Transform your trusty Sears Craftsman 6 1/8" Inch Jointer Planer Model No. 113.20651 into an advanced machine by upgrading it with a Sheartak Helical cutterhead.
Your Craftsman 103.20651 6" Jointer may have been with you for years, but it can still perform like a brand new machine with the addition of a Sheartak spiral cutterhead. With 30 carbide inserts on 5 spirals, each with 4 indexable edges, the Sheartak cutterhead is designed with a slight angle to the board feeding, which produces a shear cut that eliminates tear-out and leaves a glossy surface finish on softwood, hardwood, and man-made board. This also significantly reduces operational noise.
When a carbide insert becomes dull or chipped, simply rotate the edge 90 degrees to expose a new sharp edge. The inexpensive carbide inserts only need to be discarded when all four edges are affected, eliminating the need to sharpen them and greatly reducing downtime. Sheartak spiral cutterheads also remove short chips in a staggered way, reducing three-quarters of your sanding work and consuming less power. They also avoid dust clogging at the hood port, significantly improving dust extraction.
Investing in a Sheartak spiral cutterhead can pay for itself in no time and take your Sears Craftsman Jointer to the next level.
Craftsman 103.20651 6" Jointer Kit includes:
* High tensile strength alloy steel cutter block.
* 30 carbide inserts installed.
* 5 extra carbide inserts.
* 5 extra screws.
* 2 set crews.
* 1-year warranty for cutter block.
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.
