M.a. Ford. 20505200 Screw Machine Drill Bit 0.052 in

Product Description

The M.A. FORD. 20505200 is a screw machine length drill bit designed for precision drilling in tight-clearance applications. Built from solid carbide, this bit delivers the rigidity and heat resistance needed when drilling hard materials at high feeds. The 135-degree split point promotes self-centering and reduces walking on entry, while the web-thinned design lowers thrust and improves chip evacuation. At 0.052 inches in diameter and 1.625 inches in overall length, it is suited to production drilling environments where stub-length stiffness matters. Licensed HVAC, plumbing, and general trade machinists use bits like this where hole-location accuracy and tool life are critical.

This bit is intended for use on cast iron, non-ferrous metals, stainless steel, and steel. The screw machine (stub) length format makes it a practical choice on CNC machining centers, drill presses, and turret lathes where reduced overhang and minimized deflection are priorities. The slow-spiral flute geometry helps control chip flow in gummy or abrasive materials, making it well matched to production runs on difficult workpiece materials.

Key Features

• Solid carbide construction for superior rigidity and extended tool life in hard and abrasive materials
• 135-degree drill point angle with web thinning for self-centering entry and reduced thrust
• Slow-spiral flute geometry promotes controlled chip evacuation in cast iron and stainless steel
• Bright/uncoated finish suitable for use across a wide range of workpiece materials
• Straight-cylindrical shank at 0.052 inches diameter fits standard collets and drill chucks
• Diameter tolerance of +0.0000 to -0.0005 inches ensures precise hole sizing

Compatibility

Designed as a screw machine length replacement drill bit for applications requiring a wire gauge number 55 (0.0520 inch) hole in cast iron, non-ferrous metal, stainless steel, and steel workpieces. Part of M.A. FORD. Series 205.

Installation Notes

This bit is installed and used by machinists and toolroom technicians on CNC machines, drill presses, or turret lathes. Ensure the spindle and workpiece are fully secured before starting the cut. Use appropriate cutting fluid or coolant as required by the workpiece material, even though this bit does not have through-coolant capability. Inspect the cutting edges for wear or chipping before each use, as carbide bits can fracture if run in a worn or improperly indicated spindle.
