M.a. Ford 20714060 Screw Machine Drill Bit 9/64 Carbide

Product Description

The M.A. FORD 20714060 is a screw machine length drill bit designed for short-reach, high-rigidity drilling in metalworking and machining applications. Built from solid carbide, it delivers superior hardness and wear resistance compared to high-speed steel alternatives. The bit measures 0.1406 inches (9/64 inch) in diameter with an overall length of 1-15/16 inches and a flute length of 11/16 inches. Its compact screw machine length profile reduces deflection and improves hole accuracy in CNC machine tools, drill presses, and screw machines. The bright/uncoated finish makes it suitable for use with cutting fluids across a range of materials.

This drill bit is suited for production machining environments where short-length, high-accuracy drilling is required. Typical applications include drilling in steel, aluminum, brass, and other non-ferrous metals on CNC lathes, machining centers, and automatic screw machines. The 9/64-inch diameter fits within the Series 207 range of 0.1000 to 0.1500 inches, making it a practical selection when working through that decimal-inch size range. It is commonly used by machinists, toolroom technicians, and production floor operators in light-to-medium duty drilling operations.

Key Features

• Solid carbide construction for extended tool life and heat resistance
• Screw machine length (1-15/16 inches overall) provides added rigidity and reduced runout
• Right-hand cut with regular spiral flute for efficient chip evacuation
• Straight-cylindrical shank for standard drill chuck and collet compatibility
• Web-thinned parallel web geometry reduces thrust and improves penetration
• Bright/uncoated finish compatible with a wide range of cutting fluids

Compatibility

Designed as an OEM-style replacement and direct-fit screw machine length drill bit for applications within the Series 207 decimal-inch range of 0.1000 to 0.1500 inches. Compatible with standard straight-shank drill chucks and collets sized for a 9/64-inch diameter shank.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom personnel familiar with carbide tooling. Secure the straight-cylindrical shank firmly in a collet or drill chuck rated for the spindle speed before operation. Carbide tooling is brittle — avoid side loads, interrupted cuts without proper setup, or dropping the bit, as these can cause chipping or fracture. Follow machine tool manufacturer guidelines for spindle speed and feed rate when working with carbide bits in this diameter range.
