Review: Works great, cheaper than the local big box stores Review: For me, this just became the hands down, perfect blade for cutting through cementitious plaster walls. I have a 1939 built house that I am rewiring, and finally got sick of using a sawzall to open up the walls to run wire. A sawzall ended up doing more damage as I cut through one side of each lath, and then started cutting on the opposite side of each lath, and the vibrations ended up ripping out more plaster than I intended. I burned up 3 bimetal blades on my Multi-tool, and didn't even get one opening cut, before deciding to give this Diamond blade a try. For $10 it was worth a try. I have a really high cement and fine aggregate makeup to my plaster walls with no wire reinforcing, and this blade is perfect for my application. Clean, easy cuts through the plaster, then I have to switch out to the wood blades to get through the lath, but it became an infinitely easier job with better results. I cut (6) 12"x12" openings initially (so 24 lf of cement plaster) and I cannot tell any sign of wear. That alone is worth the $10 per blade. ## Features - Designed as a multi purpose blade for grinding applications; commonly used for grout removal - Diamond Grit; a synthetic diamond coating for long life in tough applications - UNIVERSAL FITMENT which allows for use in most oscillating tools ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01GLGFX3K | | ASIN | B01GLGFX3K | | Best Sellers Rank | #59,641 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #28 in Oscillating Tool Blades | | Brand Name | DEWALT | | Color | Silver | | Compatible Material | Ceramic, Stone | | Customer Reviews | 4.2 4.2 out of 5 stars (2,015) | | Customer reviews | 4.2 4.2 out of 5 stars (2,015) | | Date First Available | 21 September 2023 | | Department | Unisex-Adult | | Global Trade Identification Number | 00885911471398 | | Included Components | 1) Diamond Flush Cut Blade | | Is Discontinued By Manufacturer | No | | Item Dimensions L x W | 22.9L x 14.6W centimeters | | Item Type Name | Dewalt - DWA4242 | | Item model number | DWA4242 | | Manufacturer | Dewalt | | Manufacturer | Dewalt | | Material Type | Metal | | Model | DWA4242 | | Part Number | DWA4242 | | Product Dimensions | 1.85 x 14.61 x 9.68 cm; 41 g | | Style Name | Oscillating | | UPC | 885911471398 | | Unit Count | 1 Count | ## Product Details - **Brand:** DEWALT - **Colour:** Silver - **Material:** Metal - **Product dimensions:** 22.9L x 14.6W centimeters - **Style:** Oscillating ## Images ![DEWALT Oscillating Tool Blade, Diamond Grit, Flush Cut (DWA4242) - Image 1](https://m.media-amazon.com/images/I/81GWQzE139L.jpg) ![DEWALT Oscillating Tool Blade, Diamond Grit, Flush Cut (DWA4242) - Image 2](https://m.media-amazon.com/images/I/81JbhtfRRdL.jpg) ![DEWALT Oscillating Tool Blade, Diamond Grit, Flush Cut (DWA4242) - Image 3](https://m.media-amazon.com/images/I/41w5BOg24gS.jpg) ![DEWALT Oscillating Tool Blade, Diamond Grit, Flush Cut (DWA4242) - Image 4](https://m.media-amazon.com/images/I/31NCaHoc3mL.jpg) ## Questions & Answers **Q: Will this cut a house brick?** A: The DWA4242 is designed for grout removal.
