Value Collection 230-7210 R8 Collet Chuck Set 1in 5pc

Product Description

The VALUE COLLECTION 230-7210 is an R8 taper shank full grip collet chuck set designed for use in manual milling machines equipped with an R8 spindle taper. Built around the 1 inch collet series, this set provides secure, full grip clamping on cutting tools and toolholders to minimize runout and maintain concentricity under load. Weighing 10.18 pounds, the set is substantial enough for production use on Bridgeport-style and similar knee mills. Machinists and tool and die technicians rely on full grip collet systems for positive tool retention during face milling, end milling, and drilling operations.

This set is suited for manual vertical milling machines in job shops, maintenance facilities, and light production environments where an R8 spindle interface is standard. The full grip collet design distributes clamping force evenly around the tool shank, reducing the risk of slippage during interrupted cuts or high-feed passes. The 1 inch series collets accommodate a range of shank diameters within that series, making the set versatile across common tooling inventories. Five collets are included, covering multiple shank sizes in a single purchase.

Key Features

• R8 taper shank interfaces directly with R8 spindle machines without an adapter
• Full grip collet design provides uniform clamping force and reduced runout
• 1 inch collet series covers a practical range of cutting tool shank sizes
• Set of 5 collets included for multi-diameter tooling coverage
• UNSPSC Code 27112808 for procurement and catalog classification

Compatibility

Designed as an OEM-style replacement and aftermarket fit for manual vertical milling machines with an R8 spindle taper, consistent with Bridgeport-style knee mill configurations.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the machine spindle fully stopped and the power isolated at the machine disconnect. The R8 collet and drawbar threads should be inspected for damage before each use, and the collet taper and spindle bore should be clean and free of chips or coolant residue before seating the collet. Drawbar torque should follow the machine manufacturer specifications. Do not use a collet outside its rated shank diameter range, as over-tightening an improperly sized collet can damage both the collet and the spindle bore.
