Sheartak Helical Cutterhead for Grizzly G1037 Planer/Molder with Full Set of Carbide Inserts
Upgrade your Grizzly G1037 Planer/Molder with a premium Sheartak helical cutterhead. Designed to deliver superior cutting performance, quieter operation, and longer service life, this cutterhead is supplied complete with a full set of premium carbide inserts.
Benefits of a Sheartak Helical Cutterhead
Superior Surface Finish
Each carbide insert is mounted at a slight angle to produce a true shear cut. The helical arrangement creates a staggered cutting action that significantly reduces tear-out and leaves an exceptionally smooth surface, even on highly figured hardwoods.
Quieter Operation
Unlike traditional straight-knife cutterheads that strike the entire width of the board at once, the helical design engages the wood gradually. This staggered cutting action substantially reduces noise levels during operation.
Extended Tool Life
The included 15 x 15 x 2.5 mm carbide inserts are manufactured from premium sintered tungsten carbide, offering more than ten times the service life of conventional high-speed steel knives. Each insert features four precision-ground cutting edges for maximum value and longevity.
Quick and Easy Maintenance
The inserts are precision ground to a tolerance of ±0.01 mm (±0.0004") and are fully interchangeable. When an edge becomes dull, simply loosen the screw, rotate the insert 90 degrees to a fresh cutting edge, and retighten.
Improved Chip Removal
The helical cutting action produces smaller, thinner chips, helping improve dust collection efficiency and reducing the likelihood of chip buildup.
Lower Operating Costs
With no knife sharpening required, reduced sanding time, and four cutting edges per insert, a Sheartak helical cutterhead quickly pays for itself through increased productivity and lower maintenance costs.
Package Includes
Upgrade your machine with the cutting performance, finish quality, and reliability trusted by professional woodworkers worldwide.
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.
