Transform your workshop with our expertly engineered Craftsman woodworking tools featuring advanced spiral cutterhead technology. Designed specifically for Craftsman planers and jointers, our collection delivers professional-grade performance that revolutionizes how you work with wood.
Each precision-crafted cutter head represents a significant upgrade over traditional straight-knife systems. Our helical design incorporates multiple carbide inserts arranged in a strategic spiral pattern, creating a superior shear-cutting action that eliminates tear-out even on the most challenging figured hardwoods and knotty softwoods.
These advanced mechanical components are precision-engineered to fit Craftsman machines perfectly, from 6" jointers to 15" planer molders. Whether you're retrofitting a classic Craftsman 152.217060 jointer or upgrading your 351.217430 planer, our spiral cutterhead jointer solutions deliver exceptional results with dramatically reduced noise levels and extended tool life.
The tungsten carbide inserts in these woodworking tools stay sharp up to 50 times longer than traditional high-speed steel blades. Each insert features four cutting edges that can be rotated in minutes when one edge dulls—no complex sharpening or blade setting required. This innovative design means less downtime and more productivity in your shop.
Manufactured with premium Japanese NSK bearings and backed by comprehensive warranty coverage, our Craftsman woodworking tools represent a smart investment that pays for itself through reduced maintenance costs, improved cut quality, and elimination of sanding work. Experience the difference that professional-grade spiral technology makes in your woodworking projects.
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
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.
