Product Details
Universal Fitment Explained
Most oscillating tools use one of a few common mounting patterns. The DWA4243 includes the required adapters, so it snaps onto your tool without special accessories.
Getting the Most from Your Blade
Use light pressure and let the carbide edge do the work. For grout, score the line twice before plunging deeper. This reduces edge wear and keeps cuts clean.
Frequently Asked Questions
Will this blade fit my Bosch or Fein multi-tool?
Yes, the universal fitment system includes adapters for most oscillating tools, including DEWALT, Bosch, Fein, Milwaukee, and Porter-Cable.
What are the best uses for this blade?
It excels at cutting grout, scraping drywall, removing thin-set, and rough surface prep. The finger shape allows flush cuts into corners.
How long does the carbide edge last?
Carbide grit resists dulling much longer than standard steel, especially on abrasive materials like masonry and cement.
Can I use it to cut wood?
It can cut wood, but it's designed for harder, abrasive materials. For wood, a standard bi-metal blade is more efficient.

Universal fit
I was worried it wouldn't fit my Fein, but it snapped right on. The carbide teeth cut through nails like butter. I've already used it on three jobs. Better than the original blade.

Okay but pricey
It works, but I expected it to last longer. It wore out after a few uses on concrete.

Perfect for trim
I installed new baseboards and this made the job easy. The flush cut design is exactly what I needed.
