M.a. Ford 20606250 Screw Machine Drill Bit 1/16 in

Product Description

The M.A. FORD 20606250 is a solid carbide screw machine length drill bit with a 1/16 inch (0.0625 inch) diameter and a 118-degree faceted drill point angle. Designed for short-reach, high-precision drilling in tight setups, it features a right-hand spiral flute with a web-thinned, parallel web configuration to reduce thrust and improve chip evacuation. The straight-cylindrical shank measures 0.0625 inches in diameter and 1.125 inches in length. Overall length is 1.5 inches with a 3/8 inch flute length. This bit is suited for machining operations where a stub-length drill is required for rigidity and accuracy.

This drill bit is intended for use on cast iron, non-ferrous metals, stainless steel, and steel workpieces. The Series 206 screw machine length format is a common choice in production machining, toolroom environments, and precision drilling applications where standard jobber-length bits introduce too much deflection. It is sized for use in CNC machining centers, drill presses, and manual machine setups where a 1/16 inch diameter stub drill is specified.

Key Features

• Solid carbide construction for hardness and wear resistance in ferrous and non-ferrous materials
• 118-degree faceted point angle with web-thinned parallel web for reduced entry force
• Right-hand cut with regular spiral flute for efficient chip removal
• Screw machine (stub) length at 1.5 inches overall for increased rigidity
• Bright/uncoated finish compatible with a wide range of cutting fluids and materials
• Diameter tolerance held to +0.0000 to -0.0005 inches for close-tolerance hole sizing

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide stub drill for production machining applications in cast iron, non-ferrous metal, stainless steel, and steel. Compatible with any machine tool or drill chuck accepting a 0.0625 inch straight-cylindrical shank.

Installation Notes

Installation and use should be performed by a qualified machinist or tooling technician. Secure the shank fully in a drill chuck or collet rated for the spindle speed required for the workpiece material and bit diameter. At small diameters such as 1/16 inch, use appropriate low feed rates to avoid bit breakage. Ensure the workpiece is clamped securely and that cutting fluid or coolant is applied per shop practice for the material being drilled.
