Spiral Cutterhead for WOODMASTER 18” Planer with 120 Carbide Knives
Upgrade the performance of your Woodmaster 18" Planer/Molder Model 718 with the Sheartak Helical Cutterhead. Equipped with 120 carbide inserts featuring curved edges, these inserts are strategically arranged along helical grooves at an angle, ensuring a true shear-cut. This upgrade will transform your planer, providing smoother cuts and superior results while reducing tear-out more effectively than traditional straight-knife cutterheads or other helical and spiral alternatives.
The Sheartak helical cutterhead delivers an exceptional finish, even on highly figured, challenging wood. Its indexable carbide inserts are more resistant to nicks and cracks compared to standard HSS knives. If an insert becomes dull or damaged, simply rotate it to expose a fresh, sharp edge—no need for time-consuming blade removal or sharpening. When all edges on an insert are worn out, replacing them is quick and easy with just a few turns of a Torx wrench, significantly reducing downtime.
Unlike traditional straight knives that make full contact with the material during every rotation, increasing shop noise, the staggered carbide inserts of the Sheartak helical cutterhead ensure that only one or two inserts contact the wood at any given time. This results in quieter operation and a more pleasant working environment.
The Sheartak helical cutterhead fits your original shafts perfectly, and installation is straightforward. Plus, it comes with a one-year warranty from the date of purchase.
Upgrade now and experience the difference!

Just installed on my woodmaster and all I can say is WOW, what a huge upgrade from the straight blade cutter head.\r\nSo much quieter and the finish is extremely smooth. Wish I had upgrade years ago

After using the spiral cutters extensively over the past month or so, I can say I am completely satisfied with their performance. Installation was straight forward without any tweaking or modifications required to the machines. The cutter on the Woodmaster planer cuts a beautiful surface that needs no sanding. It is much quieter than the straight blades. I used a sound meter to record about 12 db\'s difference in the sound level. Tear out on burls and knots is almost non-existent. The finished surface that the cutter produces is very flat. From the sound of the machine when cutting a full-width board, it does not appear to be working as hard to make the cut with the Sheartak cutter. All in all, I am very pleased with the cutter.

I installed the Woodmaster head(takes only 5 minutes). It works great. The tapered shafts went in easily, and tightened properly.
I decided to run some 2x4 cutoffs for my first test pieces. If I were you, that's what I would recommend to people. It's soft pine and full of hard knots. The grain direction switches back and forth. It is the perfect piece of cheap terrible milling wood to test a planer.
The results were very good. The knots cut cleanly, no chipping with grain direction. Scalloping was reasonable. The Woodmaster has a variable 0-32 ft/min feed motor. So I can slow it down a little bit to get a better cut. The cool thing is the amount of material removed doesn't seem to make a difference, which is really great. Meaning at a slow feed rate I can take 1/32 or 1/8 off in one pass with no difference in cut quality. I wasn't expecting that. As expected the head drops the noise level massively. No cut lines, so the teeth are all machined/installed properly.

I was very pleased with the finish to say the least. Glass smooth with no lines.
As I worked the stock previously you would learn which direction to feed it that produced the least tear out. With this head, it seemed it did not matter.

Do I need to replace the original bearings? If the bearings in your machine are in good condition, they can be reused by carefully removing them with a bearing or pulley puller. However, if the bearings are tightly pressed onto the shaft, removal may cause damage. To minimize this risk, we recommend replacing old bearings with our greased and sealed bearings, designed for long-lasting performance. For a smooth upgrade, we suggest adding the bearings to your shopping cart before completing your purchase. We provide premium bearings from NSK, SKF, NTN, FAG, Timken. They are renowned for their high quality and performance, designed to provide durability and reliability in various applications If you add the bearings to your order, we will preinstall them for you when premounting is possible, saving you the hassle of doing it yourself.
Do I need to to Add a Few Boxes of Carbide Inserts We provide 5 carbide inserts and 5 screws as spare parts. However, many of our customers choose to purchase additional boxes, as the shipping costs for separate purchases can make it less economical.
Do I need a Torque Wrench? To securely lock the carbide inserts, we recommend applying a torque of 48 to 52 Pound-Inches (or 5.42 to 5.88 Newton-Meters). (Note: 1 Newton-Meter is equal to 8.851 Pound-Inches, and 1 Pound-Inch is approximately 0.113 Newton-Meters.) It is crucial not to apply excessive torque, as this could cause the carbide inserts to crack or explode. On the other hand, using too little torque may result in the inserts not being properly secured, which could lead to cracks, shattering, or uneven height on the cutter block, causing ridges or lines on the board. If one person is responsible for maintaining the machine, they can typically apply the same torque consistently without a torque wrench. However, when multiple people are involved in machine maintenance, ensuring uniform torque application can be challenging. For consistency and peace of mind, we recommend using a torque wrench.
What kind of steel the cutter block is made of? The cutter block is constructed using GB/T 40Cr, a structural alloy steel of the same caliber as ASTM grade 5140, AISI 5140, SAE 5140, DIN 41Cr4, BS 41Cr4, JIS SCr440, and EN 41Cr4.The primary components of this steel are as follows: carbon (C) at a range of 0.37-0.44%, silicon (Si) between 0.17-0.37%, manganese (Mn) within 0.50-0.80%, and chromium (Cr) from 0.80-1.10%. In terms of physical properties, this steel exhibits a tensile strength range of 115-234σb/MPa, a yield strength of 2σ 0.2 ≥/MPa, and an elongation capacity of 65 δ5≥ (%). It also has a HBS range of 123-321 and a HRC rating of 30. This alloy steel is frequently utilized in low to moderately stressed components for machines, engines, and vehicles.
