CMT Reversible Throwaway Knives - Carbide 20x12x1.5mm (10-Pack) are precision-ground solid carbide insert knives engineered for demanding woodworking applications. Built from K1920 tungsten carbide, these 2-cutting-edge indexable knives feature a 35 deg. bevel angle and a compact 20x12x1.5mm profile that fits a wide range of cutter head systems used on spindle moulders, profile machines, and edging machines. With two usable cutting edges per insert, each knife delivers extended productivity before replacement is needed - making this 10-pack a practical and cost-effective solution for production and shop environments alike.

Key Features

• K1920 Tungsten Carbide Material - provides exceptional hardness and wear resistance, allowing these insert knives to handle hardwood, softwood, MDF, chipboard, and plywood without rapid dulling.
• 2 Cutting Edges at 35 deg. Bevel - each knife is reversible, giving you two sharp edges per insert so you can rotate to a fresh edge when one dulls and extend the working life of each piece before disposal.
• Precision Dimensions: 20mm Length x 12mm Height x 1.5mm Thickness - ground to exact tolerances for consistent seating in compatible insert cutter heads, resulting in repeatable profile quality across every pass.
• Indexable Throwaway Design - when both cutting edges are spent, the knife is simply discarded, eliminating sharpening time and keeping downtime minimal in production settings.
• 10-Pack Quantity - stocking a full pack ensures you have replacement inserts on hand to maintain uninterrupted workflow without delays waiting for additional tooling.
• Standard Reversible Knife Format - compatible with insert shaper cutter head systems designed to accept this knife profile, offering broad versatility across spindle moulders, router table cutter heads, and profile machines.

Why This Product

• Two edges mean more cuts per insert - the reversible design means you are not discarding a knife after a single side wears down. Rotating to the second 35 deg. cutting edge effectively doubles your mileage from every knife in the pack.
• K1920 carbide holds an edge longer than standard high-speed steel alternatives - for shops processing hardwood, MDF, or abrasive composite materials regularly, carbide inserts reduce the frequency of knife changes and maintain cut quality longer.
• Throwaway inserts eliminate the sharpening step entirely - in production environments where grinding time costs money, a fresh indexable carbide edge is faster to deploy than returning a knife to a grinder, keeping machines running.
• A pack of 10 inserts keeps your cutter head supplied - having a ready inventory of matched 20x12x1.5mm knives means you can change all seats in a multi-knife cutter head at once, preserving balance and cut consistency.
