The EAGLE CUTTING TOOL 1090D-042-I is a 21/32 inch bright gold Dyno SD twist drill bit with a 1/2 inch shank, designed for professional drilling applications in metal, wood, and general-purpose materials. The bright gold finish indicates a heat-treated surface treatment that improves lubricity and extends cutting life under repeated use. Weighing 0.69 pounds, this is a solid, full-size drill bit suited for use in standard drill presses or heavy-duty hand drills. It is intended for trade professionals and skilled tradespeople who require consistent, accurate hole sizing in production or maintenance work.
This drill bit is applicable across a range of trade settings including mechanical, plumbing rough-in, electrical conduit work, and general fabrication. The 1/2 inch shank makes it compatible with most 1/2 inch chuck drill presses and heavy-duty corded drills commonly found in shop and field environments. The 21/32 inch cutting diameter is a standard fractional size frequently specified in structural and mechanical applications requiring precise bore dimensions.
Designed as a standard fractional twist drill bit compatible with 1/2 inch chuck drill presses and heavy-duty hand drills used in professional trade and fabrication applications.
Install and remove drill bits only when the drill or drill press is fully powered down and the chuck has stopped rotating. Secure the 1/2 inch shank firmly in the chuck before operation to prevent slippage and bit damage. Use appropriate cutting fluid when drilling hard metals to reduce heat and extend bit life. Follow applicable shop safety standards and wear appropriate eye and hand protection during all drilling operations.
