Upgrade Your Griggio LM 410A with Sheartak's Spiral Cutterhead
Transform your woodworking experience with Sheartak's Spiral Cutterhead, designed specifically for the Griggio LM 410A Combined Machine featuring 102 carbide inserts for superior cutting efficiency. This high-performance upgrade offers superior finish quality, reduced noise levels, and increased durability. Each unit includes 5 extra inserts and 5 spare screws, and is backed by a 1-year warranty on the cutterblock from the purchase date.
Key Features:
-
Staggered Cutting Action: Each of the 102 carbide inserts is positioned at a slight angle, creating a staggered cutting action that eliminates tear-out and delivers a smooth finish on all types of boards.
-
Reduced Noise Levels: The spiral design ensures that each cutter removes material in short, gradual increments, significantly reducing noise during operation.
-
Durable Carbide Inserts: The 15x15x2.5mm sintered tungsten carbide inserts offer greater durability and performance compared to high-speed steel. Each insert features four cutting edges for extended use.
-
Easy Maintenance: The precision-ground carbide cutterheads are fully interchangeable. Simply loosen the screw, rotate the insert 90° to access a new edge, and retighten the screw—changing inserts takes only minutes.
-
Enhanced Dust Collection: The spiral design minimizes the risk of chip clogging in the dust extraction system, ensuring efficient dust collection.
-
Cost-Effective Operation: The spiral cutterheads reduce the need for sanding by up to 75% and never require sharpening, offering long-term savings and a quick return on investment.
Included in the Kit:
- High tensile strength alloy steel cutter block
- 102 carbide inserts pre-installed
- 5 extra carbide inserts
- 5 extra screws
- 1 Wrench
Upgrade your Griggio LM 410A Combined Machine with Sheartak's Spiral Cutterhead and experience enhanced performance, quieter operation, and reduced maintenance.
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.
