Eagle Cutting Tool S404-108-D Hss Stub Drill Bit

Product Description

The EAGLE CUTTING TOOL S404-108-D is a high-speed steel (HSS) stub-length drill bit featuring a 135-degree split point geometry. Stub-length drills, sometimes called screw-machine-length drills, have a shorter flute and overall length than jobber bits, which increases rigidity and reduces deflection during entry. The 135-degree split point allows the bit to self-center on the workpiece without a center punch, reducing walking on hard or smooth surfaces. This bit is manufactured in the USA and is suited for use in production drilling, CNC, and handheld power tool applications across metal fabrication and mechanical trades.

This stub drill is designed for drilling ferrous and non-ferrous metals, plastics, and similar materials where a rigid, low-deflection bit is preferred. The shorter body makes it well-suited for tight-clearance drilling situations, close-tolerance work, and high-cycle production environments. Machinists, maintenance technicians, and metalworking professionals will find this bit appropriate for use in drill presses, CNC machining centers, and portable electric drills.

Key Features

• 135-degree split point self-centers on contact, reducing the need for a center punch
• Stub-length body provides increased rigidity and minimized deflection compared to jobber-length bits
• High-speed steel construction handles the heat and stress of metal drilling applications
• Manufactured in the USA
• Minimum order quantity of 1 unit

Compatibility

Designed as an OEM-style replacement or direct-use stub drill bit compatible with standard drill chucks accepting the corresponding shank diameter for this bit size.

Installation Notes

Installation should be performed by machinists or qualified tradespeople familiar with drill press and power tool operation. Secure the bit firmly in the chuck before use and verify the chuck key is removed before powering the tool. Use appropriate cutting fluid when drilling ferrous metals to extend bit life and manage heat buildup. Always wear appropriate eye protection and secure the workpiece to prevent movement during drilling.
