M.a. Ford 20514950 Size 25 Carbide Screw Machine Drill Bit

Product Description

The M.A. FORD 20514950 is a solid carbide screw machine length drill bit in wire gauge Size 25, equivalent to 0.1495 inches in diameter. It features a 135-degree split point that reduces walking on entry and requires no center punch on most materials. The slow spiral flute geometry is suited for high-feed, short-hole drilling applications where rigidity and chip evacuation in tough materials are priorities. The bright uncoated finish makes it a versatile choice across a wide range of workpiece materials. At 2.0625 inches overall length, this is a compact, stub-style bit intended for use in production drilling, CNC machining, and screw machine operations where tool runout and deflection must be minimized.

This drill bit is designed for drilling steel, stainless steel, cast iron, aluminum and non-ferrous metals, high-temperature alloys, and hardened materials. Its short overall length and straight cylindrical shank make it well suited for use in drill presses, CNC machining centers, turret lathes, and automatic screw machines. The 3xD flute-to-diameter ratio and web-thinned point reduce thrust requirements in hard and abrasive materials, making it a practical choice for production shops and tool rooms working with difficult-to-machine metals.

Key Features

• Solid carbide construction provides rigidity and wear resistance in hard and abrasive workpiece materials
• 135-degree split point reduces entry thrust and eliminates the need for center punching on most setups
• Slow spiral flute design promotes controlled chip evacuation in short-hole, high-feed drilling
• Web-thinned point lowers cutting forces when drilling stainless steel, cast iron, and high-temp alloys
• Straight cylindrical shank at 0.1495 inches diameter fits standard drill chucks and collet systems
• Bright uncoated finish maintains dimensional accuracy and works across ferrous and non-ferrous materials without coating interference

Compatibility

Designed as an OEM-style screw machine length drill bit suitable for use in drill presses, CNC machining centers, turret lathes, and automatic screw machine setups requiring a wire gauge Size 25 straight-shank carbide drill.

Installation Notes

Installation and operation should be performed by a qualified machinist or tool room technician familiar with carbide tooling. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing or seating the bit in the chuck or collet. Solid carbide tooling is brittle and should not be subjected to side loads, interrupted cuts beyond design parameters, or improper runout in the holder. Always verify shank diameter tolerance compatibility with the collet or chuck before use to prevent premature tool failure.
