Sherline End Mill Holder 1/4″ - 1/4
Description
- Sherline End Mill Holder 1/4″ - 1/4
- Enhances milling with secure end mill holding
- Facilitates quick tool changes for CNC
- Supports longer and double-ended mills
- Optimizes tool diameter and length consistency
- Accommodates special-purpose cutters
The Sherline End Mill Holder 1/4″ - 1/4 is designed to enhance the functionality of milling machines by securely holding end mills in place. This holder screws onto the threaded end of the mill spindle and utilizes a single 10-32 set screw to ensure the end mill remains stationary during heavy cuts, providing more support compared to a collet. The design allows for the use of longer or double-ended end mills, increasing the versatility of the milling machine.
This end mill holder is particularly beneficial for CNC operations, as it facilitates a quick-change tool system. By keeping cutters mounted in their own holders, users can swiftly switch between tools without altering the tool length values in the CNC program. This feature is advantageous for maintaining consistent tool diameter and length values, streamlining the machining process.
The holder is compatible with various special-purpose cutters, such as those for key slots, dovetails, and corner radii, which typically have 3/8″ diameter shanks. This compatibility further extends the range of applications for which the milling machine can be used.
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 initial use, as some holders may fit tightly at first.
