M.a. Ford. 20418900 Jobber Length Drill Bit Size 12

Product Description

The M.A. FORD. 20418900 is a jobber length drill bit in wire size 12 (0.1890 inches decimal), manufactured from solid carbide with a bright, uncoated finish. It features a 118-degree faceted drill point and a two-flute regular spiral configuration with web thinning for improved chip evacuation and point entry. The overall length is 2-3/4 inches with a 1-5/8-inch flute length. The straight-cylindrical shank diameter matches the drill diameter at 0.1890 inches. This bit is designed for general-purpose drilling applications and is installed by machinists, maintenance technicians, and metalworking tradespeople in production and field environments.

This drill bit is suited for use in cast iron, non-ferrous metals, stainless steel, and steel workpieces. The solid carbide construction supports higher cutting speeds and greater wear resistance compared to high-speed steel, making it appropriate for harder or abrasive materials encountered in metal fabrication, mechanical contracting, and industrial maintenance. The 5xD flute-to-diameter ratio provides adequate chip clearance for typical jobber-length drilling depths. Coolant-through capability is not available on this model, so external coolant application or dry cutting practices apply based on the workpiece material.

Key Features

• Solid carbide construction for high wear resistance in ferrous and non-ferrous metals
• 118-degree faceted point with web thinning for accurate entry and reduced thrust
• Bright, uncoated finish suitable for a broad range of general-purpose applications
• Straight-cylindrical shank at 0.1890 inches for standard drill chuck compatibility
• Regular spiral, two-flute design with tapered web configuration
• Manufactured to ISO 9001:2015 certified quality standards

Compatibility

Designed as a general-purpose jobber length drill bit for use in standard drill chucks accepting a 0.1890-inch straight-cylindrical shank. Rated for primary workpiece materials classified under material codes K, M, N, and P, covering cast iron, non-ferrous metal, stainless steel, and steel.

Installation Notes

Secure the shank fully in a keyed or keyless drill chuck before operation and verify runout before engaging the workpiece. Machinists and metalworking technicians should select feed rate and spindle speed appropriate to the workpiece material and machine type. Since this bit does not support coolant-through delivery, apply external cutting fluid or use dry-cutting technique as required by the material. Inspect the cutting edges for chipping or wear before each use, as solid carbide is brittle and sensitive to side loading or impact.
