Jet jt9-708814 Planer Knives 16 Inches Set of 3

Product Description

The JET jt9-708814 is a set of three replacement planer knives designed for use in 16-inch thickness planers. These high-speed cutting blades mount in the cutterhead and are responsible for stock removal and surface finishing on dimensional lumber and engineered wood. When knives wear, dull, or chip, surface quality drops and feed resistance increases. Replacing them as a matched set restores consistent cut depth and balanced cutterhead rotation. This set is the correct replacement for JET planer models that accept 16-inch knives and is installed by woodworking machinery technicians or experienced shop personnel.

These planer knives are suited for stationary thickness planer applications in woodworking shops, cabinet shops, millwork operations, and production environments. The 16-inch blade length matches full-width capacity planers in that size class. All three knives should be replaced simultaneously to maintain cutterhead balance. Uneven knife heights or mixing new and worn blades can cause snipe, chatter, or uneven surface finish across the workpiece width.

Key Features

• Set of 3 matched replacement knives for balanced cutterhead performance
• 16-inch blade length matches full-width cutting capacity of compatible planers
• OEM-style replacement for maintaining factory cut quality
• Restores stock removal efficiency when existing knives are dull or chipped
• Sold as a complete set to support proper balanced installation

Compatibility

Designed as an OEM-style replacement for JET thickness planers that accept 16-inch planer knives. Confirm cutterhead knife slot count and knife dimensions against your machine specifications before ordering.

Installation Notes

Planer knife replacement should be performed by a qualified technician familiar with woodworking machinery. Disconnect and lock out electrical power to the planer before opening the cutterhead guard or handling knives. All three knives must be set to equal projection height using a knife-setting gauge to ensure proper cutterhead balance. Failure to balance the cutterhead can cause vibration and premature bearing wear.
