Descripción
Sundi’s square indexable insert knives are made from high-quality carbide, offering excellent wear resistance and clean cutting performance. Commonly used in helical cutterheads for planers and jointers, each insert is fixed with a screw or clamp and can be easily rotated or replaced when an edge becomes dull—earning them the name “reversible knives.” Ideal for cutting hardwood, softwood, plywood, MDF, and particle board, these inserts are a cost-effective choice for both mass production and precision woodworking.
With over 20 years of experience in precision cutting tools, Sundi is an ISO-certified manufacturer specializing in carbide insert knives and other woodworking solutions. Whether you’re a furniture factory owner, a woodworking machinery distributor, or a skilled hobbyist, we provide reliable products and professional support tailored to your needs.

Features:
Easy Replacement: When an edge becomes dull or chipped, simply rotate the insert to a fresh cutting edge, facilitating quick and convenient maintenance.
Premium Material: Crafted from high-quality tungsten carbide, these inserts provide exceptional hardness and durability, ensuring prolonged tool life.
Sharp Cutting Edges: The razor-sharp edges minimize wood tear-out, resulting in smoother finishes on various materials.
