Magafor 81155030000 Combo Drill Countersink Size 3 Hss

Product Description

The MAGAFOR 81155030000 is a combination drill and countersink tool designed to drill a pilot hole and form a 90-degree countersink in a single pass. Built from high-speed steel with a bright, uncoated finish, it delivers consistent cutting performance across a range of metal and wood applications. The body measures 1/4 inch in diameter with a 7/64 inch point diameter and a 2-inch overall length. The right-hand cutting geometry and plain cutting edge style make it a straightforward choice for machinists, tool-and-die technicians, and fabricators working at the drill press or CNC machine.

This tool belongs to MAGAFOR Series 155 and is sized as a Trade Size 3 combo drill countersink. It is suited for countersinking applications in light fabrication, sheet metal work, and general machining where a 90-degree included angle seat is required. The double end type extends tool life by providing two usable cutting ends. It is not an aircraft-style tool and is not designed for long-reach or tapered applications.

Installation Notes

This tool is installed and used by machinists, fabricators, and toolroom technicians. Secure the tool firmly in a drill chuck or collet rated for the shank diameter before operation. Power down and de-energize the machine spindle completely before changing or adjusting the tool. Do not exceed the recommended RPM range for the material being cut, and apply appropriate cutting fluid when working with hard metals to preserve cutting edge life.
