Milwaukee OPEN-LOK Diamond Grit Blade: 15x Longer Life for Grout Removal

The Milwaukee OPEN-LOK 49-25-2272 diamond grit blade solves the grout removal problem that standard carbide blades can’t touch. 15x longer life than standard carbide grit blades — that’s not marketing fluff. It’s measurable performance contractors need when tackling bathroom remodels and tile repair jobs.

This blade earns its keep through Diamond MAX Diamond Grit: Higher-grade diamonds for superior heat and fracture resistance. At 0.08 lb with a 1/8 inch kerf, it delivers precision grout removal without the constant blade changes that kill productivity on larger jobs.

Diamond MAX Technology and Universal Compatibility

The secret sauce here is Milwaukee’s Unique Bonding Process: Improves diamond retention on the blade surface. Standard carbide blades shed their grit under the heat and friction of grout removal. Milwaukee’s diamond bonding keeps those cutting particles where they belong — on the blade, not in your shop vac.

Reinforced Universal Fit OPEN-LOK Anchor: Provides stronger grip and rapid blade changes. This matters when you’re switching between flush cuts and detail work. The Universal Fit OPEN-LOK anchor for quick-change capability across 100+ non-Starlock oscillating tools means it’ll work with whatever multi-tool’s already in your truck — Milwaukee M12 and M18 Multi-Tools, Major brands of non-Starlock oscillating tools (DeWalt, Makita, etc.).
