Square carbide insert knives or turnover knives are cutting tools commonly used in woodworking for planing, moulding, and finishing. They are small square pieces of tungsten carbide mounted onto various cutterheads. Tungsten carbide, as a perfect raw material for manufacturing the insert knife, is extremely hard and durable and is resistant to wear and high temperature. Square carbide insert knives are generally attached to cutterheads by using screws or clamps, allowing for easy replacement when one edge is dull.
