Features 
- Japanese Industrial Standard (LIST 500): Manufactured to the NACHI LIST 500 standard, globally popular and trusted by professional technicians for durability and precision.
- High-Grade HSS Material: Made from premium high-speed steel with an optimal balance between hardness and toughness, reducing the risk of breakage in the workpiece even under heavy use.
- Excellent Heat Resistance: Superior resistance to heat buildup during operation, helping maintain cutting edge sharpness many times longer than conventional drill bits.
- Optimized Spiral Flute: Standard spiral flute designed for efficient chip evacuation, reducing clogging and lowering tip temperature while drilling.

Applications 
- Heavy Metalworking: Drilling mild steel, cast iron, structural steel, and general alloys.
- Tapping Preparation: The 7.5 mm size is commonly used for pre-drilling pilot holes for tapping special thread sizes, or for structural work requiring an exact 7.5 mm hole.
- Aluminum & Non-Ferrous Metals: Drilling aluminum, copper, brass, as well as engineering plastics and hardwood
- Maintenance & Construction: Machinery maintenance, steel structure assembly, and high-quality DIY projects.
