Eagle Cutting Tool SC400-016-I Cobalt Stub Drill 1/4 in

Product Description

The EAGLE CUTTING TOOL SC400-016-I is a 1/4-inch cobalt stub drill designed for fast, accurate hole-making in tough materials. The 135-degree split point geometry reduces walking on entry, eliminates the need for a center punch in most applications, and cuts more aggressively than a standard 118-degree point. The stub-length body provides added rigidity compared to jobber-length drills, making it well suited for applications where deflection and chatter are a concern. This drill is sized to imperial specifications and is intended for use by machinists, pipefitters, electricians, and general-trade mechanics who drill into hard or work-hardening metals regularly.

This drill is used in residential and commercial trade settings wherever metal drilling is required — conduit work, pipe fitting, structural steel, stainless fabrication, and general maintenance. The cobalt construction handles high heat buildup during prolonged cuts, making it a practical choice for drilling harder alloys, stainless steel, and cast iron without premature edge failure. The stub-length format is particularly common in confined spaces where a full-length jobber drill would be difficult to handle.

Key Features

• 135-degree split point reduces drill walking and minimizes center-punch requirements
• Cobalt construction resists heat and wear when drilling hard or abrasive metals
• Stub-length body increases rigidity and reduces deflection during drilling
• 1/4-inch imperial diameter — compatible with standard three-jaw drill chucks and quick-change systems
• Suited for stainless steel, hardened alloys, cast iron, and work-hardening materials

Compatibility

Designed as an OEM-style replacement or direct upgrade for 1/4-inch imperial stub drills used in standard drill chucks, drill presses, and magnetic base drills across commercial and industrial trade applications.

Installation Notes

Install in a properly rated drill press, hand drill, or magnetic base drill with a compatible three-jaw or quick-change chuck rated for the intended speed and material. Always set spindle RPM appropriate to the material being drilled — cobalt tooling tolerates higher heat than high-speed steel but still benefits from correct speeds and cutting fluid on harder alloys. Secure the workpiece firmly before drilling to prevent rotation or movement. Wear appropriate eye protection and follow applicable shop safety standards when operating rotary cutting tools.
