Eagle Cutting Tool 1090-036-I Hss Drill Bit 9/16 in

Product Description

The EAGLE CUTTING TOOL 1090-036-I is a 9/16-inch high-speed steel (HSS) slow-spiral drill bit with a 1/2-inch reduced shank, designed for precision drilling in metal fabrication, maintenance, and industrial applications. The slow-spiral (SD) flute geometry reduces chip buildup and heat generation when drilling through tough or gummy materials. At 0.69 pounds, the bit is built for use in standard 1/2-inch chuck drill presses, magnetic drills, and heavy-duty hand drills. HSS construction provides reliable hardness and wear resistance across a broad range of workpiece materials.

This drill bit is suited for machinists, maintenance technicians, pipefitters, and fabricators who need a larger-diameter bit for drilling structural steel, plate stock, pipe flanges, or similar materials. The 1/2-inch shank allows use in common 1/2-inch capacity chucks without requiring a specialty adapter, making it a practical choice for field and shop use alike.

Key Features

• 9/16-inch cutting diameter for larger-bore hole requirements
• High-speed steel (HSS) construction for durability and heat resistance
• Slow-spiral flute design reduces chip packing in tough or stringy materials
• 1/2-inch reduced shank fits standard 1/2-inch drill chucks
• Minimum order quantity of 1 — available as a single unit

Compatibility

Designed for use in any drill press, magnetic drill, or hand drill equipped with a standard 1/2-inch capacity chuck. Suitable for drilling ferrous metals, mild steel, and similar materials where a slow-spiral HSS bit is specified.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or trade professionals familiar with drilling operations. Secure the shank fully in the chuck and verify the bit is centered before beginning the cut. Always power down and de-energize the drill before changing bits. Use appropriate cutting fluid when drilling ferrous metals to extend bit life and reduce heat buildup.
