M.a. Ford 20612850 Carbide Screw Machine Drill 0.1285 in

Product Description

The M.A. FORD 20612850 is a solid carbide screw machine length drill bit with a 0.1285-inch diameter, equivalent to wire gauge size 30. Designed for short-reach, high-precision drilling, it features a 118-degree faceted point angle and a regular spiral flute configuration for efficient chip evacuation. The web-thinned design reduces thrust and improves penetration in hard materials. This bit suits machinists, tool-and-die technicians, and production drilling operations where dimensional accuracy and tool life in demanding materials are priorities. It ships bright and uncoated, ready for immediate use.

This drill bit is suited for drilling cast iron, non-ferrous metals, stainless steel, and steel in production and job-shop environments. The screw machine length profile keeps the tool compact and rigid, making it well-matched for CNC machining centers, drill presses, and turret lathes where short tool overhang reduces deflection and improves hole quality in close-tolerance applications.

Key Features

• Solid carbide construction for extended tool life in hard and abrasive workpiece materials
• 118-degree faceted point angle with web thinning for reduced entry thrust
• Regular spiral flute geometry promotes consistent chip evacuation
• Straight-cylindrical shank compatible with standard drill chucks and collets
• Right-hand cut with parallel web configuration for dimensional stability
• Diameter tolerance held to +0.0000 to -0.0005 inches for precise hole sizing

Compatibility

Designed as an OEM-style screw machine length drill bit in M.A. FORD Series 206, suited for use in standard drill chucks and collet systems accepting a 0.1285-inch straight-cylindrical shank across CNC and manual machine tool platforms.

Installation Notes

Installation is performed by machinists or tool-room technicians using standard toolholding equipment. Ensure the shank is fully seated and the chuck or collet is properly torqued before operation. Verify spindle speed and feed rate are appropriate for the workpiece material and tool diameter prior to engaging the cut. Coolant-through is not supported on this tool; apply external coolant or cutting fluid as required by the workpiece material and shop practice.
