Eagle Cutting Tool 1090-112-I Hss Slow Drill 1-3/16 in

Product Description

The EAGLE CUTTING TOOL 1090-112-I is a high speed steel (HSS) slow-spiral drill bit with a 1-3/16 inch cutting diameter and a 1/2 inch reduced shank. Slow-spiral geometry produces lower helix angles, which improves chip clearance and reduces heat buildup when boring through hard or tough materials. This bit is designed for heavy-duty metal drilling applications where standard jobber-length drills lack the rigidity or cutting geometry required. Machinists, tooling fabricators, and maintenance trades install this style of drill on drill presses, milling machines, and CNC equipment.

This drill bit suits metal fabrication shops, industrial maintenance, and machine shops working with hard ferrous metals, alloy steels, cast iron, and similar tough materials. The 1/2 inch shank makes it compatible with standard drill press chucks and tool holders commonly found in production and repair environments. The 1-3/16 inch diameter is a specialty size used when precision bored holes or close-tolerance fits are required at that specific dimension.

Key Features

• 1-3/16 inch cutting diameter for specialty bore applications
• High speed steel construction provides hardness and wear resistance for metal drilling
• Slow-spiral flute geometry reduces heat buildup and aids chip evacuation in tough materials
• 1/2 inch reduced shank fits standard 1/2 inch drill press chucks and tool holders
• Minimum order quantity of 1, suitable for single-unit procurement

Compatibility

Designed as an OEM-style replacement or direct-use drill bit for drill presses, milling machines, and similar equipment equipped with a 1/2 inch chuck or collet holder.

Installation Notes

This bit is installed by a machinist or qualified tooling technician. Always de-energize and lock out the machine before changing tooling per OSHA lockout/tagout procedures. Secure the shank fully in the chuck and verify runout before operating at speed. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain hole quality.
