CMT Solid Carbide Reversible Insert Knives - R2 Radius, 12x12x1.5mm, 4 Cutting Edges (10-Pack) are precision-ground tungsten carbide insert knives engineered for demanding profiling and molding work on spindle moulders, profile machines, and router tables equipped with compatible cutter heads. Each square insert knife measures 12x12x1.5mm with a 2mm radius profile and features four usable cutting edges, so when one edge wears, you simply rotate to a fresh edge and keep cutting - maximizing uptime and stretching the value of every knife in the pack. The 35 deg. cutting angle and F1730-grade solid carbide construction deliver clean, consistent results across hardwood, softwood, MDF, chipboard, and plywood.

Key Features

• F1730 Solid Carbide (Tungsten Carbide) Construction - this high-grade carbide material resists heat and wear far longer than HSS alternatives, making it the right choice for high-volume work in hardwood, softwood, MDF, and engineered sheet goods.
• 4 Cutting Edges Per Insert - the square reversible design gives you four usable edges from a single knife, reducing replacement frequency and lowering the per-edge cost significantly compared to single-edge tooling.
• R2 (2mm Radius) Profile - the precise 2mm radius delivers consistent, repeatable edge profiling, rabbeting, and molding passes on every workpiece, eliminating guesswork during setup.
• 12x12x1.5mm Dimensions with 35 deg. Cutting Angle - the compact square geometry combined with a 35 deg. angle provides a controlled, efficient cut that reduces chipping and tear-out on both solid wood and composite materials.
• 1.5mm Thickness - the thin knife profile seats securely in compatible cutter head pockets, ensuring stable registration and repeatable profile accuracy from pass to pass.
• 10-Piece Pack - stocking 10 knives at once means fewer interruptions to your workflow - keep fresh inserts on hand and swap quickly without waiting on reorders during a production run.
• Precision Ground to Exact Tolerances - each knife is ground to tight dimensional tolerances, so every insert produces the same profile quality whether it is the first knife in the pack or the last.

Why This Product

• Four edges mean four times the cutting life before replacement - for shops running spindle moulders or profile machines continuously, the reversible insert design keeps the cutter head in service longer and reduces downtime between tool changes.
• Solid carbide construction handles the full range of wood-based panel products - from solid hardwood to MDF and chipboard, the F1730 carbide grade maintains a sharp, clean edge through materials that quickly dull lower-grade tooling.
• The R2 radius profile covers a wide range of common joinery and decorative molding operations - rabbeting, edge profiling, grooving, and jointing are all achievable with a single insert geometry, reducing the number of knife sets needed in the shop.
• Buying in a 10-pack ensures you always have a ready supply of matched inserts - all 10 knives share identical dimensions and tolerances, so they can be mixed and matched within the same cutter head without sacrificing balance or profile consistency.
