Review: The right tool, for the right job - 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. Review: Great for cutting LVP rigid core flooring - I recently installed 900sq. ft. Of Nucore performance lvp flooring. I used this oscillating tool blade to make cutouts around door jambs and cabinets. This thing held up incredibly. Diamond grit has barely worn at all, and I’ve made at least 100 ft of cuts. Downsides: plunge cuts were hard to make without the blade chattering a bunch, chrome finish peeled on the part but that doesn’t really affect its performance. ## 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 | | Best Sellers Rank | #30,101 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #59 in Power Oscillating Tool Blades | | Brand | DEWALT | | Brand Name | DEWALT | | Color | Multi | | Compatible Devices | Most oscillating tools | | Compatible Material | Granite, Marble, Stone | | Customer Reviews | 4.2 out of 5 stars 2,093 Reviews | | Global Trade Identification Number | 00885911471398 | | Included Components | 1) Diamond Flush Cut Blade | | Item Dimensions L x W | 5.75"L x 3.81"W | | Item Type Name | Dewalt - DWA4242 | | Manufacturer | DEWALT | | Material | Blend | | Material Type | Blend | | Model | DWA4242 | | Part Number | DWA4242 | | Product Dimensions | 5.75"L x 3.81"W | | Style | Classic | | Style Name | Classic | | UPC | 885911471398 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** DEWALT - **Color:** Multi - **Compatible Devices:** Most oscillating tools - **Global Trade Identification Number:** 00885911471398 - **Material:** Blend - **Product Dimensions:** 5.75"L x 3.81"W - **Style:** Classic - **UPC:** 885911471398 ## Images ![DWA4242 Diamond Flush Cut Oscillating Blade - Image 1](https://m.media-amazon.com/images/I/81GWQzE139L.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Will this cut a house brick?** A: The DWA4242 is designed for grout removal.

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 used this oscillating tool blade to make cutouts around door jambs and cabinets. This thing held up incredibly. Diamond grit has barely worn at all, and I’ve made at least 100 ft of cuts. Downsides: plunge cuts were hard to make without the blade chattering a bunch, chrome finish peeled on the part but that doesn’t really affect its performance. ### ⭐⭐⭐⭐⭐ The first product worth six stars (in my business anyway) *by A***R on January 8, 2021* For my specific purpose (grinding concrete), this blade is one of the best low-cost, high-convenience discoveries of my business. The blade is long enough to reach into/under door jambs (even with door hung). Being diamond instead of carbide, it cuts concrete well and for a good while and is aggressive but doesn't gouge the concrete. I have 3 cordless oscillating tools (Milwaukee's blade change process is insanely frustrating-- stay away from that one! DeWalt is a 3-second dream to change blades so I have two of those and love them). Anyway, this blade is where it's at for cleaning up concrete corners and reaching under things (drywall, door jambs, drains, etc.). This blade worked so sell that I was able to effectively buzz across a door threshold and along a short section of wall as if it were a fine cup wheel. The longer-than-normal length of the blade (compared with HD consumer grade) probably helped with its longer throw during oscillations. ## Frequently Bought Together - DEWALT DWA4242 Diamond Flush Cut Oscillating Blade - DEWALT Dwa4219 Oscillating Carbide Grout Removal Blade --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tw/products/34517339-dwa4242-diamond-flush-cut-oscillating-blade](https://www.desertcart.tw/products/34517339-dwa4242-diamond-flush-cut-oscillating-blade) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-07-05*
