Sherline End Mill Holder Instructions
Ensures stability with single set screw
Supports longer and double-ended end mills
Enhances milling versatility with quick changes
Maintains CNC tool length consistency
Minimizes runout with tight tolerance threading
The Sherline End Mill Holder Instructions provide guidance on using an end mill holder that securely attaches to the threaded end of a mill spindle. This holder ensures that end mills are firmly held in place with a single set screw, preventing any spinning during heavy cuts, which can occur with collets. The design offers more support for the end mill compared to a collet, enhancing stability and performance.
The holder is compatible with longer or double-ended end mills and is available for various sizes of cutting tools. It is particularly suitable for special purpose cutters with 3/8-inch diameter shanks, such as those used for cutting key slots, dovetails, and corner radii. This versatility increases the functionality of a milling machine, allowing for quick changes between cutters by simply unscrewing one holder and threading on another.
In CNC operations, the use of multiple pre-mounted holders with their own end mills ensures that tool length remains consistent, eliminating the need to update tool diameter and length values in the CNC program's tools table.
Note: The thread pitch diameter on both the end mill holder and the headstock spindle is held to a tight tolerance to minimize runout. It is recommended to apply a drop of light oil on the threads before threading the holder onto the spindle, as some holders may fit tightly initially.
