M.a. Ford 61018702 82 Degree Hss Countersink 3/16 Inch

Product Description

The M.A. FORD 61018702 is a single-flute, high-speed steel countersink designed for chamfering, countersinking, and deburring operations in metalworking and light fabrication applications. Built with a straight cylindrical shank measuring 3/16 inches in diameter and an overall length of 1.5 inches, this tool offers a compact profile suited for tight clearance drilling setups. The 82-degree included angle is the standard for flathead fastener seating in aerospace and general metalworking applications. The bright uncoated finish provides a clean, consistent surface without added coating thickness, which is preferred when dimensional precision at the cutting edge matters most. No pilot is included, and the tool features a single-end configuration with a 0.045-inch tip diameter.

This countersink is suited for use in manual drill presses, CNC machining centers, and hand-operated applications where a controlled, accurate countersink seat is required. It performs across a broad range of workpiece materials including mild steel, alloy steel, stainless steel, cast iron, aluminum, brass, magnesium alloy, high-nickel steel, high-tensile steel, Monel, and plastic. The single-flute geometry makes it a reliable choice when chatter reduction and smooth finish quality are priorities over aggressive material removal rates.

Key Features

• 82-degree included angle for standard flathead fastener seating in metalworking and aerospace applications
• Single-flute design reduces chatter and produces a cleaner finish in the countersunk seat
• High-speed steel construction provides durability across a wide range of workpiece materials
• Bright uncoated finish maintains precise edge geometry without coating buildup
• Compact 1.5-inch overall length fits tighter setups and shorter reach requirements
• Straight cylindrical shank ensures consistent grip in standard drill chucks and collets

Compatibility

Designed as a general-purpose OEM-style single-flute countersink compatible with standard drill chucks and collets accepting a 3/16-inch straight cylindrical shank, suitable for use on manual drill presses and CNC equipment.

Installation Notes

This tool is typically installed and operated by machinists, tool and die technicians, or maintenance professionals using a drill press, milling machine, or hand drill with a compatible chuck or collet. Secure the shank firmly in the chuck before operation and verify spindle runout is within acceptable tolerance to prevent uneven countersink geometry. Always reduce spindle speed when transitioning to harder workpiece materials such as stainless or high-nickel steel. Inspect the cutting edge for wear before each use, as a single-flute geometry concentrates cutting load on one edge.
