Eagle Cutting Tool SC404-109-D Cobalt Stub Drill Size 9

Product Description

The EAGLE CUTTING TOOL SC404-109-D is a Size 9 cobalt stub drill manufactured in the USA. Stub drills — also called screw machine length drills — feature a shorter flute and overall length than jobber drills, providing greater rigidity and reduced deflection in high-torque drilling applications. The cobalt construction allows the drill to maintain cutting hardness at elevated temperatures, making it well suited for drilling through tough ferrous metals, stainless steel, and other hard alloys. This drill is used by machinists, pipefitters, and mechanical contractors who require precise, repeatable hole sizing in demanding materials.

This drill fits standard drilling applications in industrial, commercial, and trade settings where a rigid, short-length drill is preferred over a standard jobber length. Typical scenarios include drilling in tight clearance areas, use in drill presses, CNC turret machines, and screw machines. The stub length format reduces vibration and improves hole accuracy, particularly in hard or abrasive materials where a longer drill would flex or wander.

Key Features

• Cobalt construction retains cutting edge hardness under high heat
• Stub (screw machine) length provides increased rigidity and reduced deflection
• USA manufactured
• Size 9 wire gauge designation for precise hole sizing
• Compatible with standard drill chucks and collet systems

Compatibility

Designed as an OEM-style replacement or direct-use stub drill for standard drill press, screw machine, and hand-held drilling equipment accepting wire gauge Size 9 drill bits.

Installation Notes

Installation of this drill should be performed by qualified machinists or trade professionals familiar with rotating cutting tools. Ensure the drilling machine is fully powered down and the chuck is secure before inserting or removing the drill bit. Always wear appropriate eye protection and secure workpieces properly before drilling. Follow applicable shop safety codes and machine manufacturer guidelines for speed and feed settings appropriate to the material being drilled.
