Eagle Cutting Tool 1090-117-I Hss Drill Bit 1-17/64 in

Product Description

The EAGLE CUTTING TOOL 1090-117-I is a high-speed steel (HSS) screw machine length drill bit ground to a 1-17/64 inch diameter with a 1/2 inch reduced shank. Screw machine length bits are shorter than jobber-length drills, which increases rigidity and reduces deflection in production drilling and CNC applications. The HSS construction handles a broad range of workpiece materials including mild steel, aluminum, brass, and thermoplastics. This bit is an import-grade tool suited for general-purpose metal fabrication, machine shop work, and maintenance drilling where a stubby, stiff profile is required.

This drill bit is intended for use in drill presses, milling machines, turret lathes, and CNC machining centers where a 1/2 inch collet or chuck accepts the reduced shank. The screw machine (stub) length format is common in production environments where clearance is limited or where chatter and runout must be minimized. Maintenance technicians, machinists, and fabricators working in industrial, commercial, or trade settings will find this diameter useful for bolt clearance holes, pilot drilling, and general metalworking tasks.

Key Features

• 1-17/64 inch cutting diameter for precise bolt clearance and metalworking applications
• High-speed steel construction provides heat and wear resistance during drilling
• 1/2 inch shank fits standard drill press chucks and CNC tool holders
• Screw machine (stub) length body increases stiffness and reduces deflection
• Import-grade pricing suitable for production use and tooling stock

Compatibility

Designed as a general-purpose replacement or stock drill bit for any drill press, lathe, or machining center equipped with a 1/2 inch chuck or collet capable of accepting a reduced-shank stub drill.

Installation Notes

Installation should be performed by a qualified machinist or tradesperson familiar with rotating tool safety. Secure the shank fully in the chuck or collet and verify runout before beginning a cut. Always power down and de-energize the machine before changing tooling. Follow applicable shop safety standards and wear appropriate eye protection when operating drilling equipment.
