M.a. Ford. 20501450 Carbide Screw Machine Drill Bit

Product Description

The M.A. FORD. 20501450 is a solid carbide screw machine length drill bit designed for high-precision, short-reach drilling applications. Built to Series 205 specifications, it features a 135-degree split point with web thinning for reduced thrust and faster penetration on hard materials. The 0.0145-inch shank diameter and 1.5-inch overall length make it suited for close-tolerance work in confined setups. Two helical flutes with a slow spiral promote chip evacuation while maintaining rigidity. The coated finish extends tool life in demanding materials. Machinists, toolroom technicians, and precision metalworking shops are the primary installers of this bit.

This drill bit is designed for drilling cast iron, non-ferrous metals, stainless steel, and steel. The screw machine length body provides greater rigidity than jobber-length bits, reducing deflection in short-hole applications on CNC machining centers, drill presses, and manual mills. The straight-cylindrical shank seats directly in standard collets and drill chucks without adapters. At a flute-to-diameter ratio of 3xD, it handles shallow-to-moderate depth holes where chip packing is a concern. The tight diameter tolerance of plus 0.0000 to minus 0.0005 inches supports hole quality in precision assemblies.

Key Features

• Solid carbide construction for rigidity and heat resistance in hard-metal drilling
• 135-degree split point with web thinning reduces entry thrust and self-centers on the workpiece
• Slow spiral helical flute geometry promotes chip clearance in gummy and hard materials
• Coated finish extends cutting life and reduces built-up edge on stainless and cast iron
• Straight-cylindrical shank fits standard collets and chucks without modification
• Diameter tolerance of plus 0.0000 to minus 0.0005 inches supports tight-tolerance hole requirements

Compatibility

Designed for use in cast iron, non-ferrous metal, stainless steel, and steel workpieces. Fits standard drill chucks and collet systems accepting a 0.0145-inch straight-cylindrical shank. Compatible with CNC machining centers, drill presses, and manual milling machines equipped for small-diameter tooling.

Installation Notes

This bit is installed by machinists and precision metalworking technicians. Ensure the machine spindle and workpiece are fully secured before engaging the cutter. Use appropriate cutting fluid or coolant recommended for the workpiece material, particularly when drilling stainless steel or cast iron, to prevent premature tool wear. Inspect the cutting edges for chipping before each use, as solid carbide is brittle and susceptible to damage from interrupted cuts or improper handling.
