Features

Expanded Faceplate/Limiting Surface

Provides superior cant control, minimizing surging and reducing step cutting on entry.

Smooth & Open Chip Channel

Improves chip quality by providing chips an unobstructed path to exit the system.

Fixed Knives

Knives are fixed to ensure a repeatable cut, and to reduce maintenance.

Ridge Knife XL

The knife is indexible and disposable, eliminating the need for grinding and babbitting. The innovative ridge design eliminates problematic packing, protects the counter knife from wear, and improves chip quality by providing chips a smooth transition from knife tip to counterknife.

Five Point Knife Clamping

The innovative design of the Ridge XL Knife, Clamp, and Counterknife system produces 5 point knife clamping. 5 point knife clamping significantly improves knife stability, for a precise and repeatable cut.

Extra Options

Pre-Cutting Saw

The pre-cutting saw provides a sawn finish with little to no knot pull out or fiber pull for a superior finish. Key Knife uses a ring saw configuration to keep weight down, as well as cost. The saw is universal for both right and left chipping heads.

Post-Cutting Saw

The post cutting saw follows the finishing knife to clean up the cut for a sawn finish. Because the entire width of the saw face is not used (approximately .015”) less sawdust is produced, and recovery is maximized. Key Knife uses a ring saw configuration to keep weight down, as well as cost. The saw is universal for both right and left chipping heads.
