Product Description
CMT OMM10-X1 7/8" Plunge and Flush-Cut Blade for Wood and Metal - BIM (1-Piece) is a bi-metal oscillating blade engineered for demanding cutting tasks across a wide range of materials. With a universal arbor interface, this 7/8" blade fits most multi-cutters on the market, giving tradespeople and DIYers a single versatile tool for plunge cutting in plasterboard, flush cutting nails, adjustment work on non-ferrous profiles, and cutting through copper and aluminum pipes and profiles. The BIM (bi-metal) construction pairs high-speed steel teeth with a flexible spring-steel body, delivering both edge retention and resistance to blade fatigue in tough wood-and-metal applications.
Key Features
- BIM (Bi-Metal) Construction - bonds high-speed steel teeth to a flexible spring-steel back, giving the blade the toughness to handle wood, chipboard, plastic, sheet metal, copper, and aluminum without premature tooth wear.
- 7/8" Blade Width - provides a narrow, precise kerf for controlled plunge and flush cuts in tight spaces where larger blades cannot reach.
- 18 TPI Tooth Count - delivers a balanced cut rate that is fast enough for softwood, hardwood, and chipboard while remaining fine enough for clean cuts through sheet metal and non-ferrous profiles.
- 1 7/8" Cutting Height - gives the blade sufficient depth capacity to handle plasterboard thickness, pipe walls, and lumber profiles in a single pass.
- Universal Arbor (22 mm) - fits the majority of oscillating multi-tool brands without an adapter, reducing setup time and making the blade interchangeable across a multi-brand tool collection.
- Multi-Material Capability - cuts wood, chipboard, plastic, sheet metal, copper, and aluminum pipes and profiles, eliminating the need to swap blades when moving between substrates on a job.
- Sold as a Single Piece - lets you purchase exactly the quantity you need, whether as a replacement or to extend a set.
Why This Product
- One blade for multiple materials - the BIM design handles wood, chipboard, plastic, sheet metal, copper, and aluminum in a single tool, cutting downtime when your work involves mixed materials on the same job site.
- Broad tool compatibility without adapters - the 22 mm universal arbor interfaces directly with most oscillating multi-cutters, so you spend less time sourcing adapters and more time cutting.
- Engineered for precision access work - at 7/8" wide, this blade excels at flush cutting nails, adjustment work on non-ferrous profiles, and plunge cutting in plasterboard where control and blade geometry matter as much as speed.
- 18 TPI strikes the right balance - fine enough to produce clean edges in metal and plastic, yet aggressive enough to move quickly through wood and chipboard, making it a practical all-around choice rather than a single-application specialist blade.

Frequently Asked Questions
What oscillating multi-tools is this blade compatible with?
This blade uses a 22 mm universal arbor interface that fits most oscillating multi-cutters without requiring a separate adapter. It is designed for broad cross-brand compatibility with standard multi-tool platforms that accept universal arbor accessories.
Can this blade cut both wood and metal in the same session?
Yes. The BIM (bi-metal) construction allows the OMM10-X1 to cut through wood, chipboard, plastic, sheet metal, copper, and aluminum pipes and profiles, making it suitable for jobs where multiple material types are encountered without needing to change blades.
What does "plunge cut" mean in practical terms for this blade?
A plunge cut means the blade can be driven directly into a flat surface - such as a plasterboard wall or a wood panel - without requiring a pre-drilled starter hole. The 7/8" width and 18 TPI geometry of this blade are specifically configured for controlled plunge entry into the workpiece.
What is the maximum cutting depth this blade can reach?
The cutting height of the OMM10-X1 is 1 7/8", which represents the maximum depth the blade can cut in a single pass. This is sufficient for typical plasterboard, pipe walls, non-ferrous profiles, and dimensional lumber applications.
