Value Collection 375-1202 Boring Bar Set 9 Piece C2 Carbide

Product Description

The VALUE COLLECTION 375-1202 is a 9-piece carbide-tipped boring bar set designed for internal boring operations on a lathe or boring machine. Each bar in the set features a C2 grade carbide tip, a bright uncoated finish, and a right-hand cutting direction. The set spans a range of bar sizes, with minimum bore diameters from 5/16 inch on the smallest bar up to 9/16 inch on the largest, and overall lengths from 2-1/4 inches to 4-1/2 inches. A consistent 1/2-inch shank diameter across all bars allows the set to seat in a standard tool post or boring head without re-adjusting the holder for each bar swap. The complete set weighs 2.37 pounds and stores in a fitted wood stand.

This set is suited for machinists and toolroom operators working on small to medium internal bore diameters in ferrous and non-ferrous materials. Typical applications include finish boring of through-holes and blind bores on manual engine lathes and turret lathes. The range of bar sizes makes this set practical for shops that need flexibility across multiple bore diameters without maintaining individual bars in separate tool storage. Maximum bore depth reaches 3/4 inch on the smallest bar and 3 inches on the largest bar in the set.

Key Features

• C2 carbide-tipped cutting edges for wear resistance across a range of workpiece materials
• Right-hand cutting direction compatible with standard lathe rotation
• Minimum bore diameter range: 5/16 inch (smallest bar) to 9/16 inch (largest bar)
• Maximum bore depth range: 3/4 inch (smallest bar) to 3 inches (largest bar)
• Consistent 1/2-inch shank diameter across all 9 bars for single tool-holder setup
• Fitted wood stand included for organized storage and quick bar selection

Compatibility

Designed for use with standard 1/2-inch shank tool posts, boring heads, and turret lathe holders that accept a 1/2-inch round shank boring bar.

Installation Notes

Installation is performed by qualified machinists familiar with lathe tooling setup. Power down and lock out the machine before changing or seating any boring bar in the tool holder. Verify that the bar shank is fully supported in the holder and that the carbide tip is oriented correctly for right-hand cutting before resuming operation. Avoid extending bars beyond the recommended maximum bore depth to prevent chatter and tool deflection.
