Product Description
CMT 1-3/16" BIM Starlock Plunge Cut Blade for Metal - 5-Piece Pack by CMT is engineered for precise plunge and flush-cutting in sheet metal, hard plastics, and non-ferrous materials. Built on the Starlock arbor system, these bi-metal oscillating blades deliver particularly fine, thin, and precise cuts that are easy to control - making them a go-to choice for professionals tackling copper tubing, aluminium profiles, brass fittings, fiberglass (GRP), and similar materials. The 5-piece pack provides lasting value for job sites where blade longevity and consistent performance are essential.
Key Features
- Starlock Arbor System - Provides a secure, positive-locking mount compatible with Starlock oscillating multi-cutters, eliminating slippage and maximizing power transfer during plunge and flush-cut operations.
- Bi-Metal (BIM) Construction - Combines high-speed steel teeth with a flexible spring-steel body, giving these blades the toughness to cut metal, hard plastics, and non-ferrous profiles without premature tooth wear.
- 1-3/16" Blade Width - A compact cutting profile suited for accurate plunge starts and flush cuts in tight or confined workspaces where control is critical.
- 2" Cutting Depth - Accommodates a generous cutting height, allowing the blade to reach through thicker stock or deeper profiles in a single pass without repositioning.
- 1.2 TS / 21 TPI Tooth Configuration - A high tooth-per-inch count engineered for fine, precise cuts in sheet metal up to 2mm, as well as hard plastics and non-ferrous pipe and profiles.
- Medium Waist Blade Geometry - Accelerates cutting speed and promotes efficient swarf evacuation, reducing heat buildup and keeping the cut path clear for consistent results.
- 5-Piece Pack - Provides multiple blades in one purchase, reducing downtime from blade changes and offering cost efficiency across extended metal-cutting projects.
Why This Product
- Designed specifically for sheet metal up to 2mm, copper, aluminium, brass, and fiberglass (GRP) - giving tradespeople a dedicated oscillating blade rather than a general-purpose tool that compromises cut quality in non-ferrous materials.
- The medium waist geometry actively promotes faster cutting and good swarf evacuation, meaning less time clearing chips and more time working - especially important on production-volume tasks or renovation projects with repetitive cuts.
- Starlock compatibility ensures these blades fit Starlock-equipped multi-cutters from CMT, Metabo, and other Starlock-platform tools, making them a versatile addition to a professional tool kit without requiring adapters.
- At 21 TPI with BIM construction, the blade produces particularly fine and precise cuts in hard plastics and non-ferrous pipe profiles - reducing cleanup time and the need for secondary finishing on exposed or visible cuts.

Frequently Asked Questions
What materials can the CMT OMF157-X5 blade cut?
This blade is rated for sheet metal up to 2mm, hard plastics, and non-ferrous pipe and profiles including copper, aluminium, brass, and fiberglass (GRP). It is a fine-cut blade optimized for these specific material types rather than general wood cutting.
What arbor type does this blade use, and which tools is it compatible with?
The OMF157-X5 uses a Starlock (SL) arbor. It is compatible with oscillating multi-cutters equipped with a Starlock interface, including compatible tools from CMT and Metabo, among other Starlock-platform machines.
Why does this blade have a medium waist design?
The medium waist geometry is engineered to achieve faster cutting speeds and improved swarf evacuation. This means metal chips and debris clear away from the cut zone more efficiently, reducing heat and keeping the blade cutting cleanly through non-ferrous materials and hard plastics.
What does the 21 TPI tooth count mean for cut quality?
At 21 teeth per inch (1.2 TS - 21 TPI), this blade is designed to produce particularly fine, thin, and precise cuts. The high tooth count reduces material tear-out and gives the user easy control over the cut path, which is especially valuable when cutting visible or finish-critical surfaces in sheet metal or non-ferrous profiles.
