Comprehensive 19-Piece Metric Range: Includes 1.0 mm to 10.0 mm bit diameters in 0.5 mm steps, covering all standard hole sizing and pre-tapping requirements.
Tough HSS-R Steel with Black Oxide Finish: Precision hot-rolled high-speed steel resists breakage under torsional stress, while the black oxide coating reduces friction and thermal buildup.
118° Split-Point Self-Centering Geometry: Bites into surfaces immediately without wandering or skidding, ensuring clean hole placement in sheet metals and structural steel.
Broad Multi-Substrate Capability: Engineered for consistent boring through structural carbon steel up to 900 N/mm², cast iron, non-ferrous metals, dense plastics, and timber.
Heavy-Duty Steel Indexed Storage Case: Rugged metal fold-out cassette protects bits from jobsite impact, keeps sizes neatly organized, and enables quick one-handed selection across Nepal.
