Eagle Cutting Tool C300-004-D Cobalt Jobber Drill 1/16

Product Description

The EAGLE CUTTING TOOL C300-004-D is a 1/16 inch cobalt jobber-length drill bit manufactured in the USA. Cobalt construction provides superior heat resistance and hardness compared to standard high-speed steel, making this bit well suited for drilling hard ferrous metals, stainless steel, cast iron, and other tough materials encountered in trade and industrial work. At 0.5 pounds, it is a compact, single-bit tool sized for precision work in tight spaces. Electricians, plumbers, HVAC technicians, and general tradespeople use this type of bit when standard HSS bits fail to hold an edge.

This cobalt jobber drill is appropriate for use in residential and commercial installation and service work where small-diameter, high-precision holes are required. Common applications include drilling pilot holes in sheet metal, structural steel, stainless enclosures, and similar hard substrates. The jobber-length geometry balances reach and rigidity for general-purpose drilling tasks. It is intended for use in standard drill chucks and rotary tools that accept 1/16 inch shank sizes.

Key Features

• Cobalt steel construction for enhanced hardness and heat resistance in hard-metal drilling
• 1/16 inch diameter for small-diameter, precision hole work
• Jobber-length geometry provides balanced reach and rigidity
• Manufactured in the USA
• Minimum order quantity of 1, suitable for single-unit procurement

Compatibility

Designed as a standard jobber-length drill bit compatible with any drill chuck or rotary tool accepting a 1/16 inch shank.

Installation Notes

This bit is installed and used by electricians, HVAC technicians, plumbers, and general trade professionals. Secure the bit firmly in the chuck before use and verify chuck key is removed prior to operation. Use appropriate cutting fluid or lubricant when drilling hard metals to extend bit life and reduce heat buildup. Always wear eye protection when drilling metal substrates.
