Eagle Cutting Tool SC400-018-I Cobalt Stub Drill 9/32

Product Description

The EAGLE CUTTING TOOL SC400-018-I is a cobalt stub drill bit sized at 9/32 inch, designed for demanding drilling applications where standard high-speed steel bits fall short. Cobalt construction provides increased heat resistance and hardness, making this drill suitable for cutting through tough materials such as stainless steel, cast iron, and hardened alloys. The stub-length body offers greater rigidity compared to jobber-length bits, reducing deflection and improving hole accuracy in tight or restricted spaces. Machinists, fabricators, and maintenance technicians commonly use stub drills where bit flex is a concern or where limited clearance requires a shorter tool profile.

This 9/32-inch cobalt stub drill is appropriate for use in drill presses, CNC machines, and hand-held power drills across both shop and field environments. It suits general metalworking, maintenance repair operations, and production drilling in industrial and commercial settings. The stub-length geometry is a standard choice when working in fixtures or when hole positioning requires a stiffer, more controlled cutting tool.

Key Features

• Cobalt construction for improved heat resistance and extended tool life in hard materials
• Stub-length body provides greater rigidity and reduced deflection versus jobber-length bits
• 9/32-inch diameter for precise, consistent hole sizing
• Suitable for stainless steel, cast iron, hardened alloys, and similar difficult-to-machine materials
• Minimum order quantity of 1 unit

Compatibility

Designed as an OEM-style replacement or direct-use stub drill bit compatible with standard drill chucks and toolholding systems accepting 9/32-inch shank diameters in drill press, CNC, and handheld power drill applications.

Installation Notes

This drill bit is installed and operated by machinists, fabricators, or maintenance technicians familiar with metalworking equipment. Ensure the drill chuck or collet is properly secured before operation and that the workpiece is clamped firmly to prevent movement. Use appropriate cutting fluid or coolant when drilling hard metals to manage heat buildup and extend bit life. Follow applicable shop safety practices and equipment manufacturer guidelines for speed and feed rates.
