Product Description
CMT OMF113-X5 3-3/8" Radial Saw Blade for Multi-Mat - HCS - Starlock (5-Piece Pack) by CMT is a high-carbon steel oscillating saw blade designed for cutting soft materials with precision and control. Built around the Starlock arbor system, this 85mm (3-3/8 in.) radial saw blade is engineered to work in tight corners and flush to surfaces - making it a go-to choice for plunge cuts and flush cuts in softwood, plastics, and similar soft materials. The 5-piece pack delivers lasting value for tradespeople and contractors who rely on consistent performance across multiple projects.
Key Features
- Starlock arbor interface - provides a secure, tool-free blade connection compatible with multi-cutters from a wide range of leading power tool brands, reducing downtime and improving blade-change efficiency.
- 85mm (3-3/8 in.) radial saw blade format - engineered specifically for soft materials, allowing controlled, accurate cuts without overreaching into materials the blade is not rated for.
- High-carbon steel (HCS) construction - delivers the combination of flexibility and edge retention needed for cutting wood and plastics cleanly without excessive blade wear.
- 1.5 TS - 17 TPI tooth configuration - optimized for fast, aggressive material removal in soft materials while maintaining a manageable cut quality in each pass.
- 0.031 in. kerf thickness - a narrow cutting width that reduces material waste and keeps cuts precise, especially when working in confined areas or near finished surfaces.
- Ideal for corner work and flush-to-surface cutting - the radial blade geometry lets users reach into tight spaces and cut flush without damaging adjacent surfaces.
- 5-piece quantity per pack - ensures a ready supply of replacement blades on the job, reducing the need for frequent reordering and keeping work moving.
Why This Product
- Purpose-built for soft materials only - rather than a general-purpose blade, this HCS radial saw blade is optimized specifically for softwood and plastics, delivering better-suited performance in those applications compared to blades designed for harder substrates.
- Corner and flush-cut capability - the 3-3/8 in. radial format and Starlock mounting make this blade well-suited for jobs where access is limited and cutting flush to a surface or into a corner is required.
- Broad multi-cutter compatibility via Starlock - the Starlock arbor is accepted by oscillating multi-tools from Bosch, DeWalt, Makita, Milwaukee, Metabo, Ridgid, Ryobi, Fein, CMT, and Festool (with adapter), making this blade a flexible addition to a mixed-brand tool setup.
- Value-oriented 5-pack format - purchasing five blades together at once suits high-volume or repetitive cutting tasks where blade turnover is expected, reducing per-unit cost and keeping the job site stocked.
