Eagle Cutting Tool 1090-132-I Hss Slow Spiral Drill Bit

Product Description

The EAGLE CUTTING TOOL 1090-132-I is a high speed steel (HSS) slow spiral drill bit designed for drilling operations that require reduced chip evacuation speed and controlled cutting action. The 1-1/2 inch cutting diameter paired with a 1/2 inch reduced shank makes this bit compatible with standard 1/2 inch chuck capacity drilling equipment. Slow spiral geometry lowers the helix angle compared to standard twist drills, which helps prevent grab and reduces heat buildup when working through softer or gummy materials. This is an import-grade bit suited for production and service applications where cost-effective tooling is a priority.

This drill bit is used in metal fabrication, HVAC sheet metal work, plumbing rough-in, and general construction drilling where a large-diameter hole is required. The reduced 1/2 inch shank allows use in standard drill presses and heavy-duty hand drills without requiring a larger chuck. Typical applications include drilling through steel plate, copper, aluminum, and similar materials where a slow spiral profile helps maintain hole accuracy and reduce chatter. Licensed tradespeople and shop machinists are the primary installers of tooling in this category.

Key Features

• 1-1/2 inch cutting diameter for large-bore drilling applications
• 1/2 inch reduced shank fits standard 1/2 inch drill chucks
• High speed steel construction provides hardness and heat resistance during metal cutting
• Slow spiral flute geometry reduces grab and controls chip flow in soft metals and plastics
• Import-grade pricing supports high-volume or disposable tooling programs

Compatibility

Designed as an OEM-style replacement or service drill bit for use in any drill press or hand drill equipped with a 1/2 inch or larger chuck capacity.

Installation Notes

Secure the 1/2 inch shank fully into the chuck and tighten with a chuck key before operation. Use appropriate cutting fluid or lubricant when drilling ferrous metals to extend bit life and maintain hole quality. Ensure the workpiece is clamped securely before beginning the cut to prevent rotation and injury. Inspect the cutting edges before each use and replace if chipping or dulling is observed.
