The EF-Series of high penetration rate drills now include a line of sub-micro grain carbide coolant-fed micro drills. The EF High Performance Micro Drills range from 0.0295" (0.75mm) up to 0.1181" (3.00mm) in diameter, are all coolant through design, and are ideal for medical, aerospace, and precision automotive applications when producing very small deep holes in steel, cast iron, stainless steels, and non-ferrous materials. All tools are 6xD length and can accommodate most production applications.
The face geometry of the EF High Performance Micro Drills generates short chips in the drill operation, ensuring high drill hole accuracy. The micro face point and flute geometry, in addition to the coolant-fed design, enable excellent chip evacuation for the highest possible drilling speed, while reducing the need for peck cycles or clearing chips. The drills have a TiALN T99 multi-layer PVD coating for added heat- and wear-resistance, reducing built-up edges and edge chipping while increasing tool life. In addition, the large central tool shank channel guarantees maximum coolant intake capacity, allowing optimal coolant transfer.
The internal coolant supply enables economically efficient, high performance machining down to even the smallest drilling diameter of 0.75 mm. Drills also feature a double margin design for added stability and superior hole surface finish.
Emuge EF series drills are the result of extensive research and development and incorporate special geometry, proprietary carbide grades, and a PVD coating design that is unique to the industry. The result is 3x to 5x faster penetration rate than conventional carbide and cobalt drills, in addition to high quality threads and longer tool life.
