Cleveland C46272 Combo Drill Countersink Size 11 Hss

Product Description

The CLEVELAND C46272 is a combination drill and countersink designed for simultaneous center drilling and countersinking in a single operation. Built from high-speed steel with a bright uncoated finish, this tool features a 1/8 inch body diameter, a 3/64 inch drill point diameter, and a 118-degree drill point angle. The bell-style cutting edge produces a 60-degree included angle countersink profile. With an overall length of 1.25 inches and a right-hand cut, the C46272 is sized for precise, small-diameter work in machine shop and fabrication environments. Licensed machinists and tool-and-die technicians are the primary installers.

This combo drill countersink is suited for use on manual and CNC lathes, mills, and drill presses in both job shop and production settings. Trade size 11 positions it for light-duty center drilling applications. It is engineered for use on alloy tool steel, aluminum, carbon steel, and cast iron workpieces, making it a versatile single-tool solution when a countersunk lead hole is required before turning or grinding operations.

Installation Notes

This tool is installed in a collet, drill chuck, or toolholder on a lathe, mill, or drill press by a qualified machinist. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain surface finish quality. Do not exceed the recommended RPM for the tool diameter and material combination.
