Eagle Cutting Tool 1080-044-D Hss Slow Spiral Drill Bit

Product Description

The EAGLE CUTTING TOOL 1080-044-D is a high speed steel (HSS) slow spiral drill bit with an 11/16 inch cutting diameter and a 1/2 inch reduced shank. Slow spiral (SD) geometry reduces chip load and heat buildup when drilling through tough, abrasive, or hard materials, making this bit well suited for demanding production and maintenance applications. The HSS construction provides the hardness and wear resistance needed for repeated use in metal, wood, and composite materials. This bit is used by machinists, millwrights, electricians, and general trade professionals working with drill presses, magnetic drills, or heavy-duty hand drills.

The 1/2 inch shank allows this 11/16 inch diameter bit to fit standard 1/2 inch drill chucks without requiring a larger machine spindle. This makes it a practical choice for shops and field crews that need larger-diameter drilling capacity from common 1/2 inch chuck equipment. The slow spiral flute design is particularly effective when drilling plastics, soft metals, and other materials prone to grab or chatter at higher chip-load rates. Domestic USA manufacture is noted on the product designation.

Key Features

• 11/16 inch cutting diameter with reduced 1/2 inch straight shank for standard chuck compatibility
• High speed steel (HSS) construction for hardness and wear resistance across a range of materials
• Slow spiral (SD) flute geometry reduces chip load and heat, minimizing grab in soft or abrasive materials
• USA manufactured per product designation
• Minimum order quantity of 1 unit

Compatibility

Designed for use in any 1/2 inch drill chuck, including drill presses, magnetic base drills, and heavy-duty corded hand drills rated for 1/2 inch shank tooling.

Installation Notes

This bit is installed and operated by machinists, electricians, millwrights, or maintenance trade professionals. Always secure the shank fully in the chuck and confirm the chuck is tightened before operation. Use appropriate cutting fluid or coolant when drilling metals to extend tool life and maintain dimensional accuracy. Inspect the cutting edges for wear or damage before each use and replace if chipping or dulling is observed.
