Value Collection 210-5508 Shell Mill Holder 1 in Pilot

Product Description

The VALUE COLLECTION 210-5508 is a straight-shank shell mill holder designed to secure shell mills and face mills in CNC machining centers and manual milling machines. The holder features a 1-inch pilot diameter and a 3/4-inch straight shank, with an overall length of approximately 155.50 mm (6.12 inches). It provides a rigid, concentric interface between the machine spindle and the cutting tool, which is critical for maintaining accuracy and surface finish during face milling and contouring operations. This holder does not include through-coolant capability. Machinists and CNC operators in metalworking shops are the primary installers and users of this toolholder.

This shell mill holder is suited for use in job shops, production machining environments, and tool rooms where straight-shank tooling is required. It is compatible with milling machines and machining centers that accept a 3/4-inch straight shank. The 1-inch pilot diameter accommodates standard shell mills and face mills with a corresponding bore. Typical applications include flat surface milling, shoulder milling, and general-purpose material removal on ferrous and non-ferrous workpieces.

Key Features

Compatibility

Designed as an OEM-style replacement or direct-fit toolholder for milling machines and machining centers that accept a 3/4-inch straight shank and use shell mills with a 1-inch pilot bore.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator with the machine powered down and the spindle locked before mounting or removing the holder. The straight shank should be clean and free of burrs before insertion into the spindle or chuck. Torque any retention screws or drawbar fasteners to the machine tool manufacturer specifications — do not over-tighten. Verify runout with a dial indicator after installation before commencing any cutting operation.
