Value Collection 210-0402 Shell Mill Holder R8 Taper Shank

Product Description

The VALUE COLLECTION 210-0402 is an R8 taper shank shell mill holder designed for use on vertical milling machines equipped with an R8 spindle. It accepts shell mill cutters with a cutting diameter range of 1-3/4 to 2 inches and features a 3/4 inch pilot diameter for secure, centered cutter engagement. The overall length is 154 millimeters, providing standard reach for most knee mill and bed mill applications. This holder is a solid, no-frills toolholding component suited to machine shops, toolrooms, and maintenance facilities where R8 spindle tooling is standard. No through-coolant port is included in this design.

This shell mill holder is intended for use on Bridgeport-style knee mills and other manual or CNC vertical mills with R8 spindle interfaces. It is suited to face milling, shoulder milling, and surface stock-removal operations using shell mill cutters in the 1-3/4 to 2 inch diameter range. Machinists and toolroom operators in job shops, maintenance departments, and production facilities will find this holder a practical fit for general-purpose milling work where R8 tooling is already in use.

Key Features

• R8 taper shank interfaces directly with standard R8 spindle mills without adapters
• Pilot diameter of 3/4 inch provides positive cutter location and concentricity
• Compatible with shell mill cutters in the 1-3/4 to 2 inch cutting diameter range
• 154 millimeter overall length suits standard knee mill and bed mill clearance requirements
• No through-coolant path keeps the design simple and compatible with dry or flood coolant setups applied externally

Compatibility

Designed as an OEM-style replacement or standard toolholding component for vertical milling machines equipped with an R8 spindle, accepting shell mill cutters in the 1-3/4 to 2 inch cutting diameter range with a 3/4 inch pilot bore.

Installation Notes

Installation is performed by a machinist or toolroom technician. The machine spindle must be powered down and brought to a full stop before inserting or removing the holder. The R8 shank is secured using the machine drawbar; tighten the drawbar to the mill manufacturer specification using the appropriate wrench. Inspect the shank and spindle bore for chips or burrs before seating the holder to ensure full taper contact and safe cutter engagement.
