Eagle Cutting Tool C1080-059-D Cobalt Drill Bit 59/64

Product Description

The EAGLE CUTTING TOOL C1080-059-D is a 59/64-inch cobalt screw machine (stub length) drill bit with a 1/2-inch straight shank. Cobalt-grade high-speed steel construction delivers increased heat resistance and edge retention compared to standard HSS bits, making this drill well suited for harder materials including stainless steel, cast iron, and high-temp alloys. The stub-length body provides added rigidity and reduced deflection during drilling, which is critical when holding tight tolerances in production or maintenance machining environments. This bit is manufactured in the USA.

The C1080-059-D is intended for use in machine shops, industrial maintenance settings, and fabrication environments where a shorter, stiffer drill profile is preferred over a jobber-length bit. It is a practical choice for machinists and tooling specialists drilling through hard ferrous and non-ferrous metals in drill presses, milling machines, and CNC equipment. The 1/2-inch shank accommodates standard half-inch drill chucks and collet holders commonly found in production tooling setups.

Key Features

• 59/64-inch cobalt high-speed steel cutting diameter for hard-material drilling applications
• Stub screw machine length body increases rigidity and minimizes deflection
• 1/2-inch straight shank fits standard chucks and collet holders
• Cobalt alloy construction resists heat buildup and extends tool life on difficult materials
• Made in the USA

Compatibility

Designed as an OEM-style replacement or direct tooling selection for drill presses, milling machines, and CNC equipment fitted with 1/2-inch chuck or collet capacity.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians familiar with cutting tool safety. Ensure the drill chuck or collet is fully tightened and the workpiece is securely fixtured before beginning any drilling operation. Use appropriate cutting fluid or coolant for the material being drilled to maximize tool life. Always wear appropriate personal protective equipment including eye protection when operating drilling equipment.
