Micro 100 MBC-750 Back Chamfer Tool 3/4 in 6 Flute Carbide

Product Description

The MICRO 100 MBC-750 is a solid carbide back chamfer tool designed to produce clean chamfered edges on the reverse side of drilled holes and bored features. It runs a 3/4 inch cutter head diameter with a 90 degree included angle and a 0.156 inch chamfer width, making it well-suited for deburring and edge-breaking operations where access from the front face is not possible. The tool measures 2.66 inches overall length and carries a bright uncoated finish. With 6 flutes, it delivers consistent chip evacuation and a smooth surface finish in a single pass. Machinists and tool-and-die professionals reach for this geometry when working on back-side features in production or job-shop environments.

The MBC-750 is intended for use on machined components requiring back chamfering at a 90 degree included angle. Typical applications include chamfering counterbored holes, intersecting bore edges, and cross-drilled passages where a standard chamfer mill cannot reach the trailing edge. It is appropriate for use in CNC machining centers and manual mills on materials compatible with solid carbide tooling. The bright uncoated finish makes it a practical choice for non-ferrous metals, plastics, and other materials where a coated tool is not required.

Key Features

• 3/4 inch cutter head diameter for consistent back chamfer geometry
• 90 degree included angle produces standard chamfer profile on reverse bore edges
• 0.156 inch chamfer width with 0.031 inch flat width for controlled edge break
• 6 flutes for efficient chip removal and improved surface finish
• Solid carbide construction provides rigidity and wear resistance
• Bright uncoated finish suits non-ferrous and non-abrasive material applications

Compatibility

Designed as an OEM-style solid carbide back chamfer tool suitable for CNC and manual milling applications requiring reverse-side chamfering on drilled or bored holes.

Installation Notes

Installation and use of this tool should be performed by a qualified machinist familiar with rotary cutting tool setup. Secure the tool shank in a properly sized collet or tool holder and verify runout before cutting. Always power down the spindle and confirm the machine is in a safe state before changing tooling. Follow the machine tool manufacturer guidelines and applicable shop safety procedures for speeds and feeds when setting up back chamfer operations.
