Product Description
CMT OMM21-X50 1-1/8" Sharp Corner Scraper for Multi-Material is a 28mm universal arbor scraper blade engineered for precision corner cleaning and surface preparation across a wide range of materials. Designed to fit virtually any oscillating multi-tool with a universal arbor interface, this high-carbon steel blade delivers targeted scraping performance where standard blades cannot reach - tight corners, seams, and joints. The bulk 50-piece pack is ideal for contractors and professionals who need a steady supply of fresh blades on demanding job sites.
Key Features
- Universal Arbor Compatibility - fits most oscillating multi-cutters on the market, so there is no need for adapters or specialized tool holders when switching between machines.
- Sharp Corner Blade Geometry - the square, hard-edged tip gets into tight corners and narrow seams that rounded or segmented blades simply cannot access, delivering cleaner results in less time.
- High-Carbon Steel (HCS) Construction - the hardened steel blade holds a working edge through repeated scraping passes on soft expansion joints, window putty, sealing compound, and insulation materials.
- 2" Cutting Depth - the generous cutting height allows the blade to engage deeper surfaces without repositioning, reducing overall work time on thick coatings or layered materials.
- 50-Piece Bulk Pack - a high-quantity pack means fewer interruptions to reorder, keeping crews productive across extended multi-material scraping projects.
Why This Product
- When a job calls for cutting soft expansion joints, removing window putty or sealing compound, or scraping insulation materials from tight corners, a blade with a true sharp corner profile does the work that curved or tapered scrapers leave unfinished - this blade is purpose-built for exactly those tasks.
- The 50-piece quantity eliminates the compromise between blade freshness and cost efficiency - professionals can swap to a fresh edge at the first sign of reduced performance rather than pushing a dull blade, which means better surface results and less operator fatigue across a full project.
