Eagle Cutting Tool C304-129-D Cobalt Jobber Drill No 29

Product Description

The EAGLE CUTTING TOOL C304-129-D is a Number 29 cobalt jobber-length drill bit manufactured in the USA. Cobalt construction gives this bit increased heat resistance and edge retention compared to standard high-speed steel, making it well suited for drilling hard metals, stainless steel, cast iron, and other difficult materials. The jobber-length flute profile balances reach and rigidity for general-purpose drilling in production and maintenance environments. This bit is a standard addition to any trade toolbox where consistent hole quality and bit longevity are required.

This drill bit is used across a wide range of trade applications including HVAC, plumbing, electrical, and general mechanical work wherever Number 29 wire-gauge holes are needed. It performs in both handheld drill drivers and drill press setups. The cobalt alloy construction makes it a go-to choice when cutting through harder base metals or when work involves elevated friction and heat buildup at the cutting face.

Key Features

• Number 29 wire-gauge diameter for precise hole sizing
• Cobalt alloy construction for superior heat and wear resistance
• Jobber-length flute for balanced reach and rigidity
• USA manufactured for consistent dimensional tolerances
• Suitable for drilling hard metals, stainless steel, and cast iron

Compatibility

Designed as a standard Number 29 wire-gauge jobber drill bit compatible with conventional drill chucks accepting the corresponding shank diameter, suitable for use in handheld drills and drill press applications across trade and industrial settings.

Installation Notes

This bit is installed and used by licensed tradespeople and experienced mechanics in standard drill chucks or drill press collets. Secure the bit fully in the chuck before operation and confirm the workpiece is clamped or fixtured to prevent movement. When drilling hard or heat-sensitive materials, use appropriate cutting fluid to extend bit life and maintain hole quality. Inspect the cutting edges before each use and replace the bit if chipping or dulling is observed.
