary Saws and equipment. This oil is non-toxic, envi-
ronmentally conscious and has excellent heat dispersion properties. Flash Point 305°F.
SMOKEY’S EZ CUT
Synthetic water based cutting agent (mix ratio: 3 ounces per gallon)
WATER
Water is not recommended as a cutting fluid as it is a coolant only and does not promote good
cutting performance. Water can shorten blade life and often frequent blade sharpening may be
required. However, it can be used if a water soluble synthetic agent/additive such as Smokey’s
EZ Cut or Diamond Pacific Roc Cut is used to extend blade life and promote improved sawing.
Even with additives, frequent blade sharpening may be required. These additives have rust inhib-
iting properties but oxidation can still result over time as mist and heat can cover the blade arbor
threaded shaft and jam nut with water during and after sawing. For this reason, if water with or
without an additive is used as a cutting fluid, the user is advised to use water displacing WD-40
sprayed on the blade core and shaft/nut after every cutting session to inhibit rust formation.
Under NO circumstances should any of the following fluids be used in any Lapidary Saw:
AUTOMOTIVE ANTIFREEZE COOLANT
Ethylene glycol based automotive antifreeze and its vapors are hazardous and toxic. Propylene
glycol based antifreeze is non-toxic but has practically no lubricating properties; it functions as a
coolant only and its use will lead to rapid blade wear and dulling.
AUTOMATIC TRANSMISSION FLUID
Does not have adequate lubricating properties for lapidary saws; vapors are considered hazardous
and toxic.
CNC MACHINING FLUIDS
Water soluble synthetic coolants (i.e. Valenite or Cimtool) are often mixed in a 20:1 blend with
water. Fluid vapors are considered hazardous. These fluids do not have adequate lubricating or
rust inhibiting properties for the cast iron and steel parts in lapidary slab and trim saws.
DIESEL, HEATING OIL AND KEROSENE
Very flammable with a low flash points. At least 3 of our commercial cutting customers in Arizona and Pacific
Northwest have burned down their shops using these fluids. Can be very tough to degrease the residue
and aroma out of the cut slabs. These fluids are cheap, but very hazardous to use. Diesel is a benzene
compound which is carcinogenic. All these fluids can cause severe skin rashes and other ailments.
