The EAGLE CUTTING TOOL 1090-035-I is a 35/64 inch high speed steel (HSS) slow-spiral drill bit with a 1/2 inch reduced shank, designed for precision hole-making in metal, wood, and plastic. The HSS construction provides durability and heat resistance during extended drilling operations. At 0.69 pounds, this bit is sized for use in standard 1/2 inch drill chucks and is suited for trade and production environments where consistent bore diameter and clean entry are required.
This drill bit is intended for use by machinists, pipefitters, HVAC technicians, electricians, and general trades professionals who require precise fractional sizing. The 35/64 inch diameter is a common choice for clearance holes and pre-tap applications. The 1/2 inch shank allows compatibility with a wide range of drill presses, magnetic drills, and hand drills equipped with 1/2 inch chucks.
Designed as a standard fractional HSS drill bit for use in any drill press, magnetic base drill, or hand drill equipped with a 1/2 inch chuck capacity.
Install the bit firmly into a 1/2 inch chuck and tighten securely before operation. Always wear appropriate eye protection and secure workpieces before drilling. Use cutting fluid when drilling hardened or thick metal stock to extend bit life and maintain bore quality. Inspect the cutting edges for wear before each use and replace when dulling is observed.
