Product Description
CMT 13/16" Plunge Cut Blade for Wood and Nails - Starlock by CMT is a bi-metal oscillating blade engineered for demanding plunge and flush-cut work in wood, wood with embedded nails, porous cement, plasterboard, and plastics. Built on the Starlock arbor system, this 20mm (13/16") blade features an extremely robust, short, and very narrow profile that makes it ideal for cutting tight grooves and working in confined spaces where larger accessories simply cannot reach. Whether you are making a plunge cut through a nail-studded board or trimming flush in a tight corner, this single-piece blade delivers controlled, clean results.
Key Features
- Starlock Arbor Interface (20mm / 13/16"): Locks directly onto Starlock-compatible oscillating multi-tools for maximum power transfer and zero wobble - meaning more energy goes into the cut and less is lost to slippage or vibration.
- Bi-Metal (BIM) Construction: High-speed steel teeth bonded to a flexible spring-steel body - gives the blade the hardness to cut through nails up to 5mm and the flexibility to resist breaking under stress, extending service life in demanding applications.
- 1.4 TS / 18 TPI Tooth Configuration: A tooth geometry designed for fast, aggressive cutting through wood with embedded nails - so you can power through nail-studded lumber, plasterboard, and porous cement without stopping to change blades.
- 1-11/32" Cutting Height: Provides sufficient plunge depth for the majority of plunge and flush-cut tasks in construction, remodeling, and trim work - reducing the need for multiple passes.
- Extremely Robust, Short, and Very Narrow Shape: The compact profile fits into tight grooves and restricted work areas where standard-width blades cannot maneuver - giving you precision control without sacrificing durability.
- Long Life Rating: CMT rates this blade for long service life across wood, nails up to 5mm, porous cement, plasterboard, and plastics - meaning fewer blade changes and lower cost per cut on the job site.
Why This Product
- If you regularly cut through wood that contains embedded nails, switching to a standard wood-only blade means immediate damage or failure. This BIM blade is specifically built to handle nails up to 5mm without sacrificing the blade, keeping your work moving.
- The Starlock arbor interface is engineered for a more secure, form-fitting connection than older universal arbor designs - which translates to less vibration felt through the tool and more consistent cut quality in plasterboard, plastics, and porous cement.
- The short, very narrow blade shape is purpose-built for tight groove cutting and flush work in confined spaces - solving the common problem of blade width getting in the way when working close to walls, floors, or other surfaces.
- Sold as a single piece (1-Pc), this blade is a straightforward replacement or addition for any tradesperson using a Starlock-compatible oscillating multi-tool who needs a reliable BIM option for mixed-material plunge cutting.

Frequently Asked Questions
What arbor system does this blade use?
This blade uses the Starlock (SL) arbor interface, which is a form-fitting connection system. It is compatible with Starlock-compatible oscillating multi-tools from CMT, Metabo, and other manufacturers that accept the Starlock mount.
Can this blade cut through nails, and if so, what size?
Yes. The BIM (bi-metal) construction of this blade allows it to cut through wood with embedded nails up to 5mm in diameter. It is not intended for nails larger than 5mm.
What materials can this oscillating blade cut?
This blade is rated for wood, wood with embedded nails (up to 5mm), porous cement, plasterboard, and plastics. It is not intended for applications outside of these materials.
Why is the blade described as short and very narrow?
The extremely robust, short, and very narrow shape is specifically designed to fit into tight grooves and confined spaces where wider blades cannot operate effectively. This makes it particularly well suited for precision flush-cut and plunge-cut work in restricted areas.
