M.a. Ford. 61018704 Single Flute Countersink 100 Degree Hss

Product Description

The M.A. FORD. 61018704 is a single-flute, high-speed steel countersink designed for chamfering, countersinking, and deburring operations in metalworking and fabrication applications. It features a 100-degree included angle (50-degree centerline angle) and a straight-cylindrical shank measuring 3/16 inches in diameter. Overall length is 1.5 inches, with a tip diameter of 0.045 inches. The bright, uncoated finish suits general-purpose use across a wide range of materials. Right-hand cutting direction makes it compatible with standard drill press and hand-drill setups. Machinists, tool-and-die technicians, and fabrication pros are the primary installers of this tool.

This countersink is suited for light-duty chamfering and deburring work on holes in alloy steel, mild steel, stainless steel, cast iron, aluminum, brass, magnesium, magnesium alloy, high-nickel steel, high-tensile steel, Monel, and plastic. Its compact 1.5-inch overall length makes it practical for use in tight workspaces or on small workpieces. The straight-cylindrical shank seats directly into standard drill chucks without requiring a dedicated holder. It does not include a pilot and is sold as a head-and-shank unit, not a head-only component.

Compatibility

Designed for use in standard drill presses, CNC machines, and hand drills with a 3/16-inch chuck capacity. Compatible material applications include alloy steel, aluminum, brass, cast iron, high-nickel steel, high-tensile steel, magnesium, magnesium alloy, mild steel, Monel, plastic, and stainless steel.

Installation Notes

This tool is installed by machinists and fabricators in machine shop and production environments. Secure the straight-cylindrical shank firmly in the drill chuck before operation and confirm the spindle speed is appropriate for the workpiece material and tool diameter. De-energize or power down any machine tool fully before changing or seating this countersink. Do not exceed the tool's recommended feed and speed parameters for the material being cut.
