Corrugated 2 pc Carbide Knife Systems

Knife-Lock is a high precision carbide moulder knife system for millwork manufactures who cut glue lines, hardwoods, and MDF. The carbide knife locks and indexes up on a corrugated HSS backing support plate as it is resharpened. Polished to a mirror finish, out C3 Micro Grain carbide knives offer finer material wood finsihes and longer production runs while providing longer diamond grinding wheel wear.

The backing plates are a one time purchase, only replacement carbide knives are needed as they are sharpened away. Our carbide knives are also 100% compatible with your existing backing plates. Knives and backing plates are CNC ground on creep feed crush grinders for precise locking, closer balance tolerances from knife to knife, and less initial grinding. For best results grind our Knife Lock System with our Premium CBN, CDX and Diamond Super Abrasive Wheels

Knives are now offered with an optional "Thin Film Diamond Coating" (PCD-CVD) for 30% more- increases wear life up to 4 times. Compare our price, selection, quality, and our responsive order delivery and you will see why so many MDF millworkers use Knife-Lock.
