Product Description
CMT OMF174-X5 3-3/8" Circular Saw Blade for Wood and Metal - BIM Starlock (5-Piece Pack) is a bi-metal oscillating blade engineered for versatility across a wide range of cutting tasks. Designed with a Starlock arbor interface, this 85mm circular-profile blade tackles sheet metal, plastics, fiberglass, CFRP, wood, glazing compound, brass, and bronze with a single tool attachment. The 5-piece pack delivers extended value for professionals and tradespeople who demand long-lasting performance from their oscillating multi-tool blades.
Key Features
- Bi-Metal (BIM) Construction - combines flexibility and hardness in one blade body, allowing it to cut through both wood and metal without swapping tools, reducing downtime on mixed-material jobs.
- Starlock Arbor Interface - provides a secure, tool-free blade mounting system compatible with Starlock-equipped oscillating multi-cutters, ensuring a stable connection that minimizes wobble and improves cut accuracy.
- 85mm (3-3/8") Circular Saw Blade Profile - the circular shape increases cost-effectiveness by distributing wear evenly across the cutting edge, extending overall blade life compared to segmented profiles.
- Designed for Sheet Metal up to 2mm - purpose-rated for thin metal cutting, making it a reliable choice for HVAC work, metalworking trim, and sheet metal fabrication alongside wood and composite materials.
- Compatible with Plastics, Fiberglass, CFRP, Brass, and Bronze - broad material compatibility means one blade handles multiple substrates on the same job site, reducing the number of blade changes needed.
- Long Life Design - built for durability across repeated use on demanding materials, so professionals can count on consistent cutting performance over an extended service period.
- TS 1.27 - TPI 20 Tooth Configuration - a fine tooth pitch optimized for smooth, controlled cuts in thin metals and hard materials, reducing burring and finishing time after the cut.
- 0.028" Teeth Thickness - a precision-ground tooth width that produces narrow kerf cuts, helping conserve material and reduce the force required to push through the workpiece.
- 5-Piece Pack - multiple blades included in a single purchase, providing backup blades ready for immediate use and reducing per-blade cost for high-volume cutting applications.
Why This Product
- For tradespeople working across wood, metal, and composite materials on the same project, this BIM blade eliminates the need to carry multiple blade types - sheet metal up to 2mm, fiberglass, CFRP, plastics, brass, bronze, glazing compound, and wood are all listed compatible materials in one blade.
- The Starlock arbor design ensures a positive-lock connection with Starlock-compatible oscillating tools, giving users confidence that the blade stays firmly seated during plunge cuts and flush cuts in tight spaces.
- The circular profile blade shape is engineered specifically for increased cost-effectiveness, distributing cutting wear more uniformly and reducing the frequency of blade replacement on long or demanding jobs.
- Buying the 5-piece pack means a ready supply of blades on hand - ideal for contractors and professional users who need to keep work moving without waiting for restocking between projects.

Frequently Asked Questions
What arbor type is required to use the OMF174-X5 blade?
The OMF174-X5 uses a Starlock (SL) arbor interface. It is compatible with oscillating multi-cutters that accept the Starlock mounting system, such as those made by CMT and Metabo. Always verify that your tool accepts the Starlock arbor before mounting.
What is the maximum sheet metal thickness this blade can cut?
According to the product data, this blade is rated for sheet metal up to 2mm thick. It is also rated for use on plastics, fiberglass, CFRP, wood, glazing compound, brass, and bronze.
Why is a circular-profile blade more cost-effective than other oscillating blade shapes?
The circular shape distributes wear more evenly around the cutting edge during use, which extends the usable life of the blade. This is noted in the product data as a key design advantage specifically for increasing cost-effectiveness over the blade's service life.
What does BIM mean in the context of this blade?
BIM stands for Bi-Metal, meaning the blade is constructed from two different types of metal bonded together. This construction combines the flexibility of one metal with the hardness of another, allowing the blade to handle both wood and metal cutting tasks without fracturing under the stress of oscillating tool use.
