A jointer flattens one face of a board and squares an edge to it, which is the first step to tight glue joints and accurate furniture. Cutting width decides how wide a board you can flatten, table length decides how long a board stays supported, and a spiral or helical cutterhead gives a cleaner finish with less tear-out than straight knives. We put 14 jointers on one spec sheet so you can compare width, cutterhead, tables, fence and weight side by side.

We reviewed 25 jointers and kept only the 14 that pass every check below. Those are ranked by a Best Score built from spec fit for this job, warranty, sales rank.
These reviews are based on each jointer's published specifications and listing information, in the order of our Best Score.
Twelve-in spiral jointer that still sits on a bench
The CUTECH 401120HI-IF leads our Best Score at 69. Its standout spec is a 12 in cutting width, tied for the widest on this page, so you can flatten wide panels and tabletop boards that a 6 in jointer cannot handle. For many hobby shops, that removes the need to rip boards narrow and glue them back.
The spiral cutterhead holds 24 staggered tungsten carbide inserts in 6 rows. Staggered inserts slice wood at an angle, which reduces tear-out in figured grain and runs quieter than straight knives. The inserts are two-sided, so you can rotate to a fresh edge when one dulls.
It has a 34 in cast iron table and a 24 in cast iron fence with quick stops at 90 and 135 degrees. CUTECH describes the 12 amp motor as the most powerful among benchtop jointers it compares against. At 111.8 lb it is heavy for a benchtop tool, so plan where it lives.
VerdictThe best all-round jointer here, giving wide-board capacity and a premium cutterhead on a bench.
Floor-standing JET with long tables for long boards
Second with a Best Score of 57, the JET JJ-6HHDX takes a different approach. It is only 6 in wide, but its precision-machined cast iron tables measure 56 in long. Long tables are what let you joint an 6 ft board straight, because the board stays supported before and after the cutterhead.
The helical cutterhead spins at 6,000 RPM with 27 four-sided carbide inserts in four staggered rows. Four-sided inserts give you four fresh edges each before replacement. It removes up to 1/8 in per pass and runs on a 1 HP motor.
The 32.75 in fence tilts 45 degrees left and right with positive stops at 45 and 90 degrees, and there is a 4 in dust port. JET notes that this helical model does not cut rabbets. At 237 lb it is a stationary machine, backed by a 5-year warranty, the longest on this page.
VerdictThe most accurate choice here for long boards, with the best warranty on the page.
WEN 12 in spiral jointer with extendable support
The WEN JT1224H ranks third with a Best Score of 52. Like the CUTECH, it cuts 12 in wide and uses a spiral cutterhead with 24 staggered blades. The difference is the blade material: WEN uses HSS blades rather than carbide, which cut cleanly but dull faster in hard woods.
Its cast iron table measures 34 by 12-3/16 in, and support arms extend the work surface to 54 in. That extra support helps when you run longer boards on a benchtop machine. It removes up to 1/8 in per pass.
The 24 by 4-1/4 in fence bevels up to 45 degrees. At 102.8 lb it is slightly lighter than the CUTECH, and it carries a 2-year warranty. If wide capacity matters most and you can accept HSS blades, it covers the same jobs as the leader.
VerdictA wide benchtop jointer with useful table extensions, one step behind the carbide CUTECH.
Eight-in spiral jointer at a manageable weight
Fourth with a Best Score of 49, the CUTECH 40180HB sits between the 6 in and 12 in machines. Its 8 in cutting width handles most furniture stock, and at 55.1 lb it is about half the weight of the 12 in benchtop models, so it is easier to lift onto a bench or store.
It uses the same CUTECH spiral design with 16 two-sided inserts in staggered rows, which CUTECH says reduces noise and gives a smooth finish. A depth of cut scale and pointer help you set accurate passes, up to 1/8 in at a time.
The trade-offs are an aluminum table instead of cast iron, and the shortest fence on this page at 19.625 in, with quick stops at 90 and 135 degrees. The table is 34 in long. Warranty is not listed in our data.
VerdictA sensible middle ground for small shops that need 8 in capacity.
Light 6 in spiral jointer for small shops
The WEN JT630H rounds out our top five with a Best Score of 46. It is a 6 in benchtop jointer weighing 36.82 lb, light enough to store on a shelf and bring out when needed. That makes it a good first jointer for a garage or apartment shop.
Its spiral cutterhead uses 12 staggered HSS blades for a fine finish, and it removes up to 1/8 in per pass. The table measures 30 by 6 in, and the 19-3/4 by 4-1/4 in fence bevels up to 45 degrees. The 10 amp motor suits edge jointing and flattening narrow boards.
Short tables mean long boards are harder to joint straight, so it is best for boards a few feet long. Table material is not listed in our data. It carries a 2-year warranty, matching the larger WEN.
VerdictA compact, affordable way to get a spiral cutterhead into a small shop.
Best among the reviewed tools
A jointer can only flatten boards as wide as its cutterhead. The models here range from 6 in to 12 in. If you build tabletops or wide panels, a 12 in machine saves you ripping and regluing boards.
The longer the infeed and outfeed tables, the longer the board you can joint accurately. Tables here run from 23 in to 73 in. Benchtop jointers with short tables suit boards a few feet long.
Spiral and helical heads use many small inserts set at an angle. They leave a smoother surface in tricky grain, run quieter and let you rotate inserts instead of resetting long knives. Carbide inserts last longer than HSS.
Benchtop jointers weigh from about 21 lb to 112 lb and fit small shops. Stationary machines like the JET JJ-6HHDX and Powermatic 60HH weigh hundreds of pounds but give longer tables and more stability.
A 6 in jointer handles edges and narrow boards for most furniture. An 8 in jointer covers wider stock. If you flatten wide panels or tabletop boards, a 12 in benchtop model avoids ripping and regluing.
For most woodworkers, yes. Spiral and helical heads reduce tear-out in figured wood, run quieter and make blade changes easier because you rotate small inserts instead of setting long knives.
It can, but short tables make it harder to keep long boards straight. Use roller stands or extension arms for support, or choose a machine with longer tables if you often joint boards over 4 ft.
A jointer flattens one face and squares one edge. A planer then makes the opposite face parallel and sets thickness. Together they turn rough lumber into square, flat stock.
