M.a. Ford. 20506250T 1/16 in Carbide Screw Machine Drill Bit

Product Description

The M.A. FORD. 20506250T is a screw machine length drill bit designed for high-precision drilling in tight-clearance applications. Built from solid carbide with a coated finish, this bit measures 0.0625 inches (1/16 inch) in diameter with an overall length of 1.625 inches and a flute length of 0.625 inches. The 135-degree split point reduces walking and thrust at entry, while the web-thinned, parallel web construction improves chip evacuation and cutting efficiency. Right-hand cutting with a slow spiral flute pattern makes this bit well suited for materials that demand controlled chip flow and edge stability.

This drill bit is intended for use on cast iron, non-ferrous metals, stainless steel, and steel. The screw machine length body - shorter than a jobber-length bit - provides added rigidity, making it a preferred choice for CNC machining centers, drill presses, and screw machine operations where runout must be minimized. The straight-cylindrical shank seats securely in standard drill chucks and collets. Series 205 positions this bit within M.A. FORD.s line of general-purpose solid carbide drilling tools.

Key Features

• Solid carbide construction for hardness and heat resistance in demanding materials
• 135-degree split point minimizes entry walking and reduces required thrust
• Web-thinned parallel web improves chip evacuation and cutting efficiency
• Slow spiral flute geometry optimized for cast iron, stainless steel, and non-ferrous metals
• Screw machine length body provides extra rigidity over standard jobber-length bits
• Diameter tolerance of +0.0000 to -0.0005 inches for precise hole sizing

Compatibility

Designed for use in standard drill chucks and collets accepting a 0.0625-inch straight-cylindrical shank. Suitable for drilling cast iron, non-ferrous metal, stainless steel, and steel workpieces in CNC and manual machine tool setups.

Installation Notes

This bit is installed and serviced by machinists and toolroom professionals. Secure the shank fully in the collet or chuck before operation and verify runout with a dial indicator when precision hole tolerances are required. Always follow machine manufacturer guidelines for spindle speeds and feed rates appropriate to the workpiece material and bit diameter. Inspect the cutting edges and coating for wear before each use; carbide is hard but brittle and should not be dropped or subjected to side-loading.
