Eagle Cutting Tool S404-105-D Hss Stub Drill 135 Split Point

Product Description

The EAGLE CUTTING TOOL S404-105-D is a high-speed steel stub drill bit featuring a 135-degree split point geometry. Stub drills are shorter than standard jobber-length bits, which increases rigidity and reduces deflection during drilling operations. The 135-degree split point eliminates the need for a center punch on most materials and allows the bit to self-center on contact. This drill is manufactured in the USA and is suited for machinists, tool and die techs, maintenance mechanics, and other trade professionals who require accurate, controlled drilling in tight or constrained workspaces.

The S404-105-D is appropriate for use on ferrous metals, mild steel, aluminum, and similar machinable materials in both manual and CNC drilling applications. Its abbreviated flute length makes it a preferred choice when working in shallow-clearance setups, on drill presses, or in applications where bit flex would compromise hole accuracy. The stub length profile also suits fixture drilling and repetitive production work where bit stability is critical.

Key Features

• High-speed steel (HSS) construction for durability across common metalworking applications
• 135-degree split point geometry for self-centering and reduced thrust force
• Stub length body increases rigidity and minimizes deflection
• USA manufactured
• Minimum order quantity of 1 unit

Compatibility

Designed as a standard HSS stub drill bit suitable for use in hand drills, drill presses, and CNC machining centers accepting compatible chuck sizes for this bit diameter.

Installation Notes

Installation and use of this drill bit should follow standard machining safety practices. Secure the bit firmly in the chuck before operation and verify chuck key removal prior to powering the tool. Use appropriate cutting fluid or lubricant when drilling ferrous metals to extend bit life and improve hole quality. Wear approved eye protection at all times during drilling operations.
