Value Collection 375-1836 Boring Bar C6 Carbide-tipped

Product Description

The VALUE COLLECTION 375-1836 is a right-hand boring bar designed for internal turning and bore enlargement operations on a lathe. The cutting tip is C6 carbide-tipped, a grade suited for general-purpose machining of cast iron, steel, and non-ferrous materials at moderate to high cutting speeds. The bar accepts a minimum bore diameter of 0.875 inches and reaches a maximum bore depth of 4.5 inches, making it practical for a wide range of through-hole and blind-hole boring jobs. The 1-inch shank diameter seats securely in standard boring bar holders, and the 6.5-inch overall length provides reach without excessive overhang. Machinists and toolroom technicians are the primary users of this tool.

This boring bar is suited for job shop and production environments where consistent internal diameter finishing is required. It works in manual engine lathes and turret lathes where a 1-inch shank tool holder is available. Typical applications include bore sizing, cleanup passes after rough drilling, and preparing bores to close tolerance for bearing or bushing fits. The right-hand cutting direction means the bar cuts when feeding from right to left, consistent with standard lathe operation.

Key Features

• C6 carbide-tipped insert for general-purpose cutting performance on steel and cast iron
• Minimum bore diameter of 0.875 inches allows entry into tight bore openings
• Maximum bore depth of 4.5 inches provides reach for deep internal passes
• 1-inch shank diameter fits standard boring bar holders on most engine and turret lathes
• Right-hand cutting direction for conventional lathe feed operation
• 6.5-inch overall length balances reach and rigidity

Compatibility

Designed for use in standard lathe tool posts and boring bar holders that accept a 1-inch round shank. Confirm holder clearance and minimum bore diameter requirements before installation.

Installation Notes

Installation should be performed by a qualified machinist. Power down and lock out the lathe before mounting or adjusting the boring bar in the tool holder. Ensure the bar is clamped securely with minimal overhang beyond the holder to reduce chatter and deflection. Verify workpiece fixturing and spindle speed before taking a cutting pass.
