Freud RP-A Performance System Raised Panel Knife is purpose-built for cabinetmakers who demand precise, clean openings in raised panel work. This knife is specifically designed to raise 5/8" thick panels with a 1/4" tongue, delivering a crisp profile with minimal tear-out on cross grain cuts. When you need to push into thicker doors, you can expand your capability by pairing the RP-A with optional back cutters RP-OPS or RP-OPB to tackle 3/4" panels. This modular approach lets you adapt to different panel heights without swapping to an entirely new knife, keeping your workflow efficient and accurate. Key to its performance is the knife geometry, which is engineered to remove splinters on cross grain cuts. The result is smoother edges right from the router, reducing sanding time and delivering a more professional finish straight off the machine. < h2 >Core advantages

• 5/8" panel raising with a 1/4" tongue for classic raised panel profiles
• Optional RP-OPS or RP-OPB back cutters to reach 3/4" panel thickness
• Splinter-free results on cross grain cuts for cleaner faces and tighter tolerances
• Part of Freud/Diablo RP-A Performance System, designed for reliable, repeatable results

< h2 >Ideal applications

• Raised panel cabinet doors in kitchens, bathrooms, and offices
• Shaker and traditional panel constructions where precise tongue-and-groove profiles matter
• Furniture panels and inset elements that require crisp edges and consistent dimensions

< h2 >Who benefits most

Professional cabinetmakers, woodworking shops, and ambitious hobbyists who require durable, high-precision raised panel knives that pair with compatible back cutters for flexible thickness options.

< h2 >Practical guidance for best results

• Use the RP-A for 5/8" panels with 1/4" tongues; add RP-OPS or RP-OPB back cutters when working up to 3/4" panels
• Ensure precise alignment and proper depth of cut to maximize splinter-free performance on cross grain cuts
• Test on scrap material to dial in pressure, feed rate, and cutting depth before final production
• Keep the knife sharp and periodically inspect for wear to maintain edge quality and clean profiles
