Value Collection 375-1206 Carbide Tipped Boring Bar Set 9 Pc

Product Description

The VALUE COLLECTION 375-1206 is a 9-piece carbide-tipped boring bar set designed for internal diameter boring on lathes and turning centers. Each bar in the set features a C6 carbide-tipped insert with a bright, uncoated finish and a right-hand cutting direction. The set spans from the smallest bar at 5/16 inch minimum bore diameter and 2-1/4 inch overall length up to the largest bar at 9/16 inch minimum bore diameter and 4-1/2 inch overall length. All bars share a 1/2 inch shank diameter. The set ships in a wood storage stand. Machinists and tool-and-die professionals reach for this set when boring small-diameter blind or through holes to precise tolerances.

This boring bar set is suited for light to medium-duty internal boring operations on manual lathes and CNC turning centers in job shops, maintenance machining environments, and production settings. Maximum bore depth ranges from 3/4 inch on the smallest bar to 3 inches on the largest bar, giving the user a range of reach for varying workpiece depths. The right-hand cut orientation is standard for conventional lathe spindle rotation.

Key Features

• C6 carbide-tipped construction for wear resistance and longer edge life compared to high-speed steel
• 9-piece set covers minimum bore diameters from 5/16 inch to 9/16 inch in a single purchase
• 1/2 inch uniform shank diameter across all bars for consistent tool-holder setup
• Maximum bore depth up to 3 inches on the largest bar in the set
• Right-hand cut direction compatible with standard lathe spindle rotation
• Wood storage stand included for organized bench storage and tool protection

Compatibility

Designed for use with standard 1/2 inch boring bar tool holders on manual and CNC lathes and turning centers. Verify tool-holder bore size and minimum bore diameter clearance before mounting.

Installation Notes

Installation is performed by a machinist or qualified shop technician. Before mounting, power down and lock out the lathe or turning center per machine-specific lockout/tagout procedures. Seat the shank fully in the tool holder and tighten set screws to the tool-holder manufacturer specification. Confirm the bar extends only as far as required for the bore depth to minimize overhang and reduce chatter risk.
