Eagle Cutting Tool 1090D-045-I Drill Bit 45/64 in

Product Description

The EAGLE CUTTING TOOL 1090D-045-I is a screw machine length drill bit designed for high-production drilling applications where rigidity and reduced deflection are priorities. The 45/64 inch cutting diameter pairs with a 1/2 inch straight shank, making it compatible with standard drill chucks and tool holders commonly found in machine shop and production environments. Its shorter flute length compared to jobber drills provides greater stability in deeper setups and reduces chatter on harder materials. Machinists, tool and die workers, and maintenance professionals use this bit for precise hole-making in metal and similar materials.

This drill bit is suited for use in drill presses, CNC machining centers, and manual milling machines in light industrial and production shop settings. The screw machine (stub length) geometry is the preferred choice when drilling in confined spaces or when the work setup demands less tool overhang. The import designation reflects the manufacturing origin of this bit.

Key Features

• 45/64 inch cutting diameter for precise hole sizing
• 1/2 inch straight shank fits standard chucks and collet holders
• Screw machine (stub) length reduces deflection and improves hole accuracy
• Shorter flute length provides added rigidity in production drilling setups

Compatibility

Designed as an OEM-style replacement or direct-use screw machine drill bit for standard 1/2 inch chuck and collet tool holders used in drill press, manual mill, and CNC drilling applications.

Installation Notes

Installation of this drill bit should be performed by a qualified machinist or tool operator. Ensure the machine spindle is fully powered down and at rest before changing tooling. Secure the shank firmly in the chuck or collet to the full recommended engagement depth to prevent slippage during operation. Follow applicable shop safety standards and wear appropriate eye and hand protection when handling and operating cutting tools.
