Eagle Cutting Tool C300-032-D Cobalt Jobber Drill 1/2 in

Product Description

The EAGLE CUTTING TOOL C300-032-D is a 1/2-inch cobalt jobber-length drill bit manufactured in the USA. Cobalt construction gives this bit the hardness and heat resistance needed to cut through tough materials including stainless steel, cast iron, high-nickel alloys, and hardened steels. The jobber-length geometry provides a practical balance of reach and rigidity for general-purpose drilling in trade and industrial environments. Electricians, plumbers, HVAC technicians, and pipefitters rely on cobalt jobber drills for accurate, clean holes in metal framing, pipe, conduit, and structural members.

This drill bit is suited for hand-held drill presses, benchtop drill presses, and mag-base drills commonly used in commercial and industrial settings. Typical applications include drilling pilot holes in structural steel, creating penetrations in heavy-gauge sheet metal, and boring through cast or ductile iron fittings. The 1/2-inch diameter is a standard size widely used in mechanical, electrical, and plumbing trades for anchor holes, conduit knockouts, and pipe penetrations.

Key Features

• Cobalt steel construction for superior hardness and heat resistance in tough metal cutting
• 1/2-inch diameter in standard jobber length for versatile reach and rigidity
• Manufactured in the USA
• Suitable for stainless steel, cast iron, hardened steel, and high-temperature alloys
• Compatible with standard 1/2-inch drill chucks and mag-base drill setups

Compatibility

Designed as a standard 1/2-inch cobalt jobber drill for use in any drill press, magnetic drill, or hand drill equipped with a 1/2-inch or larger keyed or keyless chuck.

Installation Notes

A licensed tradesperson or qualified machinist should select appropriate cutting speeds and feeds based on the material being drilled. Always secure the workpiece firmly before drilling and use a center punch to prevent bit walking on metal surfaces. Apply cutting fluid when drilling stainless steel or other hard alloys to extend bit life and manage heat buildup. Wear appropriate PPE including eye protection when operating any rotary cutting tool.
