CMT OMM11-X50 1-1/8" Plunge and Flush-Cut Blade for Wood and Metal - BIM (50-Piece) is a professional-grade oscillating multi-tool blade engineered for contractors and tradespeople who need reliable performance across a wide range of cutting tasks. Built from bi-metal (BIM) construction, this 1-1/8 in. blade handles wood, plasterboard, plastic, sheet metal, copper pipes, and aluminum profiles with equal confidence. Whether you are making plunge cuts in plasterboard, flush cutting a nail, or trimming copper or aluminum pipe, this blade delivers the versatility needed to keep a job moving efficiently. The 50-piece bulk pack makes it a practical choice for crews that go through blades regularly on demanding worksites.

Key Features

• Bi-Metal (BIM) Construction - combines high-speed steel teeth bonded to a flexible spring-steel body, giving the blade durability in both wood and metal cutting applications without snapping under stress or flex.
• 18 TPI Tooth Configuration - 18 teeth per inch delivers a controlled, smooth cut in sheet metal, copper and aluminum pipe, plasterboard, and wood, reducing the tearout and rough edges that slow finishing work.
• 1-1/8 in. Blade Width with Universal Arbor - the 28mm universal arbor mount is compatible with most oscillating multi-cutters, so you can switch tools or share blades across a crew without needing separate adapters.
• 1-7/8 in. Cutting Depth - sufficient depth for plunge cutting into plasterboard, trimming pipes, and flush cutting protruding fasteners in typical framing and renovation scenarios.
• Plunge and Flush-Cut Geometry - the blade tip is shaped specifically for plunge entry and flush work, so you can start cuts in the middle of a surface and cut level with a floor or wall without damaging adjacent material.
• Multi-Material Capability - rated for wood, plasterboard, plastic, sheet metal, copper, and aluminum profiles, reducing the number of different blades a tradesperson needs to carry to a job.
• 50-Piece Contractor Pack - bulk quantity keeps replacement blades on hand so downtime from a worn or broken blade is minimized on high-volume worksites.

Why This Product

• One blade for wood and metal - the BIM construction and 18 TPI geometry allow a single blade to transition from cutting plasterboard or wood to trimming copper pipe or aluminum profiles without swapping blades mid-task, saving time and reducing tool clutter.
• Designed for real renovation work - the flush-cut capability handles practical site challenges like cutting a nail flush with a subfloor or trimming door casing - tasks that standard blades struggle with due to geometry limitations.
• Universal arbor fit across major tool brands - the 28mm universal arbor design means this blade works with oscillating tools from a wide range of manufacturers, making it a flexible stocking choice for shops and crews using mixed-brand equipment.
• Bulk pack value for high-usage environments - 50 blades per pack supports sustained use in production remodeling, plumbing rough-in, or drywall work where individual blade purchases would become a frequent interruption.
