M.a. Ford. 20607300 Solid Carbide Screw Machine Drill Bit

Product Description

The M.A. FORD. 20607300 is a screw machine length (short series) drill bit engineered for precision drilling in demanding trade and industrial applications. Built from solid carbide with a bright/uncoated finish, this bit measures 0.073 inches in diameter and carries a 118-degree faceted drill point angle. The two-flute spiral design with web thinning reduces thrust and improves chip evacuation. At 1.5 inches overall length, it is sized for use in screw machine and CNC drilling operations where rigidity and hole accuracy are critical. Licensed machinists, tool and die technicians, and precision fabricators are the typical end users.

This bit is suited for short-reach drilling operations in cast iron, non-ferrous metals, stainless steel, and carbon steel. Its straight-cylindrical shank seats directly into standard drill chucks and collet holders. The 3xD flute-to-diameter ratio and parallel web configuration make it a reliable choice for production environments where consistent hole diameter tolerance is required. It is well matched to CNC machining centers, drill presses, and screw machine setups handling tight-tolerance work in ferrous and non-ferrous stock.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive workpiece materials
• 118-degree faceted drill point with web thinning for reduced entry thrust and accurate self-starting
• Bright/uncoated finish compatible with a wide range of cutting fluids and dry cutting applications
• Right-hand spiral flute geometry promotes efficient chip clearance in short-hole applications
• Straight-cylindrical shank at 0.073 inches diameter fits standard collets and drill chucks
• Tight diameter tolerance of +0.0000 to -0.0005 inches supports consistent finished hole size

Compatibility

Designed as a Series 206 screw machine length carbide drill bit suitable for cast iron, non-ferrous metal, stainless steel, and steel workpieces in standard drill chuck and collet toolholding systems.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians familiar with cutting tool safety practices. Ensure the spindle and workpiece are fully secured before initiating a cut. Use appropriate cutting fluid or coolant based on workpiece material unless dry cutting is intentional. Inspect the bit for chipping or wear before each use, as solid carbide is brittle and prone to fracture if run in a worn or misaligned setup.
