Eagle Cutting Tool 1090-058-I Hss Drill Bit 29/32 in

Product Description

The EAGLE CUTTING TOOL 1090-058-I is a 29/32-inch high speed steel (HSS) slow spiral drill bit with a 1/2-inch reduced shank. Slow spiral (SD) geometry moves chips out of the hole efficiently when drilling deep or in gummy materials, reducing heat buildup and extending cutting edge life. The 1/2-inch shank allows use in standard 1/2-inch chuck capacity drill presses, magnetic drills, and heavy-duty handheld drills. This bit is suited for machinists, maintenance technicians, pipefitters, and fabricators who need a large-diameter hole in metal, wood, or composite materials.

This drill bit is used in shop and field applications where a fractional size close to 29/32 inch is required. Typical scenarios include enlarging pilot holes, drilling clearance holes for bolts and fasteners, fabrication of brackets, and maintenance work on mechanical equipment. The slow spiral design is especially effective in soft metals such as aluminum, copper, and mild steel, as well as in plastics and laminates where a standard spiral might grab or tear the material.

Key Features

• 29/32-inch cutting diameter in a fractional HSS drill bit
• Slow spiral (SD) flute geometry reduces chip packing and heat in soft and gummy materials
• 1/2-inch shank fits standard 1/2-inch drill press and handheld drill chucks
• High speed steel construction provides hardness and wear resistance for general-purpose metal drilling
• Lightweight at 0.69 pounds for easy handling and chuck mounting

Compatibility

Designed as a general-purpose replacement or add-on drill bit for use in any 1/2-inch capacity drill press, magnetic drill base, or handheld drill driver. Fits standard 3-jaw and keyless chucks accepting 1/2-inch shanks.

Installation Notes

A licensed machinist or qualified maintenance technician should secure the 1/2-inch shank fully into the chuck before operation, confirming the bit runs true with minimal runout. Always ensure the workpiece is clamped or fixtured before drilling to prevent workpiece rotation. Use appropriate cutting fluid for metal applications to extend edge life and reduce heat. Wear eye protection and follow applicable OSHA machine guarding requirements when operating drill presses or rotary drilling equipment.
