Spiral Cutter Head for SCM Minimax LAB30 Combo Machine
Complete Kit with Carbide Inserts
Upgrade your SCM Minimax LAB30 with a premium spiral cutter head designed to deliver superior performance, cleaner cuts, and longer tool life.
Key Benefits
Exceptional Surface Finish
Each carbide insert is set at a slight angle to create a true shear cut. Combined with the staggered cutting pattern, this design significantly reduces tear-out and produces an ultra-smooth, near-gloss finish—even on highly figured hardwoods.
Quieter Operation
The staggered cutting action means fewer knives engage the wood at once, resulting in a noticeable reduction in noise compared to traditional straight knife cutter heads.
Long-Lasting Carbide Inserts
Made from sintered tungsten carbide, the 15 × 15 × 2.5 mm inserts offer over 10× the lifespan of high-speed steel. Each insert features four usable edges for extended performance.
Quick & Easy Maintenance
Precision-ground inserts are fully interchangeable. Simply loosen the screw, rotate the insert 90° to a fresh edge, and retighten—no sharpening required.
Improved Dust Collection
Produces smaller, thinner chips that are easier to extract, helping keep your workspace cleaner and your dust collection system more efficient.
Cost-Effective Upgrade
Delivers a smoother finish straight off the machine, reducing or eliminating sanding time. With no sharpening required and long insert life, this cutter head quickly pays for itself.
Standard Kit Includes
-
High-tensile alloy steel cutter block

Perfect for woodworkers looking to enhance cut quality, reduce maintenance, and improve overall efficiency.
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.
