Product Description
CMT 1-3/4" Plunge Cut Blade for Wood and Metal - BIM Starlock (1-Piece) is a bi-metal oscillating blade engineered for fast, accurate plunge cutting through a wide range of materials including sheet metal, wood products, plasterboard, soft plastics, and non-ferrous pipe and profiles such as copper, aluminium, and brass. Designed with a Starlock arbor interface and a narrow-waist blade profile, this CMT cutting accessory delivers outstanding cutting speed and efficient swarf evacuation in demanding multi-material applications.
Key Features
- Starlock Arbor Compatibility - fits Starlock-interface oscillating multi-tools for a secure, tool-free blade connection that eliminates slippage and maximizes power transfer during cuts.
- Bi-Metal (BIM) Construction - combines flexibility with tooth hardness, allowing the blade to handle both wood products and metals without snapping or dulling prematurely, extending service life across mixed-material jobs.
- 44mm (1-3/4") Blade Width - sized for controlled plunge cuts in tight and open areas alike, giving the operator precise entry points without overshooting the cut line.
- 1.4 TS - 18 TPI Tooth Configuration - a tooth geometry tuned for sheet metal up to 2mm as well as wood, plasterboard, and soft plastics, reducing blade changes when switching between materials on the same job.
- 2-11/64" Cutting Height - provides meaningful cutting depth for material thicknesses commonly encountered in renovation and trim work, reducing the need for multiple passes.
- Narrow Waist Blade Geometry - promotes outstanding cutting speed and good swarf evacuation, keeping the cut zone clear and reducing heat buildup during extended use.
- Wide Material Range - rated for sheet metal up to 2mm, wood products, plasterboard, soft plastics, and non-ferrous pipe and profiles including copper, aluminium, and brass, making it a versatile single blade for multi-trade tasks.
Why This Product
- Contractors working across multiple materials - wood framing, copper pipe, aluminium profiles, and plasterboard - can rely on a single blade rather than carrying a separate blade for each substrate, reducing tool bag clutter and downtime.
- The Starlock arbor design is compatible with Starlock-interface oscillating tools from CMT, Metabo, and other Starlock-platform brands, making this blade a practical fit for crews already invested in the Starlock ecosystem.
- The narrow waist geometry actively evacuates swarf from the cut, which keeps visibility high and reduces the friction-related heat that shortens blade life - a direct performance benefit on longer or repeated cuts.
- Sold as a single piece (1x blade), this option is ideal for operators who need to replace one blade or try the CMT BIM Starlock profile before committing to a multi-pack purchase.

Frequently Asked Questions
What arbor system does this blade use?
This blade uses the Starlock (SL) arbor interface. It is compatible with oscillating multi-tools that accept the Starlock arbor, including tools from CMT and Metabo among others.
What materials can this blade cut?
According to the product data, this BIM blade is designed for sheet metal up to 2mm, wood products, plasterboard, soft plastics, and non-ferrous pipe and profiles such as copper, aluminium, and brass.
What is the cutting height (depth) of this blade?
The cutting height is 2-11/64", providing sufficient depth for a broad range of plunge-cut applications in renovation, construction, and trade work.
Why is bi-metal (BIM) construction important for this type of blade?
Bi-metal construction bonds high-speed steel teeth to a flexible spring-steel back. This combination allows the blade to flex under load without breaking while the hardened teeth maintain their edge when cutting through both wood-based materials and metals - reducing the frequency of blade replacements on mixed-material tasks.
