Eagle Cutting Tool SC404-105-D Cobalt Stub Drill 5 Piece

Product Description

The EAGLE CUTTING TOOL SC404-105-D is a cobalt stub drill, sold in a 5-piece set and manufactured in the USA. Stub drills feature a shortened flute length compared to jobber-length bits, which increases rigidity and reduces deflection when drilling in confined spaces or hard materials. The cobalt construction improves heat resistance and edge retention, making these bits well suited for drilling into steel, stainless steel, cast iron, and other tough alloys. Licensed trades and industrial users rely on this style of bit where space is limited or where added stiffness is required to maintain hole accuracy.

This stub drill set is appropriate for metalworking applications across HVAC, plumbing, electrical, and general mechanical trades. The reduced-length design is a common choice when drilling through thick fastener flanges, structural steel, or close-clearance mounting locations where a standard-length bit would flex or chatter. These bits are used in both hand-held drill motors and drill press setups.

Key Features

• Cobalt construction provides elevated heat resistance and edge retention in hard metals
• Stub length design increases rigidity and reduces deflection in tight spaces
• USA manufactured for consistent dimensional tolerances
• 5-piece set allows for redundancy and continued work when one bit reaches end of service life
• Suitable for drilling steel, stainless steel, cast iron, and hard alloys

Compatibility

Designed as a general-purpose OEM-style stub drill replacement suitable for use in standard drill chucks and drill press setups commonly found in HVAC, plumbing, and electrical trade applications.

Installation Notes

Cobalt stub drills are installed and used by licensed tradespeople and machinists following standard metal-drilling practices. Secure the workpiece firmly before drilling to prevent movement and maintain hole accuracy. Use appropriate cutting fluid or lubricant when drilling hard metals to extend bit life and reduce heat buildup. Inspect each bit for wear or chipping before use and replace damaged bits immediately to avoid workpiece damage or injury.
