Description
xThe Ultimate 'One-Blade' Solution
"In my 20+ years in the diamond tool industry, I’ve seen contractors waste thousands of dollars by using the wrong blade for abrasive materials. We engineered the Supreme Red Combo to be the only blade you need on the truck. By merging a concrete bond with integrated slant segments for undercut protection, we’ve created a tool that survives asphalt while excelling in reinforced concrete."
— The Supreme Diamond Technical Team
The Supreme Red Combo Diamond Blade (GP-RG Series) is a professional-grade multi-purpose tool designed for contractors who move between concrete, masonry, and asphalt throughout the day. This blade eliminates the need for tool changes by utilizing a hybrid bond and advanced core-protection technology.
🚀 Why Professionals Call it the 'Red Combo' Advantage
- Slant-Segment Undercut Protection: Abrasive slurry from asphalt and green concrete can 'undercut' or erode the steel core below the diamond segment. Our specialized slant segments act as a physical shield, protecting the core and preventing premature segment loss.
- Supreme 15mm Total Height: Featuring a 12mm usable diamond segment atop a 3mm reinforced base, this blade provides 50% more wearable life than standard 10mm blades, delivering a significantly lower cost-per-cut.
- True Multi-Material Bond: Engineered with a sophisticated metal matrix that remains sharp in hard concrete and brick, yet durable enough to resist the high friction of abrasive asphalt and stone pavers.
- Safety-First Laser Welding: Each segment is metallurgically fused to the core using high-intensity laser technology, ensuring maximum bond strength for high-speed dry cutting on gas saws.

💡 Pro Field Tip:
Because the Red Combo is a hybrid tool, it performs best when you allow the blade to 'breathe.' If you've been cutting a long stretch of abrasive asphalt, a quick 30-second cut in a hard concrete block will help re-open the diamond matrix, keeping the 15mm segments aggressive for the next cut.

❓ Professional FAQ
Q: Is the 15mm segment height safe?
A: Absolutely. Our 12+3mm design includes a 3mm reinforced base specifically engineered to stabilize the taller 12mm usable diamond section, ensuring the blade remains stable under high-load cutting.
Q: Can I use this on a walk-behind saw?
A: Yes, these are optimized for handheld high-speed saws and walk-behind saws up to 35 HP. The laser-welded bond is designed for both wet and dry job site conditions.
