CMT Reversible Throwaway Knives in Carbide - 10-Pack (1-3/16" x 31/64" x 1/16") are precision-ground indexable insert knives engineered for spindle moulders, profile machines, and compatible cutter head systems. Each knife in this 10-pack is manufactured from K1920 carbide - a high-performance tungsten carbide grade - and features two cutting edges ground to a 35 deg. bevel angle, giving woodworkers a fresh, sharp edge simply by rotating the insert rather than resharpening. These reversible carbide insert knives are a smart, cost-effective solution for high-volume wood moulding, profiling, and edge-shaping operations on hardwood, softwood, MDF, and engineered panel products.

Key Features

• K1920 carbide material - a robust tungsten carbide grade that delivers extended cutting life and resists wear on dense hardwoods, abrasive MDF, chipboard, plywood, and softwoods, reducing downtime from frequent blade changes.
• 2 cutting edges per knife at 35 deg. bevel angle - each knife can be indexed to a second fresh edge when the first dulls, effectively doubling the usable life of every insert and lowering the per-cut cost in production environments.
• Reversible (throwaway) design - eliminates the need for resharpening equipment or offsite grinding services; simply rotate or replace the knife and resume production immediately.
• Precision dimensions: 30mm (L) x 12mm (H) x 1.5mm (K) - tight dimensional tolerances ensure consistent drop-in fit within compatible cutter heads, maintaining accurate profile registration cut after cut.
• Standard indexable knife format - conforms to established indexable insert dimensions, making these knives broadly compatible with cutter head systems that accept this standard knife size.
• 10-piece pack - a practical shop quantity that keeps a ready supply on hand, minimizing production interruptions during long runs or multi-shift operations.

Why This Product

• With two usable 35 deg. cutting edges per insert and 10 knives in every pack, you get 20 cutting edges per purchase - a high edge-per-dollar ratio that makes carbide tooling more accessible for production woodworking shops.
• The throwaway approach removes the bottleneck of sending knives out for resharpening - when an edge dulls, the knife is simply indexed or replaced, keeping spindle moulders and profile machines running with minimal interruption.
• K1920 carbide construction means these inserts hold their edge longer than standard HSS alternatives when cutting abrasive materials like MDF and chipboard, translating to fewer knife changes and more consistent surface finish over a production run.
• Standardized indexable knife dimensions (30mm x 12mm x 1.5mm) make these reversible carbide inserts a practical fit for cutter head systems designed around this common knife format, reducing the need to stock multiple proprietary knife styles.
