Casadei PS 630 Thickness Planer – Precision and Power for Professional Workshops
The Casadei PS 630 is a heavy-duty industrial thickness planer, widely respected in professional woodworking shops for its rigid construction, powerful motor, and consistent thicknessing accuracy. Designed for high-volume use, the PS 630 delivers stable performance on hardwoods and demanding materials, making it a long-term investment for serious woodworkers. Many PS 630 machines are still mechanically sound after decades of service, making them ideal candidates for performance upgrades.
Upgrade Your Casadei PS 630 with a Sheartak Helical Cutterhead
Woodworkers are increasingly retrofitting older planers like the Casadei PS 630 with Sheartak helical (spiral) cutterheads to dramatically improve cutting quality, reduce noise, and lower long-term operating costs.
The Sheartak Helical Cutterhead for Casadei PS 630 is supplied with a full set of premium carbide inserts and is engineered as a direct performance upgrade over traditional straight-knife cutterheads.
Key Advantages of the Sheartak Helical Cutterhead
-
Smoother finish with virtually no tear-out
Each carbide insert is set at a slight shear angle, producing a staggered, shearing cut rather than a single straight impact. This design virtually eliminates tear-out and leaves a glossy surface finish, even on highly figured hardwoods.
-
Significantly reduced noise
The spiral layout allows multiple inserts to engage the workpiece gradually, resulting in much quieter operation compared to straight knives.
-
Over 10× longer cutting life than HSS knives
The 15 × 15 × 2.5 mm inserts are made from sintered tungsten carbide, far harder than high-speed steel. Each insert features four usable cutting edges, greatly extending service life.
-
Fast and easy blade changes
Inserts are precision-ground to a tolerance of ±0.0004" (±0.01 mm) and are fully interchangeable. Simply loosen the screw, rotate the insert 90° to a fresh edge, and retighten—no knife setting or alignment required.
-
Improved dust extraction
The spiral cutting action produces thinner, shorter chips that are easier for dust collection systems to capture.
-
Lower cost of ownership
With no sharpening required, reduced sanding time, and extended insert life, the helical cutterhead quickly pays for itself in daily shop use.

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.
