M.a. Ford. 20627200 Carbide Screw Machine Drill Bit 0.272in

Product Description

The M.A. FORD. 20627200 is a solid carbide screw machine length drill bit sized at 0.272 inches (Letter I) in diameter, designed for high-performance drilling in demanding shop and production environments. Built to Series 206 specifications, it features a 118-degree faceted point angle with web thinning for reduced thrust and cleaner entry. The straight-cylindrical shank measures 0.2720 inches in diameter and the overall length is 2.5 inches, making it a compact, rigid tool suited for CNC machining centers, drill presses, and screw machine applications. A bright, uncoated finish keeps the carbide surface in its natural state for general-purpose use across a range of workpiece materials.

This drill bit is intended for use in production and job-shop drilling operations on cast iron, non-ferrous metals, stainless steel, and carbon steel. The short flute-to-diameter ratio of 3xD and screw machine (stub) length body minimize deflection and improve hole location accuracy, particularly in close-tolerance fixture work. It is well suited for machinists, tool-and-die makers, and maintenance technicians requiring consistent performance in repetitive-cycle drilling programs.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• 118-degree faceted point with web thinning reduces entry thrust and improves centering
• Screw machine (short) length body minimizes deflection in precision drilling applications
• Straight-cylindrical shank at 0.2720 inches fits standard drill chucks and collets without modification
• Right-hand cut, 2-flute spiral configuration for efficient chip evacuation
• Diameter tolerance of +0.0000 to -0.0005 inches supports close-tolerance hole requirements
• No coolant-through feature; suited for external coolant or dry cutting setups

Compatibility

Rated for primary use in cast iron, non-ferrous metal, stainless steel, and steel workpieces. Fits any spindle or chuck accepting a 0.2720-inch straight-cylindrical shank, including standard drill chucks, ER collet systems, and screw machine spindles.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or tooling technicians familiar with cutting tool safety practices. Secure the shank fully in the chuck or collet and verify runout before initiating a cut. Power down and lock out the spindle before changing tooling. Do not exceed the recommended feed and speed parameters for solid carbide in the target workpiece material, as carbide is brittle and susceptible to fracture under shock loading or improper setup.
