Eagle Cutting Tool 1090-044-I Hss Drill Bit 11/16 in

Product Description

The EAGLE CUTTING TOOL 1090-044-I is an 11/16-inch high speed steel (HSS) slow spiral drill bit with a 1/2-inch reduced shank, designed for metal drilling applications in trade and industrial settings. The slow spiral (low helix) flute geometry reduces chip packing and heat buildup when drilling deep holes or working with soft, gummy materials such as aluminum, copper, and soft steel. At 0.69 pounds, the bit is built for use in standard drill presses, magnetic drills, and heavy-duty hand drills equipped with a 1/2-inch chuck. Machinists, pipefitters, ironworkers, and maintenance mechanics are the primary users of this type of tooling.

This drill bit is suited for through-hole and clearance-hole work in metal fabrication, structural steel, HVAC ductwork framing, and mechanical maintenance environments. The 1/2-inch shank allows it to seat in standard 1/2-inch drill press chucks and magnetic base drills without a reduction sleeve. It is well matched for production drilling where a slow helix helps maintain chip clearance and cutting efficiency on softer or laminated metals.

Key Features

• 11/16-inch cutting diameter for large clearance and through holes in metal stock
• High speed steel construction resists heat and maintains edge hardness during extended use
• Slow spiral flute design reduces chip packing in soft and gummy metals
• 1/2-inch reduced shank fits standard drill press and magnetic drill chucks directly
• Minimum order quantity of 1 unit allows single-piece purchase

Compatibility

Designed as an OEM-style replacement or direct-use drill bit compatible with any drill press, magnetic drill, or heavy-duty hand drill fitted with a 1/2-inch chuck capacity.

Installation Notes

Installation and use should be performed by qualified machinists, pipefitters, or maintenance mechanics familiar with metal drilling practices. Always secure the workpiece firmly before drilling and ensure the bit is fully seated and tightened in the chuck before operation. Use appropriate cutting fluid or coolant when drilling ferrous metals to extend bit life and reduce heat buildup. Inspect the cutting edges for wear or damage before each use and replace if chipping or dullness is present.
