Product Description
CMT 3/8" Plunge Cut Blade for Wood and Nails - BIM Starlock (5-Piece) by CMT is a bi-metal oscillating blade engineered for precise plunge and flush-cutting in wood, wood with embedded nails, porous cement, plasterboard, and plastics. The narrow 3/8" profile and Starlock arbor interface make this blade a practical choice for tight groove work and confined spaces where wider blades cannot reach. This 5-piece pack delivers long service life and consistent performance across demanding renovation and finish carpentry tasks.
Key Features
- Starlock Arbor Interface (10mm / 3/8") - locks directly and securely to Starlock-compatible oscillating multi-tools for maximum power transfer and minimal slippage during plunge and flush cuts.
- Bi-Metal (BIM) Construction - combines a flexible spring-steel body with high-speed steel teeth, delivering durability against embedded nails up to 5mm diameter while resisting breakage and extending blade life.
- 1.4 TS - 18 TPI Tooth Configuration - provides an aggressive yet controlled cut through wood, wood with nails, porous cement, plasterboard, and plastics, reducing time spent on material changes.
- 1-3/16" Cutting Height - offers meaningful cutting depth for plunge work in dimensional lumber, sheet goods, and wall materials, making it suitable for door casing undercuts and recessed plunge slots.
- Short and Very Narrow 3/8" Blade Shape - ideal for tight groove work where a wider blade would damage surrounding surfaces or simply not fit.
- 5-Piece Pack - keeps replacements on hand so work continues without interruption, lowering per-blade cost on extended projects.
- Extremely Robust BIM Long-Life Design - resists wear in abrasive materials including porous cement and plasterboard, reducing blade swap frequency on mixed-material jobs.
Why This Product
- The narrow 3/8" blade profile solves a common problem on renovation sites - cutting in restricted spaces such as under door casings or inside grooves where standard-width blades cause collateral damage.
- BIM construction allows the same blade to transition between clean wood cuts and nail-embedded lumber (nails up to 5mm diameter) without requiring a tool change, saving time on demo and rough carpentry work.
- Starlock arbor compatibility ensures a firm, wobble-free connection to Starlock oscillating multi-tools, which translates directly to straighter, cleaner plunge cuts and less surface tear-out.
- The 5-piece quantity means a full set of fresh blades is available for larger projects or repeated daily use, making this pack a cost-effective option for contractors who rely on oscillating tools as part of their standard workflow.

Frequently Asked Questions
What oscillating tools are compatible with this blade?
This blade uses a Starlock (SL) arbor interface. It is compatible with any oscillating multi-tool that accepts the Starlock arbor system, including Starlock-compatible tools from CMT, Metabo, and other brands that support this mounting standard.
Can this blade cut through nails?
Yes. The BIM bi-metal construction allows cutting through wood with embedded nails up to 5mm in diameter. This makes it well suited for demolition work, removing door casings, and cutting through framing lumber where fasteners may be present.
Why choose a 3/8" narrow blade over a wider oscillating blade?
The short and very narrow 3/8" shape is specifically engineered for tight groove work and confined cutting areas. In situations where a wider blade would damage surrounding material or physically not fit - such as undercutting a door jamb or plunge-cutting inside a narrow slot - the 3/8" width provides the necessary clearance.
What materials can this blade cut besides wood?
In addition to wood and wood with embedded nails, this blade is rated for use on porous cement, plasterboard, and plastics, making it a versatile choice for mixed-material renovation and remodeling applications.
