Product Description
CMT 3-3/8" Radial Saw Blade for Multi-Mat - HCS Starlock by CMT is a high-carbon steel oscillating blade engineered for cutting soft materials with precision and speed. Designed for Starlock-compatible multi-cutters, this segment blade excels at plunge cuts and flush-to-surface cuts, making it an ideal solution for working in tight corners or alongside adjacent surfaces. Whether you are trimming softwood, cutting plastic, or navigating confined spaces, this 85mm radial saw blade delivers the clean, controlled results that oscillating tool users depend on. Sold as a single piece.
Key Features
- Starlock Arbor Interface - mounts directly onto any Starlock-compatible oscillating multi-cutter without adapters, ensuring a secure, wobble-free connection and maximum power transfer from tool to blade.
- 85mm (3-3/8") Radial Saw Blade Format - the radial geometry allows the blade to reach into corners and cut flush to surrounding surfaces, opening up applications that straight segment blades cannot access.
- High-Carbon Steel (HCS) Construction - HCS material is optimized for soft materials including softwood and plastics, providing fast, aggressive cutting without over-engineering the blade for materials that do not require carbide or bi-metal.
- 1.5 TS - 17 TPI Tooth Configuration - the tooth spacing and set are calibrated for soft material removal, helping the blade clear chips efficiently and maintain cutting speed through the full stroke of the oscillating tool.
- 0.031" Kerf Thickness - a thin kerf reduces material waste and minimizes resistance, meaning the tool works less to push through the cut and the operator experiences reduced fatigue during extended use.
- Engineered Exclusively for Soft Materials - by focusing the blade design on soft materials only, CMT optimizes tooth geometry and steel hardness for that specific task, resulting in cleaner cuts and longer blade life within its intended use range.
- Flush-to-Surface Cutting Capability - ideal for working in corners and cutting flush to adjacent surfaces, this blade eliminates the need for additional trimming or sanding in many finishing scenarios.
Why This Product
- The Starlock arbor system locks the blade directly to compatible oscillating tools, so users who already own a Starlock multi-cutter can swap this blade in quickly and get back to work without hunting for adapters or workarounds.
- The radial saw blade shape is purpose-built for corner access and flush cutting - two of the most common challenges in finish carpentry and trim work - making this blade a targeted solution rather than a general-purpose compromise.
- HCS construction keeps the blade matched to its task: soft materials like softwood and plastics are where this blade performs at its designed level, so buyers working in those materials get a blade that is not over-specified or unnecessarily expensive.
- At 0.031" kerf thickness, the blade removes only the material that needs to go, which matters when making precision cuts close to walls, baseboards, or finished surfaces where even a few thousandths of an inch of extra material removal can affect fit.

Frequently Asked Questions
What types of materials can the CMT OMF113-X1 blade cut?
This blade is designed only for soft materials. Per the product specifications, it is intended for use on softwood and plastics. It should not be used on hard materials, metal, tile, or other substrates outside of its rated soft-material category.
What oscillating tools are compatible with this blade?
This blade uses a Starlock arbor interface, which is compatible with oscillating multi-cutters that accept the Starlock attachment system. Compatible platforms include tools from Bosch, CMT, DeWalt, Fein Multitalent, Makita, Metabo, Milwaukee, Ridgid, and Ryobi, among others that use the Starlock system. Note that some tools may require an adapter.
What does the radial saw blade shape allow this blade to do that a standard segment blade cannot?
The 85mm radial saw blade format is specifically engineered for working in corners and cutting flush to the surface. This geometry allows the blade to reach areas that a standard semicircular segment blade may not access, making it especially useful in finish and trim applications where cuts must be made close to walls or adjacent surfaces.
How does the 0.031" kerf thickness affect the cut?
A 0.031" kerf means the blade removes a very thin channel of material with each pass. This thin kerf reduces cutting resistance, helps preserve material integrity around the cut line, and is particularly advantageous when making precision flush cuts where minimizing material removal is important to the finished result.
