Sheartak Helical Cutterhead for Bosch GHO 700 Portable Planer with 14 Carbide Inserts
Upgrade your Bosch GHO 700 Portable Planer with a premium Sheartak Helical Cutterhead engineered for superior cutting performance, longer tool life, and a noticeably quieter woodworking experience.
Woodworkers around the world are replacing traditional straight-knife cutterheads with helical cutterheads for the following benefits:
Superior Surface Finish
Each carbide insert is mounted at a slight angle to create a true shear-cutting action. Unlike conventional straight knives that strike the full width of the board at once, the helical cutterhead cuts in a staggered pattern. This combination of shear and staggered cutting dramatically reduces tear-out and leaves an exceptionally smooth surface, even on highly figured hardwoods.
Significantly Reduced Noise
The staggered cutting action allows only a few inserts to engage the wood at any given time, resulting in noticeably quieter operation compared to conventional straight-knife cutterheads.
Extended Cutting Life
The cutterhead is equipped with 14 premium tungsten carbide inserts. Carbide is substantially harder and more wear-resistant than high-speed steel (HSS), providing up to 10 times longer cutting life under normal woodworking conditions.
Four Cutting Edges Per Insert
Each insert features four precision-ground cutting edges. When an edge becomes dull, simply loosen the screw, rotate the insert 90 degrees to a fresh edge, and retighten. No knife setting or sharpening is required.
Easy Maintenance
All inserts are manufactured to a precision tolerance of and are fully interchangeable, making maintenance quick and hassle-free.
Improved Chip Removal
The helical cutting action produces smaller, thinner chips that are easier for dust collection systems to handle, helping keep your workshop cleaner.
Lower Operating Costs
With longer-lasting carbide inserts, no sharpening expenses, reduced sanding requirements, and improved surface quality, a Sheartak Helical Cutterhead quickly pays for itself while enhancing the performance of your planer.

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.
