Value Collection 383-1146 Single-point Tool Bit BL-7

Product Description

The VALUE COLLECTION 383-1146 is a left-hand single-point tool bit built to industry standard BL-7 for lead angle turning operations. It features a solid carbide tip rated C6, a 7/16 inch shank height, and a 7/16 inch shank width. The overall length is 3 inches. The C6 carbide grade provides the hardness and wear resistance needed for interrupted cuts, boring, chamfering, and general turning on a lathe. Machinists and tool-and-die professionals working in production or maintenance environments use this style of bit for reliable, repeatable material removal on steel, cast iron, and similar workpiece materials.

This tool bit is suited for manual and CNC lathes requiring a left-hand cutting direction. The 15-degree lead angle geometry is appropriate for standard turning passes, shoulder work, chamfering, and boring applications. Its compact 3-inch overall length fits common tool holders designed for BL-series bits. At 0.12 pounds, the bit is lightweight and easy to index without upsetting tool-post balance. It is packaged individually and is a practical single-piece replacement or stock addition for machine shops and maintenance facilities.

Installation Notes

Installation is performed by a machinist or qualified tool-room technician. Power down and lock out the lathe before seating or adjusting the tool bit in the holder. Ensure the shank is fully seated and the set screw is tightened securely before resuming operation. Inspect the carbide tip for chipping or wear before each use, as a damaged tip can affect surface finish and dimensional accuracy.
