The Sheartak Spiral Cutterhead for the Rockwell B1467 4" Jointer is equipped with a total of 18 carbide inserts on 5 spirals, with 5 extra inserts and screws provided as spare parts. Each carbide insert is designed to share the same amount of wood, and on the same cutting materials, the lifespan of the inserts on more-insert cutterheads is longer than on fewer-insert cutterheads. With 102 carbide inserts on 5 rows, this cutterhead is highly productive and cost-effective. For further information, contact us at our Toll-Free number 187741-SHEAR (18774174327). We have the Sheartak spiral cutterhead in stock and can ship it out from our Waterloo Ontario, Canada store on the next business day. Our cutterheads leave a superior surface finish over straight-edge cutterheads, thanks to the round-edged inserts that are angled for a shear-cut, which produces a glassy smooth cut, even on highly figured woods or very soft wood. Each insert features four cutting edges and can be rotated up to 3 times to reveal a fresh sharp edge, eliminating the need for sharpening and resetting when an insert gets dull or nicked. Carbide inserts stay sharp 50 times longer than HSS blades, and dust extraction is much easier with the shorter and thinner chips cut by Sheartak spiral cutterheads. All of our cutterheads come with a one-year warranty from the date of purchase, which covers parts and ensures that they are free from manufacturer defects. (Consumables are not covered.)

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.
