Bosch BL2631 1/16 in. x 6 in. aircraft drill bit 🛠
Product description
This extra-length drill bit from Bosch is made for reaching deeper holes while keeping controlled heat and longer life during metal and wood drilling tasks. Its aircraft-style black oxide finish and speed-helix design aim to cut faster and resist wear, which is useful when working on projects that need extended reach or repeated drilling.
Key Points
The speed-helix geometry is designed to improve chip evacuation and reduce drilling time, according to the manufacturer. The black oxide coating helps resist corrosion and lowers friction for smoother penetration. This 1/16 inch diameter, 6 inch overall length configuration provides extra reach compared with standard twist bits, making it practical for deep drilling in thin materials or fixtures. Consider that very thin diameters like 1/16 inch can be more prone to bending if used at high speed or with excessive lateral force.
Technical Specifications
- Name: Bosch BL2631 1/16 in. x 6 in. Extra Length Aircraft Black Oxide Drill Bit

Usage Recommendations
Use moderate spindle speeds and steady feed when drilling metals to minimize bit deflection and heat buildup. For best results in wood and plastics, keep the drill aligned and avoid excessive side pressure to preserve bit life. When entering thin sheets or laminated surfaces, a backing board can help prevent tear-out and produce a cleaner exit hole. Regular sharpening is possible but check the small diameter carefully to maintain correct point angle and cutting edges.
Advantages
The extended length lets you access recessed fasteners or reach through assemblies without switching to longer, less rigid setups. Users will notice reduced heat and improved durability compared with some conventional high speed steel bits, according to Bosch. The wide range of compatible materials makes this bit versatile for workshops and maintenance tasks where a narrow, long bit is required.
