Coolant
Coolant types and Selection
When using Vitrified honing stones you must use a petroleum based coolant. Such as Mobil Met 33 or
Upsilon or any equivalent light honing oil. This is required since vitrified honing stones are not compatible
with water based synthetic coolants.
Diamond stones will work with oil or water based synthetic coolants, but work most efficiently with the
water based synthetic coolants. Rottler Manufacturing recommends the use of Rottler 514-4-71C water
based, synthetic coolant for diamond only applications. This coolant works best when mixed to a 5% –
8% solution.
Refractometer
A Refractometer is used to measure the amount of coolant to water ratio. A 5% to 8% ratio will read a 3 –
5 on the Refractometer. It is important not confuse the ratio with the actual Refractometer reading.
Coolant to Water Ration is 1:20 thus 1 gallon of coolant to 20 gallons of water.
Coolant Pump System
The coolant tank on the HP7A will hold a maximum of 80 gallons of the selected coolant. Unless a
Auxiliary tank is purchased, which will increase the capacity to 100 gallons.
Honing of Alusil, Silitec, and Lokasil Materials
These instructions are for honing Alusil and Lokasil materials with Rottler HP7A honing machine and
water base coolant.
