M.a. Ford 20404300A Jobber Drill Bit 0.0430 in Carbide

Product Description

The M.A. FORD 20404300A is a jobber length drill bit designed for precision drilling in demanding trade and industrial applications. Built from solid carbide with an ALtima TiN coating, this bit delivers extended tool life and heat resistance compared to standard high-speed steel tooling. It features a 118-degree four-facet point with web thinning for accurate, self-centering starts and reduced thrust. At 0.0430 inches in diameter and 1.5 inches overall length, it falls in the wire gauge #57 size range. The spiral flute geometry promotes efficient chip evacuation during drilling operations.

This bit is suited for drilling cast iron, non-ferrous metals, stainless steel, and steel in general-purpose machining environments. The right-hand spiral flute design and straight cylindrical shank make it compatible with standard drill chucks and CNC machining centers. With a 5xD flute-to-diameter ratio and a 0.75-inch flute length, it handles moderate-depth holes typical of precision fabrication, toolroom, and production drilling work. Machinists, tool-and-die technicians, and shop floor operators are the primary users.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous and non-ferrous materials
• ALtima TiN coating reduces friction and extends cutting life
• 118-degree four-facet point with web thinning for accurate entry and reduced walking
• Right-hand cut with regular spiral flute for effective chip removal
• Straight cylindrical shank fits standard drill chucks and collets
• Manufactured to ISO 9001:2015 certified standards

Compatibility

Designed as a general-purpose replacement or production drill bit for applications involving cast iron, non-ferrous metal, stainless steel, and steel workpieces. Compatible with standard straight-shank drill chucks and collet systems sized for 0.0430-inch shanks.

Installation Notes

Installation and use should be performed by qualified machinists or tool technicians familiar with small-diameter carbide tooling. Always secure the shank fully in the chuck or collet before running the spindle. Carbide is brittle - avoid side loading, interrupted cuts without reduced feed rates, or dropping the bit on hard surfaces. Verify spindle speed and feed rate recommendations for the specific workpiece material before beginning a cut.
