Drill America 8″ Extra-Length HSS Drill Bits — LongBoy Type for Deep Reach Drilling
The Drill America 8″ Extra-Length HSS Drill Bits, commonly referred to as LongBoy drills, are engineered for applications requiring extended reach beyond standard jobber and mechanic length drills. With an overall length of 8 inches, these drills are ideal for drilling deep, obstructed, or hard-to-access holes in metal, wood, and plastic.
Manufactured from high speed steel (HSS), these extra-length drill bits provide a strong balance of toughness, heat resistance, and durability. The longer body allows access into cavities, frames, tubing, and assemblies where shorter drills cannot reach, making them a staple for fabrication, maintenance, and installation work.
These drills are designed for use in standard drill chucks and are best suited for controlled drilling operations where alignment and steady feed are maintained to minimize deflection.
Key Features
- 8″ overall length for deep and hard-to-reach drilling applications.
- High Speed Steel (HSS) construction for durability and heat resistance.
- Extra-length body provides extended reach without extensions.
- Compatible with standard drill chucks.
- Ideal for fabrication, maintenance, and installation work.
