M.a. Ford. 22406690 Carbide Jobber Drill 0.0669 in 118 Deg

Product Description

The M.A. FORD. 22406690 is a solid carbide jobber-length drill bit designed for precision hole-making in demanding materials. It features a 0.0669 inch diameter cutting edge with a 118-degree faceted point and a bright/uncoated finish. The two-flute, right-hand spiral design produces clean, consistent holes in a range of ferrous and non-ferrous workpiece materials. With an overall length of 43.00 mm and a web-thinned, tapered web configuration, this bit is suited for general-purpose drilling where tight tolerances and tool life matter. Machinists, tool-and-die technicians, and production drilling operations are the typical end users.

This jobber drill is built for general-purpose drilling in cast iron, non-ferrous metals, stainless steel, and steel. Its 5xD flute-to-diameter ratio and regular spiral type make it a practical choice for both manual and CNC machine setups requiring small-diameter, close-tolerance hole work. The straight-cylindrical shank with a 0.0700 inch shank diameter fits standard collets and drill chucks used in vertical machining centers, drill presses, and hand-held power tools.

Key Features

• Solid carbide construction for extended tool life in hard and abrasive materials
• 118-degree faceted point promotes accurate hole entry and reduces walk-off
• Web-thinned, tapered web lowers thrust force requirements during drilling
• Bright/uncoated finish compatible with a wide range of cutting fluids and dry applications
• Right-hand, two-flute spiral design for efficient chip evacuation
• Manufactured to DIN 338 specification and produced under ISO 9001:2015 certified processes

Compatibility

Designed as a general-purpose replacement or stock drill bit for applications requiring a 0.0669 inch diameter solid carbide jobber drill. Suitable for use in cast iron, non-ferrous metal, stainless steel, and steel workpieces as identified by workpiece material codes K, M, N, and P.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or tooling technicians familiar with small-diameter carbide tooling. Secure the straight-cylindrical shank firmly in a properly sized collet or drill chuck before operation, and verify runout is within acceptable limits to avoid bit breakage. Carbide tooling is brittle and susceptible to chipping from side loads or improper feed rates, so follow the machine manufacturer and tooling guidelines for speeds and feeds. Inspect the cutting edges before each use and replace any bit showing signs of chipping or wear.
