Value Collection 383-1172 Single-point Tool Bit BL-12

Product Description

The VALUE COLLECTION 383-1172 is a BL-style single-point tool bit designed for lead angle turning operations on metalworking lathes. It features a C2-grade solid carbide tip brazed to a steel shank, delivering the hardness and wear resistance required for general-purpose turning, boring, chamfering, and interrupted-cut applications. The shank measures 3/4 inches in height and 3/4 inches in width, with an overall length of 4.5 inches. The 15-degree lead angle geometry and left-hand cutting direction make this bit suited for operations where the tool feeds from left to right across the workpiece. Machinists and tool-and-die professionals are the primary installers of this type of tooling.

This tool bit is used in manual and CNC lathes for a range of metal-removal applications including straight turning, boring, chamfering, and interrupted cuts. The left-hand cutting direction is appropriate for facing operations and shoulder work where the tool must feed toward the tailstock. The C2 carbide grade handles cast iron, non-ferrous metals, and general steel at moderate cutting speeds. It is a direct-fit replacement for any application calling for an industry-standard BL-12 single-point tool bit with a 3/4-inch square shank.

Key Features

• BL-style geometry with a 15-degree lead angle for controlled chip flow during turning operations
• C2-grade solid carbide tip provides wear resistance for general-purpose metal cutting
• 3/4 inch by 3/4 inch square shank fits standard tool post holders designed for BL-12 tooling
• Left-hand cutting direction for rightward-feed turning and shoulder operations
• Suited for boring, chamfering, interrupted cuts, and straight turning in a single tool
• 4.5-inch overall length compatible with common lathe tool post setups

Compatibility

Designed as a direct replacement for industry-standard BL-12 single-point tool bits. Fits any tool post or holder that accepts a 3/4-inch by 3/4-inch square shank and is rated for left-hand cutting direction.

Installation Notes

Installation is performed by qualified machinists or tool-and-die technicians. Ensure the lathe spindle is fully stopped and locked out before changing or adjusting tool bits. The tool bit should be set on center height using shims appropriate for the lathe and secured firmly in the tool post to prevent chatter during interrupted cuts. Refer to the machine tool manufacturer guidelines and applicable shop safety standards when setting cutting speeds and feed rates for the workpiece material.
