Product Description
CMT OMM09-X1 3/8" Plunge and Flush-Cut Blade by CMT is a narrow, high-performance bi-metal oscillating blade engineered for plunge cutting and flush cutting across a wide range of materials - from wood, chipboard, and plastics to sheet metal, copper, aluminum pipes, and non-ferrous profiles. With a universal arbor fit, this blade is ready to mount on most multi-cutter tools right out of the box, making it a practical choice for trim carpenters, remodelers, plumbers, and general contractors who need one blade to handle demanding cross-material cutting tasks. Sold as a single piece.
Key Features
- Bi-Metal (BIM) Construction - combines the toughness needed for cutting metal with the flexibility required for wood and composite materials, delivering extended blade life across multiple material types without swapping blades.
- 18 TPI Tooth Configuration - 18 teeth per inch produces controlled, fine cuts in sheet metal, aluminum profiles, and copper piping while still performing efficiently in wood and chipboard, reducing tear-out and ragged edges.
- 3/8" Blade Width - the narrow 3/8" profile enables precise plunge cuts in tight or confined areas where wider blades cannot reach, improving accuracy on trim and adjustment work.
- 1-1/8" Cutting Height (Depth) - 1-1/8" of usable cutting depth accommodates typical plasterboard thicknesses, pipe walls, and dimensional lumber trim, giving you the reach needed for most field applications.
- Universal Arbor Interface - fits the vast majority of oscillating multi-cutters on the market, eliminating the need for adapter kits and allowing fast, tool-secure blade changes across different tool brands.
- Flush-Cut Capability - designed specifically for flush cutting nails, trimming non-ferrous profiles, and making precise plunge cuts in plasterboard, so you achieve clean results flush with a surface without damaging adjacent material.
Why This Product
- The BIM construction and 18 TPI geometry allow a single blade to transition between wood, chipboard, plastics, sheet metal, copper, and aluminum profiles - reducing the number of blades you carry on a job site.
- The narrow 3/8" width paired with flush-cut geometry makes this blade the right choice when working on nail flush cuts and adjustment work on non-ferrous profiles where precision matters and clearance is limited.
- Universal arbor compatibility means this blade integrates directly with most oscillating multi-cutters already in use - no adapter hardware required, no additional cost before you can start cutting.
- At 1-1/8" cutting height, the blade handles plunge cuts into plasterboard and sandwich materials in a single controlled pass, making wall and ceiling opening work faster and more consistent.

Frequently Asked Questions
Will this blade fit my oscillating multi-cutter without an adapter?
This blade features a universal arbor interface that is compatible with most oscillating multi-cutters currently on the market. No separate adapter is needed for the majority of tool brands. Check your tool's arbor type before mounting to confirm universal arbor compatibility.
Can this blade cut both wood and metal in the same job?
Yes. The bi-metal (BIM) construction is specifically designed to handle wood, chipboard, and plastics as well as sheet metal, copper pipes and profiles, and aluminum pipes and profiles - making it well suited for mixed-material cutting tasks such as remodel work or plumbing trim-out where you encounter wood framing alongside metal fasteners or pipe.
What is the maximum cutting depth this blade can achieve?
The OMM09-X1 has a cutting height of 1-1/8", which represents the maximum usable cutting depth. This is sufficient for typical plasterboard thickness, thin sheet metal, pipe walls, and standard trim lumber dimensions encountered in most plunge and flush-cut applications.
Is this blade suitable for flush cutting a nail that is proud of a wood surface?
Yes. Flush cutting nails is one of the primary intended uses for this blade. The narrow 3/8" blade width and flush-cut design allow the blade to work close to a surface and sever a nail cleanly without significantly damaging the surrounding wood or substrate material.
