Value Collection 210-5502 Shell Mill Holder Straight Shank

Product Description

The VALUE COLLECTION 210-5502 is a straight-shank shell mill holder designed to mount shell mills and face mills onto manual or CNC milling machines. The holder accepts a 0.75-inch pilot diameter and features a 0.5-inch shank diameter, making it compatible with standard spindle configurations commonly found in knee mills and vertical machining centers. With an overall length of approximately 4.44 inches, this holder provides rigid tool support for face milling operations. No through-coolant port is present, so external coolant delivery is required when cutting fluid is needed. Machinists and toolroom technicians are the primary users of this style of arbor.

This shell mill holder is suited for light-duty to medium-duty face milling setups in job shops, maintenance departments, and production toolrooms. It accepts standard shell mills with a 0.75-inch pilot bore, which is a common size across many indexable and HSS shell mill offerings. The straight shank design allows direct mounting in collet chucks or end mill holders with a matching 0.5-inch bore. It is appropriate for both ferrous and non-ferrous milling applications where a compact, direct-mount arbor is preferred over taper-shank configurations.

Key Features

• 0.75-inch pilot diameter accepts standard shell mill bores
• 0.5-inch straight shank for direct mounting in compatible collet or end mill holders
• Overall length of 4.37 inches provides stable tool reach without excessive overhang

Compatibility

Designed as an OEM-style replacement or standard tooling option for milling setups requiring a 0.75-inch pilot shell mill holder with a 0.5-inch straight shank.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before mounting or removing the holder. Verify that the collet or end mill holder bore is clean and free of chips or burrs before inserting the straight shank to ensure full seating and minimize runout. Torque all retention fasteners to the machine or toolholder specification provided by the machine manufacturer.
