This is a brand-new, OEM riving knife with part number 089240028705, exclusively engineered for the R4514 and R4514T table saws. As the core anti-kickback safety component of the table saw, it is mounted directly rear of the saw blade and moves synchronously with it during cutting operations. It serves the critical functions of separating the split wood workpiece from the rotating saw blade, preventing the workpiece from pinching the blade due to natural wood shrinkage, warpage or tension, and effectively eliminating the dangerous kickback phenomenon that may cause severe operational accidents. Meanwhile, it guides the wood workpiece to move along a fixed and straight cutting track, ensuring smooth, precise and straight cutting effects for wood boards, panels and other wooden materials, and is an indispensable safety and maintenance accessory for ensuring the standardized and safe operation of the table saw in woodworking cutting, furniture manufacturing, home decoration and wood board processing scenarios.

Crafted from high-strength, wear-resistant and high-toughness metal steel through precision forging, CNC machining and surface hardening treatment, the riving knife boasts excellent structural firmness, impact resistance and wear resistance. It can withstand continuous impact and friction from wooden workpieces during high-speed cutting without easy bending, deformation, wear or fracture, and its precisely calibrated dimensional design perfectly matches the thickness and cutting path of the original saw blade, achieving effective workpiece separation without interfering with the normal lifting, tilting and cutting movement of the saw blade. Its precision-machined mounting and linkage structure is a perfect match for the original saw body and blade adjustment system of the R4514/R4514T table saws, enabling synchronous lifting and angle adjustment with the saw blade, maintaining accurate alignment with the blade at all times, and featuring tight and stable fixation with no shaking, loosening or displacement during the high-speed operation of the equipment. Adopting a direct-fit installation design with no modification or secondary processing required, it can be quickly assembled and fixed to the saw body with simple operation, and is an ideal original replacement for worn, bent, deformed or damaged original riving knives that lead to poor anti-kickback performance, unstable cutting and potential safety hazards. Installing this component restores the reliable anti-kickback safety performance and precise cutting guiding effect of the R4514/R4514T table saw, making it a necessary safety maintenance part for all types of woodworking cutting operations of the table saw.
