Diamond Drill Coolants - SMART CUT™

When added to cooled water SMART CUT synthetic water soluble coolant or Mineral Oil will improve your overall diamond drilling and diamond machining operation by as much as 30%. Plain water evaporates at 212 F. Often temperature in your drilling zone reaches as much as 500 degrees F. Often water evaporates, before it has a chance of affectively cooling the diamond drill and material being drilled. Resulting in shorter Diamond Drill Life, Material Damage or micro cracks associated with overheating. Water may cool your diamond drill, yet provide poor lubrication properties needed for optimum drilling results.

Using synthetic water soluble coolant or mineral oil with your Diamond Drill will:

  SMART CUT™ Water Soluble Coolant (686kb)

  • Improve Drilling Speed

  • Increase Diamond Drill Life 

  • Improve Material Surface Finish

  • Reduce Chipping

  • Reduce Material Cracking

  • Preserve Material True Micro Structure 

SMART CUT™ Synthetic Water Soluble Coolant is recommended for drilling:

  • Advanced/Technical Ceramics

  • Advanced Materials

  • Glass

  • Quartz

  • Optical Materials

  • Composites

  • Many Types of Natural Stone

  • Precious & Semi-Precious Stone

  • And Many Other Materials

SMART CUT™ Mineral Oil is recommended for drilling:

  • Materials with High Metallic Content

  • Advanced Ceramics

  • Precious & Semi Precious Stones

  • Many Other Ultra Hard Materials


Stream of SMART CUT coolant added to deionized (DI) water reduces material thermal stress, edge damage, and internal cracking, assuring long-term integrity of  material being drilled. Since SMART CUT KOOL is a coolant and lubricant, both the diamond tools and material benefit. 

As a coolant, SMART CUT  KOOL reduces heat caused by friction. As a lubricant, SMART CUT KOOL lowers friction and surface tension, which increases swarf dispersion. 

Contains no nitrides, phosphates, chromates, phenols, heavy metal salts, Petroleum oils, chlorine or phosphorus. Do not add inorganic nitrates, nitrites, or organic-nitro compounds.

SMART CUT™ Mineral Oil is not dilutable. Rated as a food-grade mineral oil that is non-toxic, non-hazardous and non-flammable under normal conditions.  It has no odor, won't burn your skin (unless you are very sensitive) and has a flash point of 275 degrees - way above normal temperatures.

Available in:

  • 1 (one) Quart Bottles

  • 1 (one) Gallon Bottles

  • 5 (five) Gallon Pails

  • 55 Gallon Drums


1 part coolant, & 20 parts water

For use with Diamond Drills

For Example: 1 quart of coolant will give you 5.7 gallons of coolant. When mixed with water.

Why use Coolants?

Coolants increase productivity and the quality of material holes or center core parts. Coolants increase the time interval between tooling changes. This saves the company money by reducing the number of tool or die changes needed. Tooling changes require the shut down of the production lines, therefore less tooling changes will increase productivity. Modern coolants must fulfill two primary functions: cooling and lubrication. Both of these functions are important, but their relative importance depends on the type of operation and material being processed.


Prior to modern high-speed equipment, cooling from a lubricant was not needed. The slow cutting speeds did not generate much heat. The straight lubricants were able to transfer enough heat to avoid damage to the parts and tools. However, modern equipment operates at high speeds. This high speed movement creates tremendous amounts of heat which must be removed by the coolant. Failure to remove the heat and chips in the contact zone, between the cutting tool and the part will shorten tool life and increase the number of tool changes as well as reduce the tolerances of tooling and part because of thermal expansion.


Lubrication provided by the coolant reduces the friction between the tool and material / substrate. The coolant prevents the substrate from sticking to the tool and will increase the surface finish. Some companies are trying to eliminate coolants, which inevitably increase the amount of money spent on tooling and lost production. But some companies feel that this is worth the cost benefit of maintaining the coolant systems and the work associated with the coolants. These companies are in the minority.


1. Operator Sensitivity - SMART CUT KOOL is formulated with operator friendly additives that will not irritate skin (dermatitis), nasal passages, or eyes.

2. Bio-resistance . SMART CUT KOOL is formulated with biocides and fungicides to biologically control the growth of bacteria, fungi, and mold in the coolant system. The bio-resistance will determine its suitability for recycling in large central systems.

3. Corrosion Protection - SMART CUT KOOL is formulated with corrosion inhibitors, which provide protection to machinery and the substrate. The protection needed will be determined by the customers requirements. With proper concentration, no corrosion should occur on the machinery.

4. Hard Water Stability - SMART CUT KOOL should be stable in all water conditions. Hard water ions react with coolant additives and reduce the effectiveness of the coolant solution.

5. Mixability . Concentrate SMART CUT KOOL should mix easily or .bloom. into the water. Any difficulty in mixing will not be tolerated by the customer.

6. Foam - All water based coolants can potentially foam. SMART CUT KOOL is formulated with defoamers to prevent foaming under most conditions. The proper selection of coolant concentration will help alleviate potential problems.

7. Residue - SMART CUT KOOL will not leave a .hard-to-remove. residue on the surface of the machine or substrates. As the water in the coolant. evaporates organic residue will be left on the machines. This residue should not be sticky and should be easily re-dissolved in water.

8. Oxidative Stability - High temperatures and pressures will cause changes in the composition of the coolant, such as fragmentation or polymerization of the additives in the coolant formulation. This can decrease the performance of the coolant and create difficult to remove deposits.

9. Emulsion Stability . Concentrate SMART CUT KOOL mixes easily with water and should not separate or create an invert on the surface of the coolant mixture. Customers currently using soluble oils may be experiencing particular difficulties with this problem.

10. Tramp Oil Rejection - SMART CUT KOOL should reject the tramp oils and way lubricants, which may contaminate the sump. Other coolants which do not reject tramp oils are prone to attack by bacteria and fungal organisms.
