Eagle Cutting Tool S404-104-D Hss Stub Drill 135SP

Product Description

The EAGLE CUTTING TOOL S404-104-D is a high-speed steel (HSS) stub drill bit manufactured in the USA with a 135-degree split point geometry. Stub drills are shorter than jobber-length bits, which reduces deflection and increases rigidity during drilling operations. The 135-degree split point eliminates the need for a center punch by self-centering on contact, making it well suited for production and repetitive drilling tasks where accuracy and speed matter. This bit is designed for use by machinists, tool and die workers, and maintenance professionals working in metal fabrication and industrial environments.

The S404-104-D is suited for drilling into steel, cast iron, aluminum, and other common ferrous and non-ferrous metals. Its stub length makes it a preferred choice for drilling in confined spaces or when using a drill press, CNC machine, or turret lathe where a shorter tool overhang improves hole quality and reduces chatter. It is appropriate for both production shops and maintenance facilities.

Key Features

• 135-degree split point self-centers on contact, reducing walking and improving hole accuracy
• Stub length construction provides greater rigidity and reduced deflection compared to jobber-length bits
• High-speed steel (HSS) construction offers durability across a wide range of common metals
• Manufactured in the USA

Compatibility

Designed as an OEM-style replacement or standard substitute for HSS stub drill bits used in metal drilling applications across production and maintenance environments.

Installation Notes

This bit is installed by machinists and tool operators in drill presses, CNC machines, lathes, and hand drills using a standard drill chuck sized for the shank diameter. Ensure the machine is powered off and the chuck is fully tightened before operation. Use appropriate cutting fluid or coolant when drilling ferrous metals to extend bit life and maintain cut quality. Follow shop safety procedures and applicable OSHA guidelines when operating drilling equipment.
