M.a. Ford. 64100004 Countersink Set 4 Pc Hss 100 Degree

Product Description

The M.A. FORD. 64100004 is a 4-piece single-flute countersink set made from high speed steel with a bright polished finish. It covers a head diameter range of 1/4 inch to 1 inch, all ground to a 100-degree included angle, making the set suitable for standard fastener countersinking across a wide range of workpiece materials. The straight shank design and right-hand cutting direction are compatible with conventional drill presses, CNC machines, and hand-held power drills. The set ships in a plastic storage case. It is used by machinists, tool and die workers, and maintenance technicians in production and job-shop environments.

This countersink set is designed for countersinking operations on alloy steel, mild steel, stainless steel, cast iron, high tensile steel, high nickel steel, Monel, aluminum, aluminum alloy, magnesium, magnesium alloy, brass, and plastics. The 100-degree included angle suits a broad range of standard flat-head fastener applications in both ferrous and non-ferrous materials. The set is suited to light production runs and maintenance work where a range of head diameters is needed without switching between separate single-size tools.

Key Features

• 4-piece set covers 1/4 inch to 1 inch head diameter range in a single case
• 100-degree included angle ground on all four countersinks for consistent flat-head fastener seating
• Single-flute geometry provides clean entry and reduces chatter on softer non-ferrous materials
• High speed steel construction for durability across ferrous and non-ferrous workpiece materials
• Bright polished finish reduces built-up edge on aluminum, brass, and plastic cuts
• Straight shank fits standard drill chucks; right-hand cutting direction for conventional spindle rotation
• Plastic storage case keeps all four tools organized and protected between uses

Compatibility

Designed for countersinking operations in alloy steel, mild steel, stainless steel, cast iron, high tensile steel, high nickel steel, Monel, aluminum, aluminum alloy, magnesium, magnesium alloy, brass, and plastics. Straight shank fits standard drill press and power drill chucks.

Installation Notes

Countersinks are installed and operated by machinists or maintenance technicians using a drill press, milling machine, or hand-held power drill with a standard chuck. Secure the workpiece before operation and select a spindle speed appropriate for the workpiece material and tool diameter. Inspect the cutting edge before each use and replace any tool showing chipping or dulling to maintain seat quality and prevent fastener fit issues. Store tools in the provided case when not in use to protect cutting edges.
