Value Collection 375-1607 Boring Bar Set 14 Piece M35 Cobalt

Product Description

The VALUE COLLECTION 375-1607 is a 14-piece boring bar set machined from M35 high-speed steel cobalt material with an uncoated bright finish. The set covers a minimum bore diameter range of 3/8 inch on the smallest bar up to 3/4 inch on the largest bar. Maximum bore depth spans from 1-1/8 inches on the smallest bar to 3-3/4 inches on the largest. All bars feature a 3/4-inch shank diameter and an overall length range of 2-7/8 to 5-1/2 inches. Right-hand cutting geometry is standard across the set. A wooden stand is included for organized storage and quick access at the machine. This set is intended for use by machinists in production, toolroom, and job-shop environments.

This boring bar set is suited for internal diameter turning operations on manual lathes and CNC turning centers where close-tolerance bore work is required. The range of bar sizes makes the set practical for small-bore applications across a variety of workpiece materials. The M35 cobalt construction provides hardness and heat resistance appropriate for steel, cast iron, and other ferrous workpieces. The set is commonly used by machinists performing repair, prototype, and production turning work.

Compatibility

Designed for use in toolholders and boring bar holders accepting a 3/4-inch shank diameter on manual and CNC lathes. No specific machine model compatibility was provided in product data.

Installation Notes

Installation should be performed by a qualified machinist following established shop safety procedures. Secure each bar firmly in the toolholder to the manufacturer-specified clamping method before operation. Ensure the lathe spindle is fully stopped and locked out before changing or adjusting boring bars. Verify shank diameter compatibility with the toolholder before mounting any bar from the set.
