M2 HSS 25″ × 1-3/4″ × 1/4″ Bar-Length Planer/Jointer Knife Bar

Description

The TN402H is a 25-inch M2 molybdenum high-speed steel bar-length planer and jointer knife bar, 1-3/4 wide and 1/4 thick. Bar-length stock allows the shop to cut individual knives to the specific length required by each machine — a 25-inch bar typically yields multiple knife sets for standard jointer and planer configurations from 4 inches to 16 inches, reducing per-knife cost compared to buying pre-cut sets. The 1-3/4-wide cross-section suits knife profiles that fit heads requiring this knife height; the 1/4 thickness must match the head’s knife slot specification precisely — confirm slot dimension before ordering. M2 HSS is a premium molybdenum-based high-speed steel alloy with greater toughness and abrasion resistance than standard T1 grades — appropriate for demanding production runs and harder species. Grind to finished profile on a standard surface grinder with appropriate HSS wheel. Used across jointer heads, planer heads, and moulder knife holders accepting 1/4-thick knife stock at 1-3/4 height.
