Value Collection 220-1575 Boring Head Straight Shank

Product Description

The VALUE COLLECTION 220-1575 is a straight-shank boring head designed for precision metal-removal operations on mills and boring machines. It mounts via a 7/8-20 threaded interface and features a 1-inch shank diameter, making it a practical tooling choice for machinists and tool-and-die professionals setting up boring operations. The straight shank profile is compatible with standard collet chucks and toolholders that accept a 1-inch round shank. Coolant-through capability is not available on this unit. At 1 pound, the head is manageable for manual setup and tool-change workflows on benchtop and knee-mill platforms.

This boring head is suited for light to medium boring operations in job-shop, maintenance machining, and production environments. Typical applications include enlarging or finishing existing holes to precise diameters in ferrous and non-ferrous workpieces. The 7/8-20 threaded mount allows the boring head body to accept compatible boring bars and inserts that match that thread standard, giving the technician flexibility in setting bore diameter across a range of cuts.

Compatibility

Designed as a standard replacement or supplemental boring head for milling machines and boring setups that use a 1-inch straight shank toolholder and accept a 7/8-20 threaded boring bar interface.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is powered down before inserting or removing the shank from the toolholder. Secure the shank firmly in the collet or chuck to the toolholder manufacturer's recommended clamping procedure before initiating a cut. Verify boring bar thread engagement is complete and the bar is properly seated before taking any material pass.
