M.a. Ford. 61050006 Countersink 120 Deg 1/2 in Hss

Product Description

The M.A. FORD. 61050006 is a single-flute high-speed steel countersink designed for chamfering, countersinking, and deburring operations in a wide range of metalworking and fabrication applications. It features a 120-degree included angle with a 1/2-inch head diameter and a 1/4-inch straight cylindrical shank. The 2-inch overall length and bright uncoated finish make it a straightforward, no-frills tool suited for machinists, tool-and-die technicians, and maintenance professionals working on production or repair tasks. The single-flute design reduces chatter and produces a clean, consistent seat finish on drilled holes.

This countersink is appropriate for use in manual drill presses, CNC machining centers, and hand-held pneumatic or electric drilling equipment. The 120-degree angle is commonly specified for countersinking fastener seats, chamfering hole edges, and deburring on a broad set of workpiece materials. It is well suited for both light production runs and one-off fabrication work across shop, field, and maintenance environments.

Key Features

• Bright uncoated high-speed steel construction — no coating to chip or delaminate
• Rated for use on alloy steel, aluminum, brass, cast iron, stainless steel, plastics, magnesium alloy, mild steel, high-tensile steel, Monel, and high-nickel steel

Compatibility

Rated for chamfering, countersinking, and deburring on alloy steel, aluminum, brass, cast iron, high-nickel steel, high-tensile steel, magnesium, magnesium alloy, mild steel, Monel, plastic, and stainless steel workpieces.

Installation Notes

Install into a standard drill chuck or collet accepting a 1/4-inch straight shank before starting the spindle. Secure the workpiece firmly and set spindle speed appropriate to the workpiece material and head diameter — consult published HSS speed-and-feed tables for each material type. Power down and de-energize the machine before changing or inspecting the tool. Wear appropriate eye protection and follow applicable shop safety and machine guarding requirements.
