Professional 12-1/2" Planer Knife Lock Bar Set (71382)
Secure Blade Retention for Industrial Surfacing
The POWERTEC 71382 is a professional-grade set of 12-1/2 inch Planer Knife Lock Plates, specifically precision-engineered as a definitive replacement for high-speed benchtop planers. These lock bars are the craftsman’s choice for woodworkers who require absolute mechanical rigidity and safety in their cutterhead assembly. Designed to bridge the full width of the knife, these plates provide the uniform downward pressure needed to "lock" the blade into position, preventing the dangerous knife shifting or "pumping" that can occur with worn or deformed factory hardware.
Constructed from high-strength, industrial-grade steel, each plate in this 2-pack is precision-machined to ensure perfect flatness and weight balance across the cutterhead. This uniformity is critical for eliminating unwanted harmonic vibrations and chatter, ensuring your planer delivers a glass-smooth finish on hardwoods and softwoods alike. Whether you are rebuilding a Delta 22-560 or performing routine maintenance on a Porter Cable unit, these replacement lock plates deliver the axial stability and industrial-standard durability required for showroom-quality results.
- Precision Steel Build: Heavy-duty construction resists bending and warping under high-torque fastening.
- Vibration Dampening: Precision-fit dimensions help stabilize the cutterhead to reduce surface scalloping.
- Direct OEM Replacement: Engineered to replace Porter Cable 1342143 and other standard 12.5" lock bars.
- Enhanced Safety: Provides a superior mechanical grip on planer knives to prevent accidental ejection during high-RPM use.
- Long-Term Durability: High-grade steel resists corrosion and the mechanical fatigue of frequent blade changes.
