Eagle Cutting Tool 1080D-045-D Drill Bit 45/64 in

Product Description

The EAGLE CUTTING TOOL 1080D-045-D is a 45/64 inch screw machine length drill bit with a 1/2 inch straight shank, manufactured in the USA. Screw machine length drills are shorter than jobber-length bits, providing greater rigidity and reduced deflection in production drilling, CNC work, and close-tolerance applications. The BG Dyno SD designation indicates a bright ground finish suited for general-purpose drilling in steel, cast iron, aluminum, and similar materials. Licensed machinists, tool-and-die technicians, and fabrication shops rely on this style of bit for repeatable, accurate hole production.

This drill bit is intended for use in metalworking and industrial machining environments where a shorter, stiffer bit is required to hold dimensional accuracy. The 45/64 inch cutting diameter suits applications requiring oversized holes for press-fit inserts, reaming prep, or clearance fits. The 1/2 inch shank is compatible with standard drill chucks, milling machine collets, and CNC tool holders accepting that shank diameter. Suitable for both manual and machine-fed operations in shop and field settings.

Key Features

• Screw machine length body provides increased rigidity and reduced bit deflection compared to jobber-length drills
• 45/64 inch cutting diameter for oversized hole applications, press fits, and reaming prep
• 1/2 inch straight shank fits standard chucks, collets, and CNC tool holders
• Bright ground finish suitable for general-purpose drilling in ferrous and non-ferrous metals

Compatibility

Designed for use in any drill press, CNC machining center, or hand drill with a chuck or collet accepting a 1/2 inch straight shank and capable of accommodating a 45/64 inch cutting diameter.

Installation Notes

This bit is installed by a machinist or trained technician. Secure the shank fully in the chuck or collet and verify runout before production use. Apply appropriate cutting fluid for the workpiece material to extend tool life and maintain hole quality. Inspect the cutting edges before each use and remove the bit from service if chipping or excessive wear is present.
