Product Description
CMT OMM12 1-1/4" Bi-Metal Standard Flush-Cut Universal Blade is a professional-grade oscillating multi-tool blade engineered for plunge cutting and flush cutting across a wide range of materials - from wood and plasterboard to sheet metal, copper pipes, and aluminium profiles. Built from bi-metal (BIM) construction with 18 TPI tooth geometry, this blade delivers controlled, clean results in demanding jobsite conditions. Available in a contractor-friendly 50-piece pack, it mounts to virtually any oscillating tool via its universal arbor interface, making it a reliable go-to for renovation, mechanical, and general construction trades.
Key Features
- Universal Arbor Compatibility - fits most oscillating multi-tool machines on the market, eliminating the need for brand-specific adapters and speeding up tool changes on the job.
- Bi-Metal (BIM) Construction - combines high-speed steel teeth with a flexible spring-steel body, giving the blade both cutting durability and the resilience to resist breakage during demanding plunge and flush-cut operations.
- 18 TPI Tooth Count - provides a balanced cut rate suitable for wood, plasterboard, plastics, sheet metal, copper pipes, and aluminium profiles, reducing the need to swap blades between materials.
- 1-1/4" Blade Width with 1-5/8" Cutting Height - sized for standard flush-cut and plunge-cut tasks, allowing precise work in tight spaces such as cutting a proud nail flush to a surface or plunge cutting into plasterboard.
- 50-Piece Bulk Pack - keeps a supply of fresh blades on hand for high-volume work, reducing downtime and cost per cut on longer projects.
- Multi-Material Versatility - handles wood, plasterboard, plastic, sheet metal, copper pipes, and aluminium profiles in a single blade profile, streamlining your tool kit for mixed-material applications.
Why This Product
- The universal arbor design means this blade works with Fein, Festool, Bosch, Makita, Milwaukee, DeWalt, and most other oscillating multi-cutters - one blade stock covers your entire fleet of tools.
- Bi-metal construction lets you cut through wood with embedded nails and then transition to copper pipe or aluminium profiles without reaching for a different blade, cutting material change time on complex renovation jobs.
- At 18 TPI, the tooth pitch is tuned for both speed and finish quality across hard and soft materials, making it practical for plasterboard demo, flush-cutting fasteners, and plunge cuts in a single session.
- Buying 50 blades at once ensures you always have a sharp blade ready - a critical advantage when cutting abrasive or harder materials that wear edges quickly.

Frequently Asked Questions
What materials can the CMT OMM12 blade cut?
This blade is designed for wood, plasterboard, plastic, sheet metal, copper pipes, and aluminium pipes and profiles. Its bi-metal construction and 18 TPI tooth count make it suitable for mixed-material cutting in one session without needing to switch blades.
Will this blade fit my oscillating multi-tool?
The OMM12 uses a universal arbor, which is compatible with most oscillating multi-tool machines including those from Fein, Festool, Bosch, Makita, Milwaukee, and DeWalt, among others. No additional adapter is typically required for tools that accept a universal arbor connection.
What is the maximum cutting height of this blade?
The cutting height is 1-5/8". This dimension represents the effective depth the blade can reach during plunge cutting or flush-cutting operations.
Why buy the 50-piece pack instead of individual blades?
The 50-piece pack is confirmed in the product data and is ideal for contractors and tradespeople who regularly cut through abrasive or harder materials such as sheet metal and aluminium. Having a supply of fresh blades reduces downtime between blade changes and helps maintain consistent cut quality throughout high-volume work.
