M.a. Ford. 22611810A Screw Machine Drill Bit 0.1181 in

Product Description

The M.A. FORD. 22611810A is a screw machine length (short series) drill bit machined from solid carbide for use in precision drilling applications. It carries a 3.00 mm (0.1181 inch) diameter with a matching straight-cylindrical shank of the same diameter, making it compatible with standard drill chucks and collet holders. The 118-degree point angle is a general-purpose geometry suited to a wide range of workpiece materials. With an overall length of 1.811 inches and a two-flute spiral design, this bit is built for stable, accurate holes in tight-tolerance work. It is coated for improved wear resistance and is ground for right-hand cutting. Machinists, tool-and-die technicians, and CNC operators are the primary users of this bit.

The 22611810A is designed for drilling into cast iron, non-ferrous metals, stainless steel, and general steel stock. The short flute length of 16.00 mm (approximately 0.630 inches) relative to diameter follows a 3xD flute-by-diameter ratio, which improves rigidity and chip evacuation in short-depth holes. This makes it well suited for screw machine work, CNC machining centers, and bench drill press operations where hole depth is limited and repeatability is critical. A single margin geometry supports precise hole wall finish.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive workpiece materials
• 118-degree drill point angle for general-purpose entry geometry across multiple material types
• Coated finish extends tool life by reducing friction and heat buildup at the cutting edge
• Short (screw machine) length series improves stability and reduces deflection in shallow-hole applications
• Straight-cylindrical shank fits standard drill chucks and collet toolholders without modification
• Right-hand cut with regular spiral flute for positive chip clearance during drilling

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide drill bit for machine tool setups requiring a 3.00 mm straight-shank drill in screw machine length, conforming to DIN specification standards and suitable for use in any spindle accepting a 0.1181-inch straight shank.

Installation Notes

Installation and use of this bit is performed by machinists or CNC technicians. Always secure the shank fully within the chuck or collet to the recommended engagement depth before operation, and verify that the spindle and workpiece are properly fixtured before beginning a cut. Ensure the machine is at a complete stop before changing or inspecting this bit. Do not exceed the bit diameter tolerance range of +0.000 to -0.013 mm when selecting replacement tooling for close-tolerance holes.
