We offer a great selection of 2-sided tersa planer knives for optimized performance and longer tool life with your planer.  Choose from top quality Tersa Planer knives in M2 HSS, M42 Steel, or Premium Carbide.  All our Tersa planer knives have a 10mm width and 2mm thickness. 

The M2 HSS is a High Speed Steel material that can endure higher temperaturs, allowing it to cut faster, and lasts much longer than carbon steel knives.  The M2 HSS Tersa Planer knives are recommended for softer woods like Cedar, Pine, Fir, etc.  For Harder woods like Maple, Birch, Oak and Cherry, use the M42 Steel Tersa Planer knives.  Use Carbide for even longer tool life and faster cutting in hardwoods.
