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

Product Description

The EAGLE CUTTING TOOL 1080-045-D is a 45/64-inch high speed steel (HSS) slow-spiral drill bit with a 1/2-inch reduced shank, manufactured in the USA. Designed for professional metalworking and machining applications, this bit delivers controlled chip evacuation through its slow spiral (low helix) flute geometry, which reduces heat buildup and maintains cutting edge integrity in deep-hole and tough-material drilling. At 0.69 pounds, it is built for use in drill presses, milling machines, and heavy-duty hand drills. Licensed machinists and trade professionals rely on HSS construction for its balance of hardness and toughness across a wide range of workpiece materials.

This drill bit is suited for drilling operations in ferrous and non-ferrous metals, plastics, and similar materials where a slow-spiral geometry is preferred over standard twist drill angles. The 1/2-inch shank allows it to seat in standard 1/2-inch drill chucks found on benchtop and floor-standing drill presses. Domestic manufacture to USA tooling standards makes this bit a common choice in job shops, maintenance facilities, and industrial trade settings where consistent dimensional accuracy is required.

Key Features

• 45/64-inch cutting diameter for precise fractional sizing in metal and industrial applications
• High speed steel (HSS) construction provides hardness and heat resistance during extended cutting operations
• Slow spiral (SD) flute geometry promotes controlled chip flow and reduced heat in deep-hole drilling
• 1/2-inch shank fits standard drill press and machine tool chucks without a reducer
• Manufactured in the USA to commercial tooling standards

Compatibility

Designed as an OEM-style replacement or direct-use drill bit compatible with any drill press, milling machine, or heavy-duty drill accepting a 1/2-inch straight shank tooling.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or trade professionals familiar with machine tool operation and workplace safety requirements. Secure the shank fully in the chuck and verify runout before beginning a cut. Always power down and lock out the machine before changing bits or adjusting workpiece fixturing. Follow applicable OSHA machining safety guidelines and wear appropriate eye and hand protection during operation.
