Eagle Cutting Tool C1090-048-I Cobalt Drill Bit 3/4 in

Product Description

The EAGLE CUTTING TOOL C1090-048-I is a 3/4-inch cobalt screw machine (stub length) drill bit with a 1/2-inch reduced shank. Cobalt construction delivers increased heat resistance and hardness compared to standard high-speed steel, making this bit suited for drilling stainless steel, cast iron, hardened alloys, and other tough materials. The stub-length body provides added rigidity and reduced deflection in demanding production and service environments. This bit is installed by machinists, maintenance technicians, and trade professionals working with drill presses, CNC equipment, and heavy-duty handheld drills.

This drill bit is well suited for metal fabrication shops, industrial maintenance, HVAC equipment manufacturing, and mechanical contracting work where hard or abrasive base metals are encountered. The 1/2-inch shank allows it to seat in standard 1/2-inch chuck equipment without a reducer. The screw machine length profile is commonly chosen when a shorter, stiffer drill is preferred over a jobber-length bit in tight clearance or high-feed applications.

Key Features

• Cobalt alloy construction resists heat buildup during aggressive drilling cycles
• 3/4-inch cutting diameter in a stub screw machine length for added rigidity
• 1/2-inch reduced shank fits standard half-inch chucks without an adapter
• Suitable for stainless steel, cast iron, hardened alloys, and hard non-ferrous metals
• Minimum order quantity of 1 unit for flexible procurement

Compatibility

Designed as an OEM-style replacement or direct-use screw machine drill bit for any drill press, mill, CNC spindle, or handheld drill accepting a 1/2-inch round shank.

Installation Notes

Installation is performed by machinists or qualified mechanical technicians. Secure the shank fully in the chuck and verify it is tightened before operation. Always wear appropriate eye and hand protection when operating drilling equipment. Follow applicable OSHA machine guarding and tool-change lockout/tagout procedures when mounting or removing bits in powered equipment.
