Eagle Cutting Tool SC404-128-D Cobalt Stub Drill Size 28

Product Description

The EAGLE CUTTING TOOL SC404-128-D is a Number 28 cobalt stub drill manufactured in the USA. Stub-length drills feature a shortened flute and overall length compared to jobber-length bits, which increases rigidity and reduces deflection when drilling in tight clearance areas or on hard materials. The cobalt construction provides elevated heat resistance and hardness retention, making this drill well suited for ferrous metals, stainless steel, cast iron, and other tough materials. This bit is a standard tool-crib item for machinists, maintenance technicians, pipefitters, and HVAC and plumbing professionals who drill through metal in the field or at the bench.

The SC404-128-D is appropriate for use in hand-held power drills, drill presses, and CNC machine tool applications wherever a Number 28 diameter hole is required. Its stub-length geometry makes it especially practical when working in confined spaces, on sheet metal panels, electrical enclosures, or mechanical equipment frames where a full-length jobber drill would flex or chatter. Domestic manufacture indicates conformance to recognized US tooling standards for geometry and metallurgy.

Key Features

• Cobalt alloy steel construction for superior heat resistance and edge retention on hard metals
• Stub-length design increases rigidity and reduces bit deflection in tight or confined drilling situations
• Number 28 drill size for precise fractional and wire-gauge hole requirements
• USA manufactured to standard tooling geometry specifications
• Minimum order quantity of 1 for flexible procurement

Compatibility

Designed as a direct-fit Number 28 stub-length drill for use in standard 3-jaw drill chucks on hand drills, drill presses, and compatible machining equipment. No specific OEM system compatibility was provided in the product data.

Installation Notes

Secure the drill shank fully in a properly tightened chuck before operation. Always wear appropriate eye protection when drilling metal. Use cutting fluid or coolant on ferrous and stainless materials to extend tool life and improve hole quality. De-energize or lock out any equipment being drilled on before commencing work, per applicable OSHA lockout/tagout procedures.
