Upgrade your Craftsman 13" Planer Model 351.217430, Model 351.217430, with a Sheartak spiral cutterhead and experience professional-grade results. Many woodworkers are now retrofitting their planers and jointers with spiral cutterheads because of the unmatched performance and durability they deliver.
Key Benefits:
-
Smoother Finish with No Tear-Out – Each carbide insert sits at a slight angle for a shear cut. Combined with the staggered spiral design, this reduces tear-out and leaves a glassy, smooth surface even on figured hardwood.
-
Quieter Operation – Only a few inserts cut at a time, greatly reducing noise compared to straight-knife cutterheads.
-
Longer Tool Life – The 15×15×2.5mm sintered tungsten carbide inserts last 10x longer than high-speed steel blades. Each insert has 4 sharp edges for easy rotation and extended use.
-
Simple Maintenance – Inserts are precision-ground to ±0.0004" (±0.01mm) tolerance. Just loosen the screw, rotate 90°, and tighten for a fresh edge in minutes.
-
Improved Dust Collection – Spiral design produces smaller, thinner chips that are easier to extract.
-
Cost-Effective – No more resharpening or constant blade changes. The cutterhead pays for itself quickly by reducing downtime, sanding, and replacement costs.
Bring new life to your Craftsman planer/molder with Sheartak’s spiral cutterhead—delivering smoother cuts, longer life, and a quieter, more efficient shop.
Kit includes:
- High tensile strength alloy steel cutterblock.
- 40 carbide inserts installed.
- 5 extra carbide inserts.
- 5 extra screws.
- 1 Torx head T type wrench.
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.
