LV® Tool's internal coolant tungsten carbide drills are engineered for high-efficiency machining of challenging materials, including alloy steel, cast iron, stainless steel, and hardened steels. The through-coolant design ensures optimal chip evacuation and superior cooling at the cutting edge, significantly extending tool life and improving hole quality. Manufactured from premium German and Japanese carbide rods, these drills offer exceptional rigidity and wear resistance. Ideal for demanding applications in the automotive, aerospace, and mold & die industries, our drills provide consistent, reliable performance. As a leading cutting tool manufacturer, we offer a wide range of diameters and lengths to meet your specific production needs.
Precision Drilling with Enhanced Chip Evacuation
The LV® Tool Internal Coolant Carbide Drills are engineered for superior performance in high-demand drilling applications. The internal coolant channels deliver pressurized coolant directly to the cutting edge, effectively flushing chips out of the hole, reducing heat buildup, and preventing tool breakage. This advanced design allows for higher cutting speeds and feed rates, resulting in increased productivity and improved surface finish, even in deep-hole drilling operations.
