Value Collection 383-1186 BL-16 Tool Bit Left Hand

Product Description

The VALUE COLLECTION 383-1186 is a BL-style single-point tool bit designed for lead angle turning operations on manual and CNC lathes. It features a solid carbide tip rated at grade C6, suited for interrupted cuts, boring, chamfering, and general turning work. The shank measures 1 inch in height and 1 inch in width, with an overall length of 6 inches. The 15-degree lead angle and left-hand cutting direction make this bit appropriate for specific approach geometries where a right-hand bit would not clear. Machinists and toolroom technicians are the primary installers and users of this tool bit.

This tool bit is intended for use in metalworking environments where a left-hand, lead angle turning tool is required. Typical applications include facing cuts moving toward the tailstock, undercutting, and finishing operations on lathes equipped with a square tool post or quick-change tool holder that accepts a 1-inch shank. The C6 carbide grade is generally suited for machining cast iron, non-ferrous metals, and hard materials where wear resistance and edge retention are priorities.

Key Features

• BL-16 industry standard designation for consistent cross-brand holder compatibility
• Solid carbide tip at grade C6 for wear resistance on hard and abrasive materials
• Left-hand cutting direction for tailstock-approach and undercutting operations
• 15-degree lead angle for controlled chip flow and reduced entry shock on interrupted cuts
• 1 inch by 1 inch square shank fits standard BL-style tool holders
• 6 inch overall length provides adequate reach for most engine lathe setups

Compatibility

Designed as an OEM-style replacement and standard fit for BL-style square shank tool holders accepting a 1-inch shank height and 1-inch shank width, consistent with the BL-16 industry standard designation.

Installation Notes

This tool bit is installed and set by a machinist or toolroom technician. Before changing or indexing any tool bit, ensure the lathe spindle is fully stopped and the machine is powered down or in a locked-out state per facility lockout-tagout procedures. The bit should be seated fully in the holder and clamped securely before taking any cut. Do not use a tool bit that shows chipping, cracking, or edge breakdown, as carbide can fracture unpredictably under interrupted cut loads.
