Sheartak Spiral Cutterhead for Elektra Beckum HC 260 M Planer Thicknesser (Metabo)
Includes a full set of carbide inserts preinstalled.
Upgrade your Elektra Beckum or Metabo HC 260 M planer with the Sheartak spiral cutterhead and experience a dramatic improvement in performance, finish, and convenience. Many woodworkers retrofit their older planers and jointers with this system for the following advantages:
Key Benefits
-
Glassy Smooth Finish — No Tear-Out:
Each insert is set at a slight angle to create a true shear cut. The staggered spiral pattern eliminates tear-out and delivers a glossy surface even on highly figured hardwoods.
-
Significantly Quieter Operation:
Only a few knives engage the wood at a time, dramatically reducing noise compared with traditional straight-blade cutterheads.
-
Exceptional Durability:
The 15 × 15 × 2.5 mm sintered tungsten-carbide inserts last over 10 times longer than HSS knives. Each insert has four sharp edges that can be rotated as needed.
-
Fast, Easy Maintenance:
Precision-ground inserts (±0.0004″ / ±0.01 mm tolerance) are fully interchangeable. Simply loosen the screw, rotate 90°, and retighten to reveal a new edge in minutes.
-
Improved Dust Collection:
The spiral shear cut produces shorter, lighter chips for easier extraction and cleaner operation.
-
Cost-Effective Over Time:
No sharpening required and less sanding needed—your investment pays for itself quickly.
Standard Kit Includes
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.
