Product Description
CMT OMM21-X5 1-1/8" Sharp Corner Scraper for Multi-Material is a 28mm universal arbor oscillating accessory built to tackle precision scraping tasks across a wide range of materials. Designed for use with multi-cutters fitted with a universal arbor, this high-carbon steel (HCS) blade delivers clean, controlled results when cutting soft expansion joints, removing window putty and sealing compound, or trimming insulation materials. This value pack includes 5 blades, making it an efficient choice for professionals and tradespeople who need reliable corner-scraping performance on repeated jobs.
Key Features
- Universal Arbor Compatibility - fits multi-cutters with a universal arbor interface, so the blade works across a broad range of oscillating tools without requiring an adapter.
- 28mm Sharp Corner Blade Profile - the pointed corner geometry reaches into tight angles and confined spaces where standard straight scrapers cannot, delivering precise material removal in corners and edges.
- 2" Cutting Height - provides sufficient depth capacity to scrape through layered materials including sealing compounds, insulation, and expansion joint filler in a single pass.
- High-Carbon Steel (HCS) Construction - HCS material offers the hardness and edge retention needed for scraping soft expansion joints, window putty, and insulation without rapid dulling.
- 5-Piece Pack - multiple blades included in a single package means less downtime swapping accessories and more consistent performance across extended scraping tasks.
Why This Product
- For tradespeople working with soft expansion joints, window putty, or insulation materials, the sharp corner profile and 2" cutting height make this scraper a purpose-built solution - not a general-purpose blade pressed into service for a specialized task.
- The 5-piece value pack is practical for any job site where multiple blades are consumed in a single project, reducing the need for repeat single-blade purchases and keeping work moving without interruption.
