YG-1 DTX414232 Screw Machine Drill Bit Solid Carbide Tialn

Product Description

The YG-1 DTX414232 is a screw machine length (stub length) drill bit engineered for high-performance drilling in metal fabrication, machining, and maintenance applications. Built from solid carbide, it delivers the rigidity and wear resistance needed for demanding materials. The TiAlN coating adds thermal protection, extending tool life in dry or high-speed cutting conditions. With a 2-flute geometry and a 140-degree split-point tip, it enters the workpiece cleanly and reduces walking without a center punch. This bit is sized for use in CNC machining centers, drill presses, and hand-held power tools where a compact overall length improves rigidity and reduces deflection.

This drill bit is suited for precision hole-making in ferrous metals, hardened steels, cast iron, stainless steel, and similar materials encountered in industrial and trade settings. The stub length profile makes it a preferred choice when working in confined spaces or when maximum rigidity is required to maintain hole straightness and diameter tolerance. Machinists, tool-and-die workers, and maintenance technicians commonly use this style bit in production and repair environments.

Key Features

• Solid carbide construction provides superior hardness and wear resistance compared to high-speed steel
• TiAlN coating improves heat resistance and extends tool life in high-speed or dry cutting operations
• 140-degree drill point angle reduces thrust force and self-centers on flat or curved surfaces
• 2-flute regular spiral geometry promotes efficient chip evacuation during through-hole drilling
• Straight shank is compatible with standard drill chucks and collet holders
• Screw machine length (stub) body minimizes deflection and improves hole accuracy in tight setups

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide stub drill for use in standard drill chucks, ER collet systems, and keyless chucks accepting straight-shank tooling across CNC and manual drilling equipment.

Installation Notes

Installation and use should be performed by a qualified machinist or tooling professional familiar with cutting speeds, feeds, and proper tool holding practices. Ensure the drill press, CNC spindle, or power tool is fully stopped and isolated from power before changing tooling. Secure the straight shank firmly in the chuck or collet to the full recommended engagement depth to prevent pullout and runout. Do not use coolant-through fixtures with this bit, as it does not support internal coolant delivery.
