COOLANTS & OILS
Miller's Tooling is proudly a stockist distributor of Excision coolants & cutting oils , also Houghton coolants and cutting oils. Our range includes several types of coolants, slideway oils, machine tool cleaner, rustveto (rust preventative for storage), inhibitor and biocides. Most products ready to go in 20lt drums, although 205lt drums are also available.
IS YOUR COOLANT AT THE CORRECT PERCENTAGE?? The COOLANT MIXER TAP is a great way to mix soluble coolants easily, without touching the coolants. Anyone can simply set the correct ratio of coolant on the coolant mixer valve, turn on the water tap, the venturi mixes coolant to correct ratio all the time. No more guessing!!!
A coolant refractometer is used easily & very handy to check coolant ratio in the machine whenever. As coolant changes so much daily with heat, useage & evaporation. An economy hand held refractometer can even show you when your machine tools coolant has gone off. Will quickly and accurately measure the concentrate to water ratio of metal working coolants, parts cleaners, chromating solutions and many other types of aqueous based solutions and emulsions. With automatic temperature compensation (ATC) & Supplied in hard protective case. Coolant Refractometer Features;
- Scale 0-18 Brix
- Dirty and old coolant is also shown as blurred line. Clean new coolant is shown as a sharp line
We also offer sump soakers (elephant tampons) to drop into the sump to assist soaking up waste tramp oils.
Various types of oil skimmers are also on offer to separate and remove unwanted tramp oils from the machines coolant (see below).
"Rustveto" is the perfect rust preventative to either spray or paint onto finished components for storage.
"Machine Tool Cleaner" is essential when changing coolants or for the annual cleanout. Why bother putting fresh coolant into a contaminated, smelly tank? Machine tool cleaner can be mixed with your old coolant the day before cleanout; continue using the machine, flushing the cleaner thru. The pipes, pump, etc - then dump the lot
24 hours later. Y ou will be surprised how clean the tanks and guards will come up; ready for the new Houghton's coolant to go in the clean tank.

Coolant odour tablets can help keep your machineshop smelling better; simply drop an odour tablet into the coolant tank. Available in tubes of 15 tablets.
Using a refractometer to check your coolant percentage on a regular basis will keep your coolant costs down and keep the coolant performance at its optimum. This will in turn assist better finishes, longer carbide tool life and coolant free of smells and bacteria. Simply put a drop of coolant on the refractometer plate, look through the lens and get an instant coolant % reading; also instant gauging of the coolant's condition.
Tramp oil collecting in the coolant is an expense and can be bacteria creating inside the sump or coolant tank. The tramp oil is generally caused directly from slideway oils being washed off or leaked into the coolant. As the slide oil is not soluble oil like the coolant, it will float on top of the coolant creating a black, scum residue on the surface. This is known as "tramp oil". A lot of CNC machines have this common problem.
Tramp oil covers the coolant like a blanket, in turn, preventing oxygen circulating through the coolant and soon the coolant goes off. Bacteria etc then forms inside the coolant tank, usually not seen; can be irritating and cause dermatitis and the odour is hard to get off your hands and clothes. The stench of rotten eggs as you open the doors of the CNC machine is a pretty good indicator... this is quite a common problem faced by most machineshops.
A quick fix is using "sump soakers" to clear up the tramp oil if not excessive; give the machine a good flush out with Machine Tool Cleaner first. Oil skimmers are available to prevent this problem occurring. Several types of oil skimmers are available at Miller's Tooling.
Disk Skimmers
Miller's Tooling is a Distributor of Mechanical Skimmers that separate oil from Coolant for any style sump.
Coolant is expensive to buy and dispose. It can be destroyed quickly by anaerobic bacteria if tramp oils are not removed. Zebra's GS disk skimmer solves these problems. It automatically separates and removes the tramp oil, extending the coolant's usefulness.

QUAKER HOUGHTON COOLANTS - Only some popular coolants are described here. Please call Miller's Tooling for best advice for what you require in your machine shop. Available in 5lt, 20lt & 205lt drums.
SOLUBLE
CINDOL 305D is a water soluble machining coolant formulated for machining operations on ferrous and non-ferrous metals. The excellent rust preventive properties and biostability of this product ensure trouble free operation while the high lubricity additives improve surface finish. CINDOL 305D mixes well with hard water and emulsions are completely stable. For all machining of non-ferrous metals and is suitable for medium duty cutting on ferrous metals. CINDOL 305D can be used in a variety of machining operations including turning, drilling, tapping and milling. The low foaming characteristics of CINDOL 305D make it an ideal coolant for high pressure “through tool” coolant systems.
SEMI-SYNTHETIC

HOCUT 795 MPB is a semi-synthetic and provides clean running, heavy duty machining performance on both ferrous and non -ferrous metals without the use of chlorinated or sulphurised compounds. It has unique resistance to bacteria and fungal growth that is achieved without the use of traditioinal biocides.
SYNTHETIC
HOUGHTO GRIND 60 is a synthetic chemical grinding fluid formulated to give maximum rust protection, no foam, no petroleum oil and using surface active compounds to keep the wheel clean. It is used by diluting with water, forming a greenish transparent solution.
HOUGHTO-GRIND 260 is a colourless and odourless grinding oil. The low viscosity of Houghto – Grind 260 results in rapid heat removal, longer grinding wheel life, greater flow rates through the filtration system, lower drag out and less residue on machine surfaces and components. It is an ideal multi-application neat grinding oil.
RUST
RUST VETO 4214 utilizes special polar compounds held up in petroleum solvent, such that wet components to be treated for rust protection can simply be immersed, the moisture is displaced leaving a residual rust preventive film following evaporation of solvent.
NEAT OILS
CINDOL 869R was developed specifically as a high perfor-mance lubricant for Aluminium machining and forming.
CUTMAX 226 is a heavy duty straight cutting oil fortified with sulphur, chlorine and extreme pressure additives. This highly compounded oil gives excellent lubricity and efficient anti-weld, as well as high chemical activity, giving excellent machining characteristics at all cutting speeds, and under heavy duty conditions.
CLEANERS
MACHINE TOOL CLEANER is a powerful, effective cleaner for machine tools and central coolant systems. Mix it with water for use. This makes a quick acting solvent-detergent solution that removes grease and gummy deposits from machine surfaces. It also purges caked residue and scum from coolant sumps, lines and fittings. Use it to clean return trenches and main reservoirs in central coolant systems.
