The spindle doesn't come with a collet, so if you don't have one, you'll have to purchase the ER11 collet holder separately. This spindle is best suited for engraving on soft materials and aluminum. Make sure your spindle and ER collet sizes are compatible. It is compatible with ER11 collets that can hold tools with 0.276" inches of shaft diameter.ĮR collets can be adjusted within a range. The diameter of this spindle is 1.7" and can be mounted using a clamp mount. The spindle weighs less than 1 lb, with a rigid body made of steel, and is air-cooled.

I have sorted them based on their power output, starting with low-power spindles and progressively moving up to a 4 kW spindle.ĭepending on their RPM and rigidity, some of these can be used for metal milling while others are suitable for softer materials.Īt the end of this article, I have talked about the factors to consider while selecting a spindle for your CNC. The factors I considered while compiling this list are the power output, the build quality of the spindle, collet size, and the cooling system. If you don't have the time or patience to manually change tools, you can choose an Automatic Tool Changer (ATC) spindle but they are expensive compared to regular spindles. The best CNC spindle for your application will depend upon the hardness of the materials you intend to process and the speed with which you need to get it done.
In this guide, I list the best CNC spindles available on the market in 2022. Maybe you're planning on upgrading your existing CNC spindle or you're building a new CNC router from scratch and you need a good spindle.
