Eagle Cutting Tool 1090D-049-I 49/64 Drill Bit 1/2 Shank

Product Description

The EAGLE CUTTING TOOL 1090D-049-I is a 49/64-inch diameter screw drive (SD) drill bit with a 1/2-inch shank, built for professional drilling applications in metal, wood, and composite materials. The BG Dyno SD designation indicates a self-drilling or screw-drive geometry optimized for controlled entry and clean hole production. At 0.69 pounds, this is a solid, tool-grade bit suited for bench-press or hand-drill operation. Machinists, fabricators, and trade professionals who require precise fractional hole sizes will find this bit a reliable addition to the shop or field kit.

This drill bit is designed for trade and industrial use where 49/64-inch hole sizing is required, such as fastener clearance holes, conduit knockout prep, or mechanical fitting work. The 1/2-inch shank makes it compatible with standard 1/2-inch drill chucks common on heavy-duty corded and drill-press setups. It is imported and intended for professional production or repetitive drilling environments where accurate fractional sizing matters.
