Features

1. External lubrication, double margin, drill-high precesion - High precision hole tolerance is realized, vibration is reduced in through holes and intermittent sections, and chattering is minimized to increase tool life. Excellent point strength with low cutting forces to accommodate a wide range of carbide drilling operations.
2. This series of drills is coated with a proprietary coating consisting of extreme toughness, high wear and heat resistance properties to ensure reliable and consistent tool life.
3. Finite R gash shape can realize ultra-low cutting resistance and excellent chip control.
4. Cemented carbide drills through coolant are also available.
5. Reinforced surface hardness and heat resistance by applying BHC coating / Contains carbon steel, alloy steel, gray cast iron, and ductile cast iron

▣ 2 blades, 3 blades/ External, internal refueling type/ Double margin DRILL ▣
