Eagle Cutting Tool 1212XL-031-I Hss Longboy Drill Bit

Product Description

The EAGLE CUTTING TOOL 1212XL-031-I is a high-speed steel (HSS) longboy drill bit designed for deep-hole drilling applications in metal, wood, and similar materials. With a 31/64 inch diameter and a 12 inch overall length (OAL), this extended-length bit reaches into deep cavities, long cross-holes, and tight-clearance setups where standard-length bits fall short. The 9 inch flute length provides extended chip evacuation over the full depth of the bore. Machinists, tool-and-die technicians, and general metalworking shops will find this bit suited to production and maintenance drilling where reach is the primary constraint.

This longboy drill bit is used in applications requiring extended reach beyond standard jobber-length tooling. Common install scenarios include drilling through thick structural sections, long through-holes in fixtures and fabrications, and deep pilot holes in manufacturing setups. It is run in drill presses, CNC machining centers, and hand-held drill equipment where the spindle and workholding setup can support the extended length without excessive deflection.

Key Features

• 31/64 inch diameter for fractional sizing in standard drill sequences
• 12 inch overall length provides extended reach into deep workpieces
• 9 inch flute length supports chip clearance over long bore depths
• High-speed steel (HSS) construction offers toughness and resharpening capability
• Longboy geometry suited to through-holes and deep-cavity drilling where standard bits cannot reach

Compatibility

Designed as an OEM-style extended-length replacement or stock drill bit compatible with standard drill chucks and collet systems accepting 31/64 inch shank diameters in drill press, manual, and CNC drilling applications.

Installation Notes

Extended-length drill bits should be secured in a properly sized chuck or collet and run at reduced RPM compared to standard-length bits of the same diameter to minimize deflection and bit breakage. Ensure the workpiece is firmly clamped before drilling, and use appropriate cutting fluid when drilling metals to extend tool life. Inspect the bit for runout before beginning a deep-hole operation. This tooling should be handled and stored by qualified machine operators or maintenance technicians following applicable shop safety procedures.
