Planer Blade Setter Gages Electric Planer Blade Adjustment Fixture Installer

When planer knives sit at uneven heights, boards come off the machine with snipe, chatter marks or a stepped finish that no amount of feed tuning will fix. Resetting knives by eye or with a straight edge leaves the same error in place after every knife change.

This is a planer blade setter gage, a woodwork machine tool for knife adjustment on planer and jointer machines. It comes in black and is packed 2pcs per carton. The gage works as a blade holder reference during setup.

Mount the gage on the cutterhead so its reference face sits against the knife edge, then adjust each knife until it meets the gage. Do this across the full length of the knife, not just at one point.

Supply is 2pcs per carton in black. No customisation, voltage or lead time is stated here, so ask about those separately. When you enquire, send your planer or jointer model, cutterhead diameter, knife slot width, and the number of knives in the cutterhead. Those details let the supplier confirm the gage suits your machine before you commit.

A setter gage gives you a repeatable reference for knife height so each knife goes back in the same position.

What the specification fixes, and what it leaves to the machine:

• Knife height reference — The gage gives a fixed reference face for setting each planer knife to the same height across the cutterhead.
• Blade holder contact — Use it as a blade holder reference during adjustment so the knife stays put while you tighten the locking screws.
• Planer and jointer use — It is intended for knife adjustment on woodworking planer and jointer machines, not for other machine types.
• Black finish — The gage is supplied in black, which keeps the reference edges easy to see against bright knife steel.
• Two-piece carton — Each carton holds 2pcs, so you have a spare gage or a second reference for a two-knife cutterhead.
• Accuracy feature — High accuracy is a stated feature, which matters when knife height error shows up as chatter or snipe on the board.
• Durability feature — Durability is a stated feature, which matters because the gage is handled at every knife change and must hold its reference.
• Adjustment workflow — The tool supports the knife adjustment step, so you set height before locking and cut fewer test boards.
• Cutterhead fit check — Check the gage against your cutterhead diameter and knife slot width before ordering to confirm it suits your machine.

What changes on the shop floor when the right part goes back in:

• Repeatable knife height. A fixed reference face means each knife goes back to the same height after sharpening or replacement, so you spend less time chasing snipe and chatter with test cuts.
• Fewer test boards. With a reference to set height before locking, you cut fewer scrap boards checking the finish, which saves stock and shop time on every knife change.
• Consistent knife set. Setting every knife against the same gage keeps the full set at one height, so the cutterhead cuts evenly across the full width of the board.
• Spare in the carton. Two pieces per carton give you a spare gage or a second reference point, so a dropped or misplaced gage does not stop a knife change.
• Visible reference. The black finish keeps the gage edges easy to see against bright knife steel, so you can check contact along the knife without straining.
• Fits planer and jointer. The gage is intended for both planer and jointer knife adjustment, so one tool covers the knife setup work on both machines in the shop.
• Fit confirmed before order. Sending your machine model and knife dimensions with the enquiry lets the gage be checked against your cutterhead before you commit to the order.
