M.a. Ford 20467190 Carbide Jobber Drill Bit 43/64 Inch

Product Description

The M.A. FORD 20467190 is a solid carbide jobber length drill bit designed for precision hole-making in demanding industrial and machining applications. Measuring 43/64 inches (0.6719 inches decimal) in diameter with a 118-degree faceted point angle, this bit delivers consistent entry geometry and controlled chip evacuation. The bright uncoated carbide construction provides excellent hardness and wear resistance without added coating thickness, making it well suited for tight-tolerance bores. The 2-flute regular spiral design supports efficient chip clearing through a flute length of 3.625 inches along a 5.5-inch overall length. Web thinning reduces thrust requirements at the point, which matters when drilling into harder substrates.

This drill bit targets metalworking professionals, machinists, and toolroom technicians who work with cast iron, non-ferrous metals, stainless steel, and carbon or alloy steel. The 5xD flute-to-diameter ratio makes it appropriate for jobber-depth holes in general-purpose production environments, whether on a drill press, CNC machining center, or manual mill. The straight cylindrical shank seats in standard drill chucks and collet-style toolholders without modification. It carries ISO 9001:2015 certification, reflecting consistent manufacturing quality from M.A. FORD Series 204.

Key Features

• Solid carbide construction for high hardness and long tool life in ferrous and non-ferrous materials
• 118-degree faceted drill point with web thinning to reduce entry thrust and improve centering
• 2-flute regular spiral geometry promotes efficient chip evacuation
• Bright uncoated finish maintains full carbide diameter without coating buildup for close-tolerance work
• Straight cylindrical shank fits standard chucks and collet holders
• ISO 9001:2015 certified manufacturing

Compatibility

Designed as a general-purpose solid carbide jobber drill for use in cast iron, non-ferrous metals, stainless steel, and steel workpieces. Compatible with any machine spindle or drill chuck that accepts a 43/64-inch straight cylindrical shank.

Installation Notes

This tool is installed and operated by machinists or toolroom technicians on drill presses, manual mills, or CNC machining centers. Secure the shank fully in the chuck or collet before powering the spindle, and verify runout is within acceptable tolerance for the application. Solid carbide tooling is brittle - avoid side loading, interrupted cuts without appropriate feed adjustments, or dropping the bit on hard surfaces. Consult machine manufacturer feed and speed recommendations for the specific workpiece material before use.
