Eagle Cutting Tool 1090-101-I Hss Drill Bit 1-1/64 in

Product Description

The EAGLE CUTTING TOOL 1090-101-I is a high-speed steel (HSS) twist drill bit ground to a 1-1/64 inch diameter with a 1/2 inch reduced shank. HSS construction provides the hardness and heat resistance needed for drilling through mild steel, cast iron, aluminum, wood, and plastics. The 1/2 inch shank allows this bit to seat securely in standard 1/2 inch drill chucks found on benchtop drill presses and heavy-duty hand drills. Machinists, pipefitters, electricians, and general fabricators reach for this size when drilling precise clearance or pilot holes in metal fabrication and maintenance work.

This drill bit is suited for light industrial, commercial, and trade shop applications where consistent hole geometry is required. The 1-1/64 inch diameter is a common size for clearance holes, pilot drilling before tapping, and deburring operations on ferrous and non-ferrous stock. It fits standard 1/2 inch chuck machinery without a sleeve adapter, making it a straightforward drop-in for shop use.

Compatibility

Designed for use in standard 1/2 inch keyed or keyless drill chucks on benchtop drill presses, magnetic drills, and hand-held drill motors commonly used in metal fabrication and trade service work.

Installation Notes

Install the bit fully into the drill chuck and tighten securely before operation. Ensure the workpiece is clamped or fixtured to prevent rotation during drilling. Use appropriate cutting fluid when drilling ferrous metals to reduce heat buildup and extend bit life. Inspect the cutting edges for wear before each use and replace the bit if the edge is chipped or dull.
