Eagle Cutting Tool 1090D-039-I Drill Bit 39/64 in

Product Description

The EAGLE CUTTING TOOL 1090D-039-I is a 39/64-inch screw machine length drill bit with a 1/2-inch shank diameter. Screw machine drills feature a shorter flute length than jobber bits, which reduces deflection and improves rigidity when drilling in tight spaces or on drill presses. This bit is suited for machinists, fabricators, and maintenance technicians who need consistent, accurate hole sizing in metal and similar materials. The 1/2-inch shank makes it compatible with standard drill chucks across a range of stationary and handheld equipment.

This drill bit is intended for use in machine shop environments, production drilling operations, and maintenance or repair settings where a screw machine length bit is preferred over a standard jobber length. The shorter body improves stability when boring through steel, aluminum, and similar materials. It is appropriate for both manual drill press work and CNC setup in applications requiring a 39/64-inch finished hole diameter.

Installation Notes

Installation of this bit should be performed by a qualified machinist or trained technician. Ensure the drill press or power tool is fully de-energized and the chuck is secured before inserting or removing the bit.
