M.a. Ford. 20617700 Carbide Screw Machine Drill Bit

Product Description

The M.A. FORD. 20617700 is a solid carbide screw machine length drill bit designed for high-precision drilling in demanding industrial and machining applications. With a 0.177 inch (Wire Size 16) diameter and a 118-degree faceted point angle, this bit delivers clean, accurate entry in a wide range of workpiece materials. The bright/uncoated finish suits applications where coating is not required or where carbide hardness alone meets the job. The short-length geometry provides added rigidity, reducing deflection and improving hole accuracy in production environments. It is installed and used by machinists, tool and die technicians, and CNC operators.

This drill bit is suited for use on cast iron, non-ferrous metals, stainless steel, and carbon steel. The screw machine length profile is commonly specified for drill press, CNC machining center, and turret lathe applications where a stubby, rigid tool is preferred over jobber-length bits. The two-flute spiral design with a parallel web and web-thinned point supports efficient chip evacuation and reduced thrust force at entry. It fits standard straight-shank toolholders and collets sized for 0.177 inch shanks.

Key Features

• Solid carbide construction for hardness and wear resistance in ferrous and non-ferrous materials
• 118-degree faceted point angle with web thinning for reduced entry thrust and improved centering
• Bright/uncoated finish — no coating buildup to affect tolerance-critical hole diameters
• Right-hand cut, two-flute spiral design for efficient chip evacuation
• Straight-cylindrical shank at 0.177 inches for direct collet or chuck mounting
• Short screw machine length (2.125 inches overall) for maximum rigidity and minimal deflection

Compatibility

Designed as an OEM-style replacement or direct-fit option for Series 206 screw machine length carbide drill bits with a 0.177 inch diameter and straight-cylindrical shank, suitable for use in drill presses, CNC machining centers, and turret lathes accepting standard straight-shank toolholding.

Installation Notes

This bit is installed by machinists or CNC operators into a compatible collet, drill chuck, or toolholder rated for the 0.177 inch shank diameter. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify runout and toolholder concentricity before use to protect the carbide cutting edges, which are more brittle than high-speed steel and sensitive to side-loading. Carbide drills should not be used in hand-drill applications.
