Product Description
The CMT792 Magnetic Knife Setting Jigs are a professional-grade set of 2 jigs designed to take the guesswork out of knife alignment in planers and jointers. By using integrated magnets to hold each knife firmly in place during the setting process, these jigs allow woodworkers to make perfect micro adjustments that directly translate into smoother cuts, cleaner surfaces, and consistent cutting performance across every pass. Whether you are tuning a planer for production work or dialing in a jointer for finish-quality results, this knife setting tool set delivers the precision alignment that professional and serious hobby woodworkers demand.
Key Features
- Magnetic knife retention - holds each knife securely inside the tool holder without slipping, so you can make controlled, repeatable adjustments without the knife shifting mid-setup.
- Perfect micro adjustment capability - enables fine-tuned knife height alignment that would be difficult to achieve by hand, directly guaranteeing excellent cutting performance and surface finish quality.
- Set of 2 jigs included - having two jigs in the set means you can simultaneously reference and align multiple knives, saving setup time and ensuring every knife in the cutterhead sits at the same precise height.
Why This Product
- Eliminates inconsistent knife height - when planer or jointer knives are set unevenly, one knife does more work than the others, causing chatter, ridges, and premature wear. These jigs solve that problem by making uniform knife height achievable on every setup.
- Micro adjustment precision means better results - rough or approximate knife setting produces torn grain and uneven surfaces. The magnetic jigs enable the kind of fine-tuned positioning that produces genuinely smooth, accurate cuts.
- Two-jig set for efficient setup - using a single jig at a time can introduce small errors as you move between knife positions. Having 2 jigs lets you verify alignment across the full width of your cutterhead simultaneously.
- Straightforward workflow compatibility - the magnetic design integrates directly with standard knife-style tool holders, making these jigs a practical upgrade to your existing planer or jointer knife change routine without requiring additional hardware.

Frequently Asked Questions
What is included in the CMT792 set?
The CMT792 includes a set of 2 magnetic knife setting jigs. Both jigs are identical in function and are intended to be used together during the knife alignment process so that all knives in a cutterhead can be set to a uniform, consistent height.
What types of machines are these knife setting jigs designed for?
These magnetic knife setting jigs are designed for use with planer and jointer machines that use traditional straight knife-style cutterheads. They are suited for knife alignment and height-setting tasks on both machine types.
How do the magnets help during knife installation?
The magnets hold each knife securely against the jig surface while you position and lock it into the tool holder. This prevents the knife from shifting or dropping during adjustment, allowing you to make precise micro adjustments with confidence before fully tightening the knife in place.
Why does accurate knife height setting matter for cutting performance?
When knives in a cutterhead are set at different heights, only the highest knife does most of the cutting, which causes uneven surfaces, increased tear-out, and faster knife wear. Setting all knives to the same height using a precision jig like the CMT792 ensures balanced cutting load and excellent surface finish quality.
