The Gold Standard for Civil Infrastructure
"In the world of 65 HP road sawing, the margin for error is zero. High-torque machines can destroy an average blade in minutes. At Supreme Diamond Tools, we engineered the Supreme Grade Pro Series to be indestructible. By offering an industry-leading 13mm segment and five precision-calibrated bonds, we ensure that elite contractors achieve the fastest cutting speeds in the most challenging aggregate geologies on the planet."
— The Supreme Diamond Engineering Team
The Supreme Grade Pro Concrete Series is our flagship cutting solution, specifically engineered for high-volume flat sawing and highway construction. Designed to handle the massive torque of walk-behind saws up to 65 HP, these blades feature our highest diamond concentration and advanced metallurgical bonds to ensure maximum production efficiency and the lowest cost-per-linear-foot.
Choose the bond that matches your project's local aggregate geology:
| Bond Code | Recommended Aggregate Geology |
|---|---|
| HO1 | Hardest (Flint, Quartz, Chert, Hard River Rock) |
| HO2 | Hard (River Rock, Granite, Slate, Trap Rock, Basalt) |
| HO3 | Medium (Crushed Gravel, Decomposed Granite) |
| HO4 | Soft/Medium (Dolomite, Limestone, Pit Gravel) |
| HO5 | Softest (Soft Shell, Siliceous, Sandstone, Soft Limestone) |
| Product Code | Diameter x Width | Segment Height | Arbor Size |
|---|---|---|---|
| PRO-C14/S | 14" x .155" / .187" | 13mm (.512") | 1" with Pin Hole |
| PRO-C18/S | 18" x .155" / .187" | 13mm (.512") | 1" with Pin Hole |
| PRO-C20/S | 20" x .155" / .187" | 13mm (.512") | 1" with Pin Hole |
| PRO-C24/S | 24" x .187" | 13mm (.512") | 1" with Pin Hole |
| PRO-C36/S | 36" x .187" / .250" | 13mm (.512") | 1" with Pin Hole |
| PRO-C42/S | 42" x .187" | 13mm (.512") | 1" with Pin Hole |
MANDATORY WET CUTTING: High-horsepower saws generate extreme thermal energy. To preserve the integrity of the 13mm segments, ensure constant, high-volume water flow to both sides of the blade. In reinforced concrete, if you feel the blade 'vibrating,' slow your forward travel—this allows the HO series bond to effectively clear the steel rebar fragments without overheating the diamond matrix.

Q: Why is a 13mm segment height necessary for 65 HP saws?
A: High-HP saws apply massive down-pressure. Standard 10mm segments wear too quickly at these production rates. The 13mm height provides the necessary diamond reserve to complete long highway stretches without frequent blade changes.
Q: What happens if I use the wrong bond code?
A: Using a bond that is too hard (HO1) for soft aggregate will cause 'glazing,' where the blade stops cutting. Using a bond that is too soft (HO5) for hard rock will cause the blade to wear out prematurely. Always consult our matrix for the best ROI.

The 20-inch Supreme Grade blade is built for serious contractors. If you’re cutting reinforced concrete or tackling large-scale roadwork, this blade delivers speed, durability, and precision that justify the investment. It’s a blade I trust for demanding jobs where downtime isn’t an option.
As a roadwork and heavy construction contractor, I need blades that can keep up with our 65 HP walk-behind saws—blades that don’t bog down, don’t wear out mid-project, and deliver precise cuts through reinforced concrete and tough aggregates. We’ve used it on three major highway repair projects and a commercial building slab demolition over the past four months, and it’s outperformed every high-power blade we’ve tested.
