Product Description
CMT OMM11-X5 1-1/8" Plunge and Flush-Cut Blade for Wood and Metal - BIM (5-Piece) is a versatile bi-metal oscillating blade engineered to handle a wide range of cutting tasks across wood, plasterboard, plastic, sheet metal, copper, and aluminium pipes and profiles. With an 18 TPI tooth configuration and a 1 7/8" cutting height, this blade delivers controlled, precise cuts whether you are plunge cutting into plasterboard, flush cutting a nail, or trimming copper pipes and aluminium profiles. The 5-piece pack provides exceptional value for tradespeople and contractors who depend on reliable multi-material cutting performance day in and day out.
Key Features
- Bi-Metal (BIM) Construction - fuses high-speed steel teeth to a flexible spring-steel back, giving the blade the toughness to cut through wood with embedded nails and sheet metal without snapping or wearing out prematurely.
- 18 TPI Tooth Count - strikes a balance between cut speed and surface smoothness, making it equally effective on soft and hard materials including plasterboard, plastics, copper pipes, and aluminium profiles.
- 1 1/8" Blade Width with 1 7/8" Cutting Height - provides enough reach for deep plunge cuts into walls and ceilings while remaining compact enough for flush-cutting work in tight spaces.
- Plunge and Flush-Cut Geometry - purpose-built for starting cuts in the middle of a surface and cutting level with a finished plane, reducing the need for secondary hand-tool cleanup after each pass.
- Universal Arbor (28mm) - compatible with the vast majority of oscillating multi-tools on the market, so the blade fits your existing tool without requiring adapters or special mounts.
- 5-Piece Pack - provides multiple replacement blades in a single purchase, keeping your work moving without interruption when blades wear from heavy multi-material use.
Why This Product
- Designed specifically for both plunge cutting and flush cutting in a single blade format - eliminating the need to swap between specialty blades when tasks shift from cutting into plasterboard to trimming an exposed nail flush with a surface.
- BIM construction allows the blade to move between wood, metal, plastic, and composite materials in the same work session - reducing blade changes and downtime on complex renovation or rough-in jobs.
- The universal 28mm arbor means this blade installs directly on most oscillating multi-tool platforms without adapters, streamlining blade changes on the job site.
- At 5 blades per pack, you have immediate backup blades on hand for extended cuts through abrasive materials like sheet metal and aluminium profiles - materials that consume blades faster than softwood alone.

Frequently Asked Questions
What materials can the CMT OMM11-X5 cut?
This blade is designed to cut wood, plasterboard, plastic, sheet metal, copper pipes, and aluminium pipes and profiles. The BIM construction allows it to transition between these materials without requiring a blade swap.
Is this blade compatible with my oscillating multi-tool?
The OMM11-X5 features a universal 28mm arbor that fits the vast majority of oscillating multi-tool platforms, making it broadly compatible across most major tool brands that accept universal-arbor accessories.
What is the difference between a plunge cut and a flush cut, and can this blade do both?
A plunge cut starts in the middle of a surface - such as cutting an opening in plasterboard - while a flush cut removes material level with a finished surface, such as trimming a nail flush with wood. The OMM11-X5 is engineered specifically for both cut types in a single blade.
How deep can this blade cut?
The CMT OMM11-X5 has a cutting height of 1-7/8", which defines the maximum depth of cut achievable per pass when plunge cutting into supported materials like plasterboard or wood.
