Product Description
CMT 794.511 HS Planer and Jointer Knives - 20 Inch by CMT are precision-ground high speed steel cutting knives engineered for stationary planers and jointers. Carefully ground from fine European high speed steel with 13% tungsten content, these planer blades deliver consistent, smooth stock removal on dry softwood, dry hardwood, and wet hardwood alike. Whether you are surfacing rough lumber, truing up boards on a jointer, or preparing material for finish work, this 20 inch knife is sized to fit standard wide planer configurations and provides the cutting performance that woodworkers and cabinet shops depend on.
Key Features
- High Speed Steel with 13% Tungsten (HS 13%W) construction - the elevated tungsten content increases hardness and heat resistance, allowing the cutting edge to hold longer between sharpenings even under demanding production use.
- Carefully ground from fine European high speed steel - precise grinding geometry means the edge is consistent from heel to toe, reducing snipe and producing flat, uniform surfaces across the full 20 inch width.
- Suitable for dry softwood, dry hardwood, and wet hardwood - one knife handles the broad range of lumber species and moisture conditions found in a typical shop, eliminating the need to swap blades between different wood types.
- 20 inch length x 1 inch cutting height x 1/8 inch thickness - exact OEM-matching dimensions make installation straightforward and ensure proper clamping in compatible planer and jointer heads without modification.
Why This Product
- The 13% tungsten high speed steel formula resists edge breakdown during extended runs through hardwood, giving you more board footage between knife changes compared to standard HSS grades.
- Fine European steel stock and careful precision grinding mean you get a repeatable, ready-to-use cutting edge straight out of the package - no need for additional honing before the first installation.
- Compatibility with both dry and wet hardwood makes this knife a practical choice for shops processing green or kiln-dried material without needing to stock separate blades for each condition.
- At 20 inches long with a 1 inch cutting height and 1/8 inch thickness, this knife is a direct-fit replacement for wide-format planer and jointer heads that require these exact dimensions, simplifying maintenance and reducing downtime.
