Eagle Cutting Tool 1212XL-028-I Hss Longboy Drill 7/16in

Product Description

The EAGLE CUTTING TOOL 1212XL-028-I is a high-speed steel (HSS) extra-length drill bit designed for deep-hole drilling applications where standard-length bits fall short. With a 7/16-inch diameter and a 12-inch overall length (OAL), this longboy-style bit provides the extended reach needed to bore through thick stock, structural members, or stacked materials in a single pass. It is suited for use by machinists, pipefitters, electricians, and general fabricators working with steel, aluminum, wood, and similar materials.

This bit is a practical choice for trade and industrial applications that require extended reach without repositioning the workpiece or using extensions. Typical use cases include boring through wall plates, structural steel, deep cavities in fabricated assemblies, and through-holes in thick material stacks. The 12-inch OAL gives clearance for deep-hole work on drill presses and handheld power drills alike.

Key Features

• 7/16-inch cutting diameter for common fastener and conduit clearance holes
• 12-inch overall length provides extended reach for deep-hole drilling
• High-speed steel (HSS) construction handles steel, aluminum, wood, and plastics
• Longboy design eliminates the need for bit extensions in deep-reach scenarios
• Minimum order quantity of 1 — available as a single unit

Compatibility

Designed as an OEM-style replacement or direct addition for standard drill chucks accepting 7/16-inch shank tooling on benchtop drill presses, magnetic drills, and handheld power drills.

Installation Notes

Secure the bit fully in the drill chuck before operation and verify the chuck key is removed prior to powering the drill. Use cutting fluid or lubricant when drilling ferrous metals to extend bit life and reduce heat buildup. Allow the bit to clear chips frequently when boring deep holes to prevent binding and overheating. Follow applicable shop safety standards and wear appropriate eye protection during all drilling operations.
