Eagle Cutting Tool SC400-009-D Cobalt Stub Drill 9/64 in

Product Description

The EAGLE CUTTING TOOL SC400-009-D is a 9/64-inch cobalt stub-length drill bit ground with a 135-degree split point. The stub-length body is shorter than a standard jobber drill, which reduces deflection and improves rigidity when drilling in tight spaces or on harder work materials. The 135-degree split point geometry starts on contact without a center punch, reducing walking on smooth or curved surfaces. Manufactured in the USA, this bit is suited for production drilling environments where heat resistance and edge retention are priorities. Machinists, fabricators, and maintenance technicians working with stainless steel, hardened alloys, and high-strength metals reach for cobalt-grade tooling for extended tool life under those conditions.

The SC400-009-D fits 9/64-inch drilling applications in machine shops, maintenance facilities, and metal fabrication shops. It is designed for use in drill presses, CNC machining centers, and hand-held electric drills with appropriate speed and feed settings for cobalt tooling. The stub-length format is particularly well-suited for sheet metal work, close-tolerance drilling near fixtures, and applications where a standard jobber-length bit would flex or chatter. It is an appropriate choice for professionals drilling carbon steel, stainless steel, cast iron, and similar ferrous materials.

Key Features

• 9/64-inch diameter cobalt construction for heat and wear resistance on hard materials
• 135-degree split point starts on contact without center punching
• Stub-length body reduces deflection and increases rigidity over jobber-length bits
• USA manufactured for consistent geometry and quality control
• Suitable for stainless steel, alloy steel, cast iron, and other ferrous metals

Compatibility

Designed as a direct-fit 9/64-inch stub-length drill bit for use in any standard 3/8-inch or larger drill chuck accepting fractional-inch tooling.

Installation Notes

Secure the bit firmly in the chuck before operation and verify runout is within acceptable tolerance for the application. Use cutting fluid or coolant appropriate for cobalt tooling when drilling stainless or hardened alloys to maximize tool life. Set spindle speed according to published surface-footage recommendations for cobalt bits at this diameter on the target material. Inspect the cutting edges before each use and replace the bit if chipping or heat discoloration is present at the point.
