Selecting the best saw blade for your needs requires the consideration of several factors:
1. The type of material to be cut, its value and purpose. The more expensive the material, the thinner the blade you need to use to reduce material loss.
2. The capacity of the saw, its condition, blade RPM and other equipment characteristics. For slabbing, thin blades should only be used on machines that are in good condition and are capable of high RPM's. Thicker blades usually give better service for general slabbing purposes. 3. Production volume to be cut.
4. Operator experience. Generally, thinner blades should only be used by experienced operators as they can be more easily damaged. For school room type conditions, thicker blades will generally last longer.
5. The type of coolant required by both the bade and saw. Some saws and blades should only used with oil, while others can be used with just water or water with a proper additive. 6. Type of blade rim. The diamond edge of the segmented and notched rim blades have an interrupted surface which improves cutting ability and coolant flow. Most larger blades are of this style.
Sintered continuous rim blades mean just that - the edge of the blade has a continuous rim of sintered diamond matrix. Most smaller and thin rimmed blades are either of the sintered continuous or plated rim type.
Guide to Operating Speeds for Blades
The chart below shows the recommended operating range for various sizes of blades. Blade speed should be matched to the blade used and the type of material being cut. In general, harder materials and blades with a thicker rim require slower speeds, while softer materials and blades with thin rims require faster speeds.

MK - 1000 Saber
The Saber blades are ultra-thin, stainless steel that will conserve gem materials and hold waste to a minimum. This makes them an ideal choice for such precious materials as Sapphire, Jade, Ruby and Opal. The ultra-thin rim cuts with little chipping and leaves a remarkably smooth surface requiring less polishing time.
