M.a. Ford. 20623440 Carbide Screw Machine Drill Bit 15/64

Product Description

The M.A. FORD. 20623440 is a solid carbide screw machine length drill bit designed for precision drilling in demanding metalworking applications. With a 15/64 inch (0.2344 inch decimal) diameter and a 118-degree faceted point angle, it delivers clean, accurate entry in cast iron, stainless steel, non-ferrous metals, and carbon steel. The bright, uncoated finish suits dry cutting or standard coolant-applied operations. At 2.5 inches overall length with a 1-inch flute length, this short-length geometry provides increased rigidity and reduced deflection versus jobber-length bits. Licensed machinists, tool and die technicians, and precision fabricators are the primary users.

This drill bit is built for short-hole drilling operations where rigidity and concentricity are critical. The screw machine length format makes it well-suited for drill press work, CNC machining centers, turret lathes, and manual mill setups where workpiece clearance is tight. The 3xD flute-to-diameter ratio supports chip evacuation in shallow-to-moderate depth holes. Applications include production drilling in cast iron components, stainless steel fabrication, and non-ferrous structural parts. The straight-cylindrical shank seats directly in standard ER collets, drill chucks, and toolholders without modification.

Key Features

• Solid carbide construction for high rigidity and heat resistance in ferrous and non-ferrous materials
• 118-degree faceted drill point with web thinning for reduced thrust and cleaner hole entry
• Bright/uncoated finish compatible with dry cutting and standard flood coolant
• Right-hand spiral flute geometry promotes consistent chip evacuation
• Straight-cylindrical shank fits standard drill chucks and ER collets
• Short screw machine length reduces deflection and improves hole location accuracy

Compatibility

Designed as an OEM-style replacement and standard tooling option for applications requiring a 15/64 inch diameter screw machine length drill bit in solid carbide; compatible with any spindle or toolholder accepting a 0.2344 inch straight-cylindrical shank.

Installation Notes

Installation of this drill bit should be performed by qualified machinists or toolroom technicians familiar with carbide tooling procedures. Ensure the spindle is fully powered down and the machine is in a locked-out state before changing tooling. Carbide tooling is brittle — avoid side-loading, interrupted cuts beyond the material rating, or excessive feed rates that can cause chipping or fracture. Verify shank seating depth and runout with a dial indicator before beginning production cuts.
