M.a. Ford 40203100 Combo Drill Countersink 1/8 in Solid Carbide

Product Description

The M.A. FORD 40203100 is a solid carbide combo drill countersink designed for simultaneous drilling and countersinking in a single pass. Built to Series 402 specifications, this tool features a 1/8 inch body diameter, a 1/32 inch drill point diameter, and a 60-degree included angle. The bright polished finish reduces friction and aids chip evacuation. At 1-1/2 inches overall length, it is a long-length tool suited for precision work in tight or hard-to-reach locations. The right-hand cut and double end type provide efficient material removal with consistent countersink geometry on each pass.

This combo drill countersink is rated for use on cast iron, hardened steel, special alloys, stainless steel, and general steel. It is appropriate for both production machining environments and precision fabrication work where pre-drilling and countersinking must be completed in one operation. The plain cutting edge style and non-tapered, non-insertable design make it straightforward to set up and run on a drill press, CNC machining center, or manual mill. Machinists, tool-and-die technicians, and maintenance mechanics working on metal fabrication or repair tasks are the primary users.

Key Features

• Solid carbide construction for extended tool life in hard and abrasive workpiece materials
• 60-degree included angle delivers standard countersink geometry in one step
• Double end type provides two usable cutting ends, extending service interval
• Bright polished finish minimizes friction and promotes chip flow
• Long-length design allows access in deeper or recessed workpiece locations
• Right-hand cut compatible with standard spindle rotation on most machine tools

Compatibility

The 40203100 is rated for use on cast iron, hardened steel, special alloys, stainless steel, and carbon steel workpieces. It is an OEM-style cutting tool designed for trade size 0 applications requiring a 1/8 inch body diameter in Series 402 format.

Installation Notes

This tool is installed and operated by machinists or maintenance technicians using a drill press, manual mill, or CNC machining center. Always secure the workpiece firmly and confirm spindle speed is appropriate for carbide tooling in the target material before engaging the cut. Inspect the cutting ends for chipping before each use, as carbide is brittle and sensitive to impact or side-loading. Power down and lock out the machine before changing or inspecting the tool.
