Value Collection 220-1570 Boring Head Straight Shank

Product Description

The VALUE COLLECTION 220-1570 is a straight-shank boring head designed for use on milling machines and boring mills where a threaded mount interface is required. The shank measures 3/4 inch in diameter and uses a 1-1/2-18 threaded mount to secure the head to compatible tooling systems. Weighing 0.5 pounds, this compact unit suits light-to-medium material removal operations. Coolant-through capability is not present on this model, making it best suited for dry or flood-coolant external applications. Machinists and toolroom technicians use this type of boring head to achieve precise bore diameters in a range of workpiece materials.

This boring head is appropriate for use in job shop, production, and maintenance machining environments where straight-shank toolholding is the standard setup. The 1-1/2-18 threaded mount provides a secure, repeatable connection to compatible boring bars and arbors. It is well suited for operations requiring tight bore tolerances in ferrous and non-ferrous materials on knee mills, bed mills, and horizontal boring machines. Installation and setup are performed by machinists familiar with threading tooling onto spindle-side adapters and dialing in offsets using a dial indicator.

Key Features

• 3/4 inch straight shank diameter for compatibility with standard straight-shank toolholders
• 1-1/2-18 threaded mount interface for secure tool connection
• Lightweight at 0.5 pounds for reduced spindle load
• No coolant-through porting — suitable for external flood or dry cutting setups
• Compact design suited for light-to-medium boring operations

Compatibility

Designed as a straight-shank, threaded-mount boring head for use with compatible 1-1/2-18 threaded boring bars and arbors on milling machines and boring mills that accept a 3/4 inch straight shank.

Installation Notes

Installation should be performed by a qualified machinist. Before mounting or adjusting the boring head, ensure the machine spindle is fully stopped and the machine is powered down or placed in an E-stop state. Thread the boring head onto the arbor or adapter by hand first to confirm proper thread engagement before applying a wrench. Use a dial test indicator to verify bore offset before taking a cut, and confirm all locking screws are secured to prevent offset shift during operation.
