Eagle Cutting Tool 1090-049-I Hss Drill Bit 49/64 in

Product Description

The EAGLE CUTTING TOOL 1090-049-I is a 49/64 inch high speed steel (HSS) screw machine (stub length) drill bit with a 1/2 inch reduced shank. Screw machine length drills are shorter than jobber-length bits, which increases rigidity and reduces deflection in tight spaces or on machine tool setups. The 1/2 inch shank allows this fractional-size bit to seat in standard drill chucks and toolholders rated for that shank diameter. Machinists, tool and die workers, and maintenance mechanics use bits like this for precision hole-making in metal, plastics, and composite materials.

This drill bit is suited for general metal removal work in manual drill presses, CNC machining centers, and turret lathes where a stub-length HSS bit is the preferred tooling choice. The 49/64 inch cutting diameter is commonly used when drilling to close tolerances before reaming, or when a specific non-standard hole size is required by a part print. The import designation indicates this is a value-line tooling option appropriate for production shops managing tooling cost per hole.

Key Features

• 49/64 inch cutting diameter for non-standard or close-tolerance hole applications
• High speed steel construction provides hardness and wear resistance for metal cutting
• Screw machine (stub) length body increases rigidity and reduces chatter compared to jobber-length bits
• 1/2 inch reduced shank fits standard drill chucks and toolholders without an adapter
• Minimum order quantity of 1 allows single-unit purchase for tooling replacement

Compatibility

Designed as an OEM-style replacement or tooling replenishment option for standard drill chucks and toolholders accepting a 1/2 inch shank, used in drill presses, milling machines, lathes, and CNC machining centers.

Installation Notes

Installation is performed by qualified machinists or tool room personnel. Secure the shank fully in the chuck or collet and verify runout before cutting. Power down and lock out the machine before changing tooling per standard OSHA lockout/tagout procedures. Do not exceed the recommended feed and speed parameters for the workpiece material and bit diameter.
