Accupro 330-MG Single Point Tool Bit 3/4 in Lh Carbide

Product Description

The ACCUPRO 330-MG is a left-hand, BL-style single point tool bit designed for lead angle turning operations on metalworking lathes and boring machines. The cutting tip is solid carbide, micrograin grade, offering the edge retention and shock resistance needed for interrupted cuts and demanding turning applications. The shank measures 3/4 inches wide by 3/4 inches high with a 4-1/2 inch overall length, and the 1/32 inch nose radius suits general-purpose finishing and semi-finishing passes. This tool is installed and used by machinists and toolroom technicians working on manual or CNC lathes.

The 330-MG is suited for boring, chamfering, interrupted cuts, and general turning in both production and job-shop environments. The left-hand cutting direction makes it appropriate for operations where the tool feeds from left to right relative to the workpiece. The micrograin carbide tip grade performs well in steel, cast iron, and non-ferrous materials where consistent edge geometry is required across multiple passes. Typical applications include shaft turning, bore finishing, and chamfer work on short to medium production runs.

Key Features

• Micrograin solid carbide tip for extended edge life and resistance to chipping on interrupted cuts
• Left-hand cutting direction for right-to-left feed setups
• BL tool bit style with industry standard number BL-12
• 3/4 inch by 3/4 inch shank cross-section fits standard tool posts and holders in that size class
• 1/32 inch nose radius suitable for general finishing and semi-finishing passes
• Rated for boring, chamfering, interrupted cuts, and turning operations

Compatibility

Designed as an OEM-style single point tool bit for use in standard 3/4 inch tool holders and indexable or brazed-tip tool post setups on manual and CNC lathes accepting BL-style geometry.

Installation Notes

Installation is performed by a machinist or toolroom technician. The machine spindle must be stopped and all energy sources locked out before seating or adjusting the tool bit in the holder. Secure the shank fully within the tool post or holder to the manufacturer-specified clamping depth to prevent chatter and tool pullout. Confirm cutting direction and lead angle orientation match the intended feed direction before beginning any cut.
