The Porter Cable 126 Planer was a highly sought-after tool for door makers due to its spiral carbide blade. However, the blade is welded onto the cutterblock and requires helical sharpening. The lifespan of welded carbide is often reduced by up to 1/3 and after a few rounds of resharpening, it cannot be used any longer, making it difficult to find replacement cutterheads, even secondhand ones.
Fortunately, the Sheartak helical Cutter head provides an excellent solution to upgrading Porter Cable 126 Planer. It comes equipped with 14 indexable carbide inserts The staggered cutting design of the carbide inserts reduces tear-out noise during operation.
Each insert has four cutting edges. When an edge becomes dull or chipped, simply loosen, clean and turn it 90 degrees to expose a new sharp edge, and tighten it up. This process takes only minutes and eliminates the need for frequent replacements. The inexpensive carbide inserts are standard sizes and easily accessible, and their quality cut reduces sanding work by up to three-quarters. Additionally, the life span of carbide inserts is 50 times that of high-speed steel blades. The spiral cutter head also requires less power than a cutter head with HSS blades, making retrofitting much more cost-effective.
Key Features:
• Cutterhead material: Alloy steel
• Number of spirals: 2
• Number of carbide inserts: 14
• Insert size: 12x12x2.2mm
• Screw size: T15 M5

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.
