Micro 100 BB-050300S Boring Bar Right Hand Solid Carbide

Product Description

The MICRO 100 BB-050300S is a solid carbide boring bar designed for precision internal turning and bore finishing operations on CNC lathes and manual turning centers. With a minimum bore diameter of 0.05 inches and a maximum bore depth of 0.3 inches, this bar is built for tight, small-diameter work where rigidity and dimensional accuracy are critical. The 1/8-inch shank diameter and 1.5-inch overall length make it well-suited for compact toolholders and Swiss-style or micro-machining setups. The bright, uncoated finish allows for direct inspection of tool condition. Machinists and toolroom technicians working in precision shops are the primary installers and users of this tool.

This boring bar is intended for small-diameter internal bore applications in production and jobshop environments. Right-hand cutting direction means the tool cuts with conventional lathe rotation. The -0.0125-inch offset is factory-ground into the tool geometry and must be accounted for during setup and diameter compensation. It is appropriate for use in ferrous and non-ferrous materials where solid carbide substrate provides the required edge retention and stiffness at small diameters.

Key Features

• Minimum bore diameter of 0.05 inches supports very small-diameter internal work
• Solid carbide construction provides high rigidity and edge retention in small overhangs
• Right-hand cutting direction for standard lathe rotation
• Bright, uncoated finish for easy visual inspection of tool condition
• Factory-ground -0.0125-inch offset built into tool geometry
• 1/8-inch shank diameter fits compact and micro toolholding systems

Compatibility

Designed for use in toolholders accepting a 1/8-inch shank boring bar. Confirm toolholder bore diameter, clamping style, and minimum bore clearance before installation.

Installation Notes

Installation is performed by machinists or toolroom technicians familiar with lathe setup and boring bar alignment. Secure the shank fully within the toolholder with adequate clamping engagement before any cutting operation. Account for the -0.0125-inch offset when entering tool geometry into the machine control. Verify workpiece clearance and bore entry diameter before engaging the cut to avoid tool or workpiece damage.
