- Cutterhead type
- helical
A helical cutterhead replaces two or three long knives with rows of small carbide or steel inserts set at an angle. The inserts shear the wood instead of chopping it, which means less tear-out in figured and reversing grain, quieter running and easy maintenance: when an insert dulls or chips, you rotate it to a fresh edge instead of replacing a whole knife. Width, power, weight and snipe control still decide which planer fits your shop. We put 7 helical cutterhead planers on one spec sheet so you can compare them side by side.

We reviewed 28 benchtop planers and kept only the 7 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 planer's published specifications and listing information, in the order of our Best Score.
FindBuyTool MB320, a light benchtop with carbide inserts
The FindBuyTool MB320 leads our Best Score at 66. It has a pre-installed 4-row helical cutterhead with 40 tungsten carbide inserts that shear-cut hardwood and softwood smoothly with low operating noise. Carbide inserts last far longer than high speed steel.
A 120V 15A motor reaches 20,000 RPM, and the feed rate is 27.5 FPM. Built-in overload protection shuts it off if the motor is strained. A 4-column design and anti-wobble cast-aluminum base keep the head steady, and FindBuyTool lists thickness tolerance under 0.1 mm.
Eight depth-stop settings let you plane a batch of boards to the same thickness, and folding extension boards support longer stock. At 70 lb it is the lightest planer on this page, so it can be stored and lifted onto a bench. It planes boards up to 13 in wide. For a benchtop helical planer on a 120V outlet, it is the best fit here.
VerdictThe best benchtop helical planer on this page.
JET 20 in helical planer for serious shops
Second with a Best Score of 60, the JET JWP-208HH is not a benchtop machine but a full stationary planer. It ranks here because of its capacity: 20 in wide and 8 in thick, the largest on this page, with a 68-insert helical cutterhead.
A 5-HP TEFC induction motor drives the head through a V-belt, and it needs 230V single phase power. A one-piece welded steel base offers solid support, and a large handwheel with positive gear drive gives quick, accurate table adjustments. A 1/16-in increment height scale helps with fine cuts.
It has a dust port, and it is a heavy floor machine that needs a permanent spot and dust collection sized for its chip output. For shops planing wide slabs and tabletop boards, it is a big step up from any benchtop planer. If you only have 120V power or limited space, look at the benchtop picks instead.
VerdictA serious stationary option for wide boards.
JET 15 in helical planer with snipe control
The JET JWP-15BHH completes our top five with a Best Score of 53. Its helical cutterhead houses 48 staggered carbide knives that align themselves without adjustment, and it planes boards up to 15 in wide and 6 in thick.
JET's Precision Air Strut System applies consistent upward pressure on the cutterhead to reduce snipe, a common problem on smaller planers. A precision-ground cast iron table and four-post design add stability and durability.
Dual infeed speeds of 16 fpm or 20 fpm let you balance speed and finish. Its cutterhead speed is listed at 5200 RPM, the lowest on this page. It is a larger, heavier machine than true benchtop planers, often used on a stand. For woodworkers who want carbide inserts and better snipe control in a 15 in width, it is a strong middle option. Connect it to a dust collector rather than a small shop vac to keep chips clear of the feed rollers.
VerdictA strong mid-size helical planer with snipe control.
Shop Fox W1865 with 92 inserts
Fourth with a Best Score of 57, the Shop Fox W1865 is a large stationary planer rather than a benchtop tool. Its helical cutterhead holds 92 inserts, the most on this page, and it planes 20 in wide and 8 in thick.
A 5 Hp motor drives the cutterhead through a triple v-belt drive. 2-speed chain-driven automatic feed rollers let you choose a faster feed for stock removal or a slower one for a better finish. Hardened anti-kickback fingers add safety, and a precision-ground cast-iron table with extension wings supports long boards.
At 909 lb it is the heaviest machine here by far, and it needs a permanent location and proper power. It has a dust port, which should be connected to a capable collector. For production shops and serious hobbyists with space, it offers the highest insert count and capacity on this page.
VerdictThe heavyweight option for production planing.
JET 13 in benchtop helical planer
The JET 722130 ranks third with a Best Score of 60. It is a true benchtop planer with a helical-style cutterhead using quick-change high-speed steel inserts for a smoother, quieter cut than straight knives.
A powerful 2-HP, 15-amp motor, listed at 1491 W, turns the cutterhead at 10,000 RPM. A precision-machined cast iron bed and steel cover help keep boards flat and reduce snipe, and a four-post design supports the cutterhead firmly.
It planes boards 13 in wide and 6 in thick and has a dust port. It carries a 3-year warranty, the longest listed on this page. High-speed steel inserts are cheaper to replace than carbide but wear faster in hardwood. For woodworkers who want a well-known brand in a benchtop helical planer, it is a strong pick. Keep a spare set of inserts on hand, since rotating or swapping them takes only minutes and keeps the finish clean.
VerdictThe best brand-name benchtop helical planer here.
Best among the reviewed tools
Helical heads use many small inserts set at an angle. They shear the wood, reducing tear-out in figured grain, run quieter and let you rotate a dull insert instead of replacing a full knife.
Carbide inserts last much longer in hardwood. High speed steel inserts are cheaper but dull sooner. Insert counts here range from 24 to 92.
Benchtop planers handle 13 in boards on 120V power. Stationary planers handle 15 to 20 in boards but weigh hundreds of pounds and may need 230V.
Cast iron beds, four-post heads and air strut systems reduce snipe. Supporting long boards on both ends helps too.
If you plane figured, curly or reclaimed wood, yes. Helical heads reduce tear-out and noise, and inserts are cheaper to maintain than full knives.
Carbide inserts last many times longer than steel knives, and each has several edges you can rotate to before replacing.
Aftermarket helical heads exist for some popular planers, but buying a planer with one built in is simpler.
The FindBuyTool MB320 leads our score among benchtop models, and the JET 722130 is the top brand-name benchtop option.
