Description
The Drillco 350N114 is a premium 7/32-inch Mechanics Length Drill Bit belonging to the elite Nitro® Series, engineered specifically for heavy-duty penetration in hard metals, including stainless steel and titanium. Featuring a proprietary M-7N High-Speed Steel construction with a nitride surface treatment, this tool delivers measurable hardness superiority over standard HSS bits while maintaining the flexibility required to prevent breakage in handheld applications.
Features
- Nitro® M-7N Steel: Manufactured from specialized molybdenum HSS with a nitride finish that creates a hard, protective layer for extended tool life.
- 135° Split Point: Self-centering tip eliminates “walking” on startup and reduces the thrust force required to penetrate the workpiece.
- Mechanics Length Geometry: Shorter overall length and flute length provide maximum rigidity and resistance to breakage, ideal for tight spaces.
- Black & Gold Finish: distinct surface treatment that identifies the Nitro series and maximizes lubricity during drilling.
- 3-Flat Shank: Precision-ground flats on the shank ensure a secure grip in keyless chucks, completely eliminating bit slippage under high torque.
- Versatile Application: Optimized for use in stainless steel, mild steel, and other hard alloys using both portable drills and CNC equipment.
- Made in USA: Manufactured to strict aerospace tolerances in the United States.
