Eagle Cutting Tool 1090-052-I Silver Deming Drill Bit

Product Description

The EAGLE CUTTING TOOL 1090-052-I is a high speed steel (HSS) Silver Deming drill bit with a 13/16-inch cutting diameter and a reduced 1/2-inch straight shank. Silver Deming bits are designed to bore large-diameter holes in metal, wood, and plastic using a standard 1/2-inch chuck, eliminating the need for a larger, dedicated drill. The HSS construction provides the hardness and heat resistance required for repetitive drilling in ferrous and non-ferrous materials. This bit is a practical choice for machinists, pipefitters, electricians, and general fabricators who need oversized holes without specialized equipment.

Silver Deming drill bits are commonly used in industrial maintenance, fabrication shops, and field service applications where holes larger than standard jobber-length bits allow must be drilled through metal plate, pipe flanges, electrical enclosures, or structural steel. The 1/2-inch reduced shank allows the bit to be used in any standard 1/2-inch keyed or keyless chuck, making it versatile across a wide range of corded drills and drill presses. This import-grade bit suits production environments where tooling turnover is expected.

Key Features

• 13/16-inch cutting diameter for large-diameter hole applications
• Reduced 1/2-inch straight shank fits standard 1/2-inch drill chucks
• High speed steel construction resists heat buildup during metal drilling
• Silver Deming design bridges the gap between standard jobber bits and spade or annular cutters
• Minimum order quantity of 1 for single-unit procurement

Compatibility

Designed for use in any drill press or handheld drill equipped with a 1/2-inch chuck capacity. Suitable for drilling ferrous metals, non-ferrous metals, wood, and plastics.

Installation Notes

This bit should be installed in a 1/2-inch drill press chuck or heavy-duty handheld drill; use at appropriate RPM for the material and diameter being drilled, as large-diameter bits require slower speeds than standard jobber bits. Apply cutting fluid when drilling steel or cast iron to extend tool life and improve hole quality. Secure the workpiece firmly before drilling to prevent rotation or movement. Inspect the cutting edges before each use and replace if chipping or dullness is observed.
