IGM Magnetic Knife Setting Jig is a set of 2 magnetic gauges for precise knife adjustment in the cutterblock of planers and thicknessers. Each gauge is equipped with a micrometric scale for uniform depth adjustment on both sides of the knife. Distributed in Italy by Krollit, official IGM distributor since 2007.
- Package contents: 2 magnetic gauges
- Use: knife adjustment in planers and thicknessers
- Fixing: magnetic on the cutterblock
- Scale: micrometric for uniform depth adjustment
- Pieces per set: 2, one for each side of the knife
Who the IGM magnetic gauge is suitable for
| Profile |
Compatibility |
Reason |
| Woodworker who frequently adjusts or replaces knives |
Suitable |
The micrometric scale allows the knives to be repositioned at the same height every time, reducing setup time |
| Workshop with jointer or thickness planer |
Suitable |
The 2 gauges allow simultaneous adjustment of both ends of the knife for uniform depth |
| Non-ferromagnetic cutterblocks |
Not suitable |
The fixing is magnetic, so it does not work on aluminum cutterblocks or non-ferrous materials |
Not suitable for: helical cutterblocks or systems with reversible inserts, where adjustment is carried out with a dedicated mechanical locking system and does not require external gauges.

Frequently Asked Questions
How does adjustment with the IGM magnetic gauges work?
The gauges attach magnetically to the cutterblock. The knife is raised until it touches the reference surface of the gauge, then locked in place. The micrometric scale allows the same height to be set on both sides, achieving a uniform cutting depth across the entire length of the knife.
Are these gauges compatible with all planers?
The fixing is magnetic, so the gauges work on steel or cast iron cutterblocks. They are not compatible with aluminum cutterblocks or other non-ferromagnetic materials. Before purchasing, check the material of your machine’s cutterblock.
Why does the set include 2 gauges instead of just one?
A planer knife must be adjusted at both ends at the same time to ensure a uniform depth across the entire working width. With only one gauge, there is a risk of introducing a height difference between the two sides, causing uneven planing marks on the workpiece.
Are they also compatible with thicknessers as well as jointers?
Yes, the operating principle is the same on jointers and thicknessers, provided that the cutterblock is ferromagnetic. On combined jointer-thicknesser machines, the set covers both functions with a single purchase.
Where can I buy compatible IGM replacement knives?
Krollit stocks original IGM replacement knives for the main planer models. Contact +39 0825-1494022 and indicate the model and working width of your machine.
