CMT 3/8" Plunge Cut Blade for Wood and Nails - BIM Starlock (50-Piece) is a professional-grade bi-metal oscillating blade engineered for plunge cutting and flush cutting in wood, wood with embedded nails, porous cement, plasterboard, and plastics. The narrow 3/8" profile makes this blade a go-to choice for tight groove work and confined spaces where wider blades simply cannot maneuver. Supplied in a contractor-friendly 50-piece bulk pack, this Starlock-compatible blade is built for high-volume use on multi-tool applications where durability and precision are equally critical.

Key Features

• Starlock Arbor Interface: the Starlock mounting system delivers a secure, tool-free blade connection that transfers more power from the oscillating tool to the blade - resulting in faster cuts and reduced slipping during demanding applications.
• Bi-Metal (BIM) Construction: hard high-speed steel teeth are bonded to a flexible spring-steel body, combining cutting edge toughness with body flexibility - this is what allows the blade to handle wood with embedded nails up to 5mm diameter without snapping or premature dulling.
• 3/8" (10mm) Narrow Blade Width: the short and very narrow shape is specifically designed for tight groove work and precision plunge cuts in confined areas where standard-width blades cannot reach.
• 1-3/16" Cutting Height: provides meaningful depth per stroke so plunge and flush-cut tasks can be completed with fewer passes, improving job site efficiency.
• 1.4 TS - 18 TPI Tooth Configuration: the tooth geometry is optimized for clean, aggressive cutting in wood and nail-embedded materials, reducing tear-out while maintaining a fast cut rate.
• Multi-Material Versatility: rated for wood, wood with embedded nails, porous cement, plasterboard, and plastics - one blade handles multiple substrates on a single job site, reducing the need for frequent blade swaps.
• 50-Piece Bulk Pack: the high-quantity pack is designed for contractors and professional users who demand a ready supply of fresh blades to maintain uninterrupted workflow on larger projects.
• Extremely Robust Long-Life Design: CMT engineered this blade for extended service life in demanding conditions, which means fewer stoppages for blade replacement and lower cost-per-cut over time.

Why This Product

• Handles Nails Without Stopping: unlike standard wood-only oscillating blades, the BIM construction allows cutting through wood with embedded nails up to 5mm diameter - ideal for demolition, renovation, and remodeling work where hidden fasteners are common.
• Built for Tight Spaces: the short and very narrow 3/8" blade profile was purposefully designed for groove work and flush cuts in confined spots that standard blades cannot access, making it a practical choice for trim work, door casing removal, and similar precision tasks.
• Broad Surface Compatibility in One Blade: coverage across wood, nail-embedded lumber, porous cement, plasterboard, and plastics means a single blade type can carry a jobsite through multiple material types without requiring a full kit of specialized blades.
• 50-Piece Pack Reduces Downtime: having 50 blades on hand ensures a replacement is always within reach, keeping crews productive on high-volume or multi-stage projects without waiting on resupply.
