Description
The Bright Nails 4.5mm x 126mm Long Series HSS Drill Bit (HSGL4.5B) is designed for precision deep drilling where extra reach is needed beyond standard drill bits. Manufactured from high speed steel (HSS), it delivers reliable strength, heat resistance and consistent cutting performance for use on mild steel, plastics and timber.
The long series design allows access through box section, frames and recessed fixing points without the need for extensions. Precision-ground flutes support efficient swarf removal, reducing friction and helping produce cleaner, more accurate holes. Ideal for engineering, fabrication, maintenance and general site work.
