✓ Best for
Milwaukee MX FUEL 9-inch cut-off saw, 9-inch angle grinders (Makita, DeWalt, Milwaukee). Occasional concrete + asphalt + masonry cuts.
✗ Not for
Heavy production work — step up to 14-inch saw + tier-up blade. Hard aggregate where 9" depth limits cut efficiency.
Pros
- Fits 9-inch angle grinders + cordless cut-off saws (7/8" arbor standard)
- Wet-or-dry rated — flexible for jobsite conditions
- Significantly cheaper than 14-inch blades — right economic tier for occasional 9" work
- Designed for battery saws — engineered for the lower-RPM cordless envelope
Cons
- 9" depth limits the cuts you can make — most jobs need 14" reach
- Shorter blade life vs 14" tier-equivalent (smaller blade = less diamond mass)
The Virginia Abrasives 9-inch Ultra Value is the entry tier for 9-inch tool platforms — cordless cut-off saws and 9-inch angle grinders. Same medium-bond, general-purpose engineering as its 14-inch sibling, scaled down to fit smaller tools and shorter cut-depth jobs.
Who this blade is for
Crews running 9-inch angle grinders (Makita GA9050S, DeWalt DWE4579, Milwaukee M18 FUEL 2786-20) or the Milwaukee M18 9-inch cordless cut-off saw. Jobs where 14-inch reach isn’t needed — small concrete repairs, masonry trim cuts, paver work, occasional asphalt cuts where a full cut-off saw is overkill.
For deeper cuts (over 3 inches), you’ve outgrown the 9-inch platform. Step up to a 14-inch handheld cut-off saw — see our Husqvarna K 970 landing, Stihl TS 420 landing, or Milwaukee MX FUEL COS350 landing.
How it performs
On cured concrete at 4,000 PSI cut wet, expect 80-150 linear feet from a 9-inch Ultra Value. That’s shorter than the 14-inch version (150-250 feet) for one reason: less diamond mass on a smaller blade. Same bond, same construction, just smaller physical scale.
On asphalt and softer block, life extends — softer substrates wear segments less aggressively. Dry cutting halves life vs wet (and triggers silica concerns on any concrete work).
Battery saw considerations
The product title calls out “Battery-Operated Saw” specifically because the engineering is optimized for the cordless envelope — lower RPM, more torque-limited cutting profile than gas saws. Match the blade to the tool: cordless wants efficient cuts because battery is the constraint. A glazed blade burns 2x the battery for the same cut.
Saw fit
- 7/8-inch arbor — standard across 9-inch angle grinders (Makita, DeWalt, Milwaukee)
- Verify your specific tool’s arbor before mounting
- Max RPM 6,600 — fits the 9-inch angle grinder envelope (typically 6,000-6,600 max)

Frequently Asked Questions
Does the 9-inch Ultra Value fit my angle grinder? ▼
Yes for 9-inch grinders — Makita 9-inch (GA9050S, GA9070R), DeWalt 9-inch (DWE4579), Milwaukee M18 FUEL 9-inch (2786-20). 7/8-inch arbor is standard across these tools. Confirm your grinder's arbor before mounting.
Will it fit the Milwaukee MX FUEL cordless cut-off saw? ▼
The MX FUEL 14-inch (COS350) takes 14-inch blades — you want the 14-inch Ultra Value for that saw. There IS a Milwaukee M18 9-inch cut-off saw — that one takes 9-inch blades, and this is the right fit.
How is this different from the 14-inch Ultra Value? ▼
Different platform. The 9-inch is engineered for angle grinders and cordless 9-inch cut-off saws — lower-RPM tools with shallower cut depth. The 14-inch is engineered for handheld gas/battery cut-off saws and chop saws. Same bond philosophy (medium, general-purpose), different physical scale and engineering envelope.
What's the max cut depth on a 9-inch blade? ▼
Approximately 3 inches on a 9-inch grinder or cut-off saw — same constraint that applies to all 9" platform tools. For deeper cuts, step up to a 14-inch saw + 14-inch blade. See our [Husqvarna K 970](/blades-for/husqvarna-k970/) or [Stihl TS 420](/blades-for/stihl-ts420/) saw-model landings for the 14" platform options.
How long does this blade last? ▼
Expect 80-150 linear feet wet on cured concrete. Shorter than 14" equivalent because of less diamond mass. On asphalt or block, blade life extends — softer substrates wear segments more slowly. Dry cutting roughly halves life vs wet.
