Spiral Cutterhead for Carbatec Deluxe 6" Jointer JN-150C with 30 Carbide Blades

Woodworkers around the world are upgrading their older planers and jointers with helical cutterheads to achieve superior performance and productivity. Key advantages include:

Superior Finish with Virtually No Tear-Out
Each carbide insert is mounted at a slight angle to create a shear-cutting action. Combined with the staggered arrangement of the inserts, the cutterhead produces a smoother, cleaner finish than traditional straight knives. Even highly figured hardwoods can be machined with minimal tear-out and an exceptionally smooth surface.

Significantly Reduced Noise Levels
Unlike conventional straight-knife cutterheads that strike the entire width of the workpiece at once, helical cutterheads engage the wood progressively. This staggered cutting action dramatically reduces operating noise.

Long-Lasting Carbide Inserts
The 15 × 15 × 2.5 mm inserts are manufactured from premium sintered tungsten carbide, providing more than ten times the service life of standard high-speed steel knives. Each insert features four precision-ground cutting edges, maximizing value and tool life.

Quick and Easy Knife Changes
Precision-ground to a tolerance of ±0.0004" (±0.01 mm), the inserts are fully interchangeable and require no knife-setting adjustments. Simply loosen the screw, rotate the insert 90° to expose a fresh cutting edge, and retighten. Most insert changes can be completed in minutes, minimizing downtime.

Improved Dust Collection Efficiency
The helical cutting action produces smaller, thinner wood chips that are easier for dust collection systems to capture, helping keep the machine and work area cleaner.

Lower Operating Costs
With no knife sharpening required and significantly reduced sanding time, a helical cutterhead can quickly pay for itself through lower maintenance costs, improved productivity, and superior finished results.

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.
