M.a. Ford 2XDCR4844A Jobber Drill 31/64 Inch Solid Carbide

Product Description

The M.A. FORD 2XDCR4844A is a solid carbide jobber-length drill bit sized at 31/64 inches (0.4844 inches) in diameter with a 142-degree split-point geometry and ALtima (AlTiN) coating. It is built for high-performance drilling in demanding materials, including steel, stainless steel, and high-temperature alloys. The 1/2-inch straight cylindrical shank and regular spiral flute design keep chip evacuation consistent during deep-hole operations. Coolant-through capability supports extended tool life at elevated cutting speeds. This drill is used by machinists, toolroom technicians, and production drilling professionals in shop and CNC environments.

The 2XDCR4844A belongs to M.A. FORD Series 2XDCR, a 5xD flute-to-diameter ratio line intended for high-performance applications in ferrous and exotic alloy machining. Primary workpiece materials are steel (H code), stainless steel (M code), and high-temperature alloys (S code). With a 4-3/4-inch overall length, 2.83-inch flute length, and a maximum drilling depth of 2.625 inches, this bit is suited for through-hole and blind-hole work in precision manufacturing, aerospace component production, and heavy industrial fabrication.

Key Features

• Solid carbide construction for rigidity and heat resistance in hard material drilling
• ALtima (AlTiN) proprietary coating extends tool life in steel and stainless applications
• 142-degree point angle reduces thrust force and improves self-centering on entry
• Coolant-through design delivers coolant directly to the cutting zone for high-speed operation
• 1/2-inch straight cylindrical shank for compatibility with standard drill chucks and collet holders
• Meets DIN 6537 K standard; manufactured under ISO 9001:2015 certified processes

Compatibility

Designed as a high-performance OEM-style jobber drill for use in CNC machining centers and manual drilling equipment accepting a 1/2-inch straight shank; primary rated workpiece materials are steel, stainless steel, and high-temperature alloys per Series 2XDCR design intent.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or toolroom technicians. Secure the shank fully in a matched collet or drill chuck before operation and verify runout is within acceptable tolerance for the application. Coolant-through tooling requires a compatible spindle coolant delivery system; confirm machine compatibility before use. De-energize and lock out all machine power before changing or inspecting tooling.
