Eagle Cutting Tool 1090-041-I Hss Drill Bit 41/64 in

Product Description

The EAGLE CUTTING TOOL 1090-041-I is a 41/64-inch high speed steel (HSS) screw machine (stub length) drill bit with a 1/2-inch reduced shank. Screw machine length drill bits feature a shorter flute and overall length compared to jobber-length bits, which improves rigidity and reduces deflection during drilling. The 1/2-inch shank makes this bit compatible with standard drill chucks and CNC tooling that accept that shank diameter. HSS construction provides the hardness and heat resistance needed for production drilling in metal, wood, and plastic. This bit is suited for machinists, tool and die shops, maintenance technicians, and fabricators working on metal removal applications.

Screw machine drill bits are commonly used in machine shop environments, drill presses, turret lathes, and CNC machining centers where stub-length tools reduce tool overhang and improve hole accuracy. The 41/64-inch diameter is a common size for clearance holes, tapping preparation, and close-tolerance bore work in ferrous and non-ferrous materials. The reduced 1/2-inch shank allows use in machines and chucks that may not accommodate the full 41/64-inch diameter directly.

Key Features

• 41/64-inch cutting diameter in a stub-length screw machine format for improved rigidity
• High speed steel (HSS) construction for durability in metal, wood, and plastic drilling
• 1/2-inch reduced shank for compatibility with standard drill chucks and CNC toolholders
• Shorter flute length reduces deflection and improves hole straightness versus jobber-length bits
• Import-sourced bit designed for production and general-purpose drilling applications

Compatibility

Designed as a general-purpose screw machine length drill bit for use in drill presses, turret lathes, CNC machining centers, and hand-held drill equipment fitted with chucks that accept a 1/2-inch shank.

Installation Notes

This bit should be installed and used by machinists or qualified tradespeople familiar with proper drill press and CNC machine operation. Ensure the machine spindle is fully stopped and locked out before changing tooling. Secure the shank firmly in the chuck or toolholder to the full depth of the chuck jaws to prevent pullout during cutting. Use appropriate cutting fluid or coolant for the workpiece material to extend tool life and improve hole quality.
