Product Description
CMT 1-3/4 in. Plunge Cut Blade for Wood and Metal - BIM Starlock (50-Piece) is a bi-metal oscillating blade engineered for contractors and tradespeople who need fast, clean plunge and flush cuts across a wide range of job-site materials. Built with a Starlock arbor interface for a secure, tool-free fit on compatible multi-tools, this 44mm blade handles sheet metal, plasterboard, soft plastics, non-ferrous pipe and profiles, and wood products with equal confidence. The 50-piece bulk pack keeps high-volume work moving without interruption.
Key Features
- Bi-Metal (BIM) Construction - combines a high-speed steel cutting edge with a flexible spring-steel body, delivering the hardness needed to cut metal and the resilience to resist blade fatigue during demanding plunge cuts in mixed materials.
- Starlock Arbor Interface - the Starlock mount provides a direct, form-fitting connection to the blade hub, transferring maximum oscillating power from the tool to the workpiece for faster cutting and less wasted motion.
- 1.4 TS - 18 TPI Tooth Configuration - a variable-pitch tooth pattern sized for both wood products and metal, reducing vibration and chatter while maintaining aggressive material removal in sheet metal up to 2mm thick.
- 2-11/64 in. Cutting Height - sufficient reach to cut through plasterboard, non-ferrous profiles such as copper, aluminium, and brass, and wood-based panels in a single controlled pass.
- Narrow Waist Blade Geometry - promotes fast cutting speed and efficient swarf evacuation, keeping the cut zone clear so the blade stays cool and performance stays consistent through the full 50-piece service life.
- Wide Material Compatibility - sheet metal up to 2mm, wood products, plasterboard, soft plastics, copper, aluminium, and brass all fall within the designed application range, reducing the need to swap blades mid-job.
- 50-Piece Contractor Bulk Pack - lowers per-blade cost for high-volume or multi-trade applications, keeping replacement blades on hand without repeat restocking orders.
Why This Product
- One blade for multiple trade applications - the BIM construction and 18 TPI tooth pattern make this blade equally capable in wood framing, plasterboard finishing, and light metalwork, eliminating the need to carry separate blades for each material type on the same job site.
- Built for Starlock-compatible multi-tools - the Starlock arbor design fits a broad range of oscillating multi-tools from CMT, Metabo, and other Starlock-platform brands, making this 50-piece pack a versatile stockroom staple for shops running multiple tool brands.
- Designed for non-ferrous pipe and profile work - copper, aluminium, and brass pipe and profiles are explicitly within this blade's rated application range, making it a practical choice for plumbing and HVAC rough-in cuts where material types vary.
- High-volume pack reduces downtime - 50 blades in a single SKU means fewer reorder events on extended projects, and the consistent BIM construction across every blade in the pack ensures repeatable cut quality from the first blade to the last.

Frequently Asked Questions
What arbor type does this blade use, and which oscillating tools are compatible?
This blade uses the Starlock (SL) arbor interface. It is compatible with any oscillating multi-tool that accepts the Starlock mount, including tools from CMT and Metabo, among other brands that support the Starlock platform.
What is the maximum sheet metal thickness this blade is rated for?
According to the product specifications, this blade is designed for sheet metal up to 2mm thick, as well as non-ferrous pipe and profiles such as copper, aluminium, and brass.
What does the 1.4 TS - 18 TPI tooth specification mean for cutting performance?
The 1.4 TS refers to the tooth set, and 18 TPI indicates 18 teeth per inch. This configuration is engineered to handle both wood products and metal in a single blade, providing a balance of cutting speed and finish quality across the full range of approved materials.
What does the narrow waist blade geometry offer in practical use?
The narrow waist design is specifically noted to deliver outstanding cutting speed and good swarf (chip) evacuation. Keeping the cut zone clear of debris helps maintain consistent blade temperature and cutting performance, which is especially beneficial during extended use across the 50-piece pack.
