HY2 is the toughest, most advanced indexible knife drum head chipping system available. Key Knife’s next generation drum style chipping head and knife system, the HY2 (High Yield 2), is the solution for progressive sawmills that are looking to improve surface finish, chip quality, and operating efficiencies. It is designed and built to perform in the most challenging operating environments around the world.  The advantages of the HY2  are:

• Improved lumber recovery and surface finish with reduced damage to the cant through a consistent tight tolerance cut that minimizes scalloping, fiber pull, and knot tear out
• Reduced cant sticking with the HY2’s ability to make a precise and repeatable cut
• Improved chip quality  with HY2’s innovative clamping design that ensures the knife-edge stays firmly in place for a clean and precise cut
• Improved chip flow with larger and smoother gullets to minimize the break up of quality chips into pins and fines
• Increased efficiency with the unique design of the Ridge XL Knife giving you the flexibility to run longer between knife changes
• Quick and safe knife changes - simply loosen the clamp bolt, seat the Ridge Knife XL on the counterknife, and tighten the clamp bolt
