Product Description
CMT TCT Knives for Portable Planers - 82x29x3mm, 2-Pack are tungsten carbide-tipped replacement blades engineered for use with a wide range of portable electric planers. Designed to fit machines including the Bosch GHO20-82, Black and Decker DN710 and DB711, Makita 1900B, 1923B, 1100, 1901, and Ryobi portable planers, these 82mm planer knives deliver clean, consistent material removal in demanding woodworking and jobsite applications. Each pack contains 2 precision-ground carbide knives sized at 82x29x3mm for direct-fit installation.
Key Features
- Tungsten Carbide-Tipped (TCT) Cutting Edge - harder and more wear-resistant than standard steel blades, so the knives hold a sharp edge longer through repetitive planing passes on hardwood, softwood, and other demanding materials.
- 82x29x3mm Knife Dimensions - matches OEM specifications for compatible portable planers, allowing a straightforward drop-in replacement without modification or shimming.
- HW Carbide Material Grade - a hard-metal (HW) grade carbide formulation that balances toughness and hardness, making it well suited for general-purpose surface planing across a range of wood species.
- Compatible with Multiple Planer Models - fits Bosch GHO20-82, Black and Decker DN710 and DB711, Makita 1900B, 1923B, 1100, 1901, and Ryobi portable planers, giving tradespeople and woodworkers a single replacement knife solution for several common tools.
- 2-Piece Pack - includes both knives needed to fully replace the cutting set in a compatible planer, so the tool is ready to return to service immediately after installation.
- 29mm Cutting Depth - the usable cutting width of each knife supports the full-width planing capacity of compatible portable planers, ensuring complete coverage across each pass.
- 3mm Knife Thickness - consistent thickness across both knives ensures proper seating in the planer head and accurate depth-of-cut performance during use.
Why This Product
- If your Bosch GHO20-82, Makita 1900B, 1901, 1923B, or 1100 portable planer has started tearing or roughing the wood surface instead of leaving a smooth finish, these TCT knives are a direct-fit replacement that restores cutting performance without any modifications.
- The tungsten carbide-tipped construction means these blades outlast conventional high-speed steel knives in hard use, reducing how often you need to stop work and swap blades on the job.
- With both knives included in a single pack, you have everything required to complete a full blade change - no need to source individual knives or order separate components.
- The 82x29x3mm dimensions are verified against multiple popular portable planer models from Bosch, Black and Decker, Makita, and Ryobi, making these a practical stock item for shops and contractors who work with more than one of these machines.

Frequently Asked Questions
Which portable planer models are these knives compatible with?
These 82x29x3mm TCT knives are compatible with the Bosch GHO20-82, Black and Decker DN710 and DB711, Makita 1900B, 1923B, 1100, and 1901, as well as Ryobi portable planers. Always confirm your specific model's knife dimensions before installing.
What does "TCT" or "HW" mean for planer knife material?
TCT stands for Tungsten Carbide-Tipped, and HW refers to the hard-metal carbide grade used in these knives. This material is significantly harder than standard steel, which means the cutting edge retains its sharpness longer and handles demanding wood species more effectively than conventional planer blades.
How many knives come in this pack, and is that enough for a full blade change?
Each pack contains 2 TCT planer knives. Most compatible portable planers in this size category use two knives in the cutter head, so this pack provides everything needed for a complete blade replacement.
What are the exact knife dimensions, and why do they matter for fit?
The knives measure 82mm in total length, 29mm in cutting depth, and 3mm in thickness. These dimensions must match the planer's cutter head slot specifications precisely - an incorrect thickness or length can affect blade seating and cutting depth accuracy, so verifying your planer's OEM knife dimensions before installation is recommended.
