OEM Coolant Through Flat Bottom Carbide Drills For Blind Hole Machining

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 a 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.

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

The internal coolant channels deliver coolant directly to the cutting area, quickly reducing cutting temperature and thermal deformation while minimizing friction in the cutting zone. The flat bottom drill design completes the blind hole bottom in one process, ensuring a flat, burr-free hole bottom. The straight flute structure facilitates efficient chip evacuation, preventing clogging, and ensuring continuous and stable machining.
