Accupro MB035150 Boring Bar Submicron Solid Carbide

Product Description

The ACCUPRO MB035150 is a solid carbide boring bar designed for precision internal boring operations on CNC lathes and manual turning centers. Built from submicron-grade carbide with a bright finish coating, it delivers tight dimensional control at very small bore diameters. The bar features a right-hand cutting direction and a minimum bore diameter of 0.035 inches, making it well suited for fine-detail work in hard and abrasive materials. With an overall length of 1.5 inches and a 0.125-inch shank diameter, this is a compact tool intended for close-tolerance applications where rigidity and edge retention are critical.

This boring bar is used in precision machining environments including tool rooms, production shops, and job shops handling small-component work. Typical applications include boring tight-tolerance holes in hardened steels, stainless alloys, and non-ferrous metals. The submicron carbide grade provides the edge stability needed for consistent surface finish in interrupted or continuous cuts. It is installed by machinists and tool-and-die professionals working on lathes or machining centers requiring small-bore capability.

Key Features

• Minimum bore diameter of 0.035 inches for very small internal features
• Maximum bore depth of 0.15 inches suitable for shallow precision bores
• Submicron solid carbide construction for superior hardness and wear resistance
• Bright finish coating to reduce friction and aid chip evacuation
• Right-hand cutting direction for standard lathe and turning center setups
• Compact 0.125-inch shank diameter fits standard small-bore toolholders

Compatibility

Designed as an OEM-style replacement or direct-fit boring bar for lathes and turning centers equipped with toolholders accepting a 0.125-inch round shank.

Installation Notes

Installation should be performed by a qualified machinist following standard toolroom procedures. Power down and lock out the machine before seating or removing the boring bar from the toolholder. Ensure the shank is fully seated and clamped per the toolholder manufacturer's specifications before starting the spindle. Inspect the cutting edge for chips or wear prior to each use, as submicron carbide is brittle and sensitive to improper handling.
