【Product Introduction】
The AMG Solid Carbide Coolant-Through Flat Bottom Drill D14xL40xD10xL90 is manufactured using high-quality ultra-fine grain solid carbide with precision grinding, offering high hardness, excellent wear resistance, and superior anti-chipping performance. The flat bottom tip design is ideal for blind hole and step hole machining, ensuring flat hole bottom and avoiding secondary processing. The coolant-through channel delivers high-pressure coolant directly to the cutting zone for precise cooling and chip evacuation, reducing cutting temperatures, extending tool life, and ensuring efficient, stable machining.

【Applications】
Suitable for precision machining of blind holes, step holes, flat bottom holes, and through-hole chamfering. Widely used in mold manufacturing, mechanical structural parts, and stainless steel component deep hole machining. It is compatible with carbon steel, alloy steel, stainless steel, aluminum alloys.
