CMT Metrik Knives 9-1/16" x 1-3/16" x 1/8" are precision planer and jointer blades engineered for woodworkers who demand consistent, smooth stock removal from hardwoods, softwoods, and plywood alike. Manufactured from HSS (High-Speed Steel) and milled to balanced tolerances, these 230 x 30 x 3 mm replacement knives deliver reliable, flat cuts on stationary planers and jointers. Sold as a 2-piece matched pair, they are ready to drop in as a balanced set for symmetrical, chatter-free performance across demanding shop applications.

Key Features

• HSS (High-Speed Steel) construction - high-speed steel retains its cutting edge longer than standard carbon steel, reducing the frequency of sharpening or replacement during extended planing sessions.
• Balanced and milled knives - each knife is individually milled and matched for balance, meaning the cutterhead runs smoothly without vibration, resulting in flatter surfaces and a cleaner finish on workpieces.
• Precision dimensions of 230 x 30 x 3 mm (9-1/16" x 1-3/16" x 1/8") - exact sizing ensures a proper fit in compatible cutterheads, eliminating guesswork and reducing setup time at the machine.
• 2-piece matched package - sold as a pair so both knives on a two-knife cutterhead can be replaced simultaneously, maintaining balanced cutting geometry and consistent chip removal.
• Special dimensions available on request - custom sizing options mean these knives can be adapted to non-standard cutterhead configurations beyond the standard 230 x 30 x 3 mm specification.

Why This Product

• For woodworkers running stationary planers or jointers, replacing both knives at once with a matched HSS pair eliminates the imbalance and surface inconsistency that comes from mixing worn and fresh blades.
• The HSS material and precision milling process means these knives hold a working edge through repeated passes on hardwood, softwood, and plywood - reducing downtime for mid-project sharpening.
• At exactly 230 mm in length and 3 mm in thickness, these knives conform to the Metrik standard, making them a direct fit for compatible cutterheads without modification or shimming.
• The 2-piece pack format means you always have a complete replacement set on hand - no mixing blade lots or ordering individual knives to complete a balanced pair.

Frequently Asked Questions

What material are these knives made from, and why does it matter?

These knives are manufactured from HSS (High-Speed Steel). HSS is a tool steel grade that maintains hardness and edge retention under the heat and friction generated during repeated planing passes, which means longer intervals between sharpening or replacement compared to lower-grade steels.

Why are these knives sold as a 2-piece set?

Planer and jointer cutterheads require balanced knife sets to run smoothly. Replacing both knives at once with a matched pair - as this package provides - ensures the cutterhead remains in balance, which reduces vibration, extends bearing life, and produces a more consistent, flat surface on planed workpieces.

What are the exact dimensions of these knives?

The CMT 792.230.30 Metrik knives measure 230 mm in total length, 30 mm in cutting depth, 30 mm in cutting height, and 3 mm in teeth thickness. In imperial terms, that corresponds to 9-1/16" x 1-3/16" x 1/8".

Can these knives be used on plywood as well as solid wood?

Yes. The 792.230.30 knives are suitable for use on plywood in addition to dry softwood and both dry and wet hardwood. The HSS construction and precision-milled edge make them capable of handling the varied grain directions and adhesive layers present in plywood without excessive dulling.
