Ultra-hard drill for deep hole machining of small diameters - Cross groove drill (for non-ferrous metals and plastics)
SXG--DN
Achieving ultra-deep hole machining with an L/D ratio of 30 to 50 using external lubrication!
Aren't you under the impression that coolant-through equipment is essential for hole machining with an L/D ratio of 30 or more? The new cross-grooved drill draws coolant into the hole's interior by incorporating a main groove and a reverse twist groove on the drill's outer circumference when the drill is rotated. Inside the hole, the coolant is retained in the grooves on the outer circumference, improving "cooling" and "lubrication," resulting in excellent cutting performance and significantly enhancing the surface roughness of the hole's inner surface. Additionally, the margin-less design equalizes the holding power and suppresses the occurrence of hole bending.

Company information
Our company was established in 1934 as the first factory in Japan specializing in the manufacture of metal cutting saw blades. Since then, we have inherited the spirit of development cultivated at the time of our founding and have continuously challenged ourselves with new technologies and processing methods. In 1954, we began manufacturing carbide precision cutting tools, pioneering a new field in cutting processing, and we have become unmatched in the world of micro-diameter tools. The knife-making technology developed by ATOM continues to evolve, and our refined know-how has made the sub-micron world possible. All of us at ATOM stand at the origin of "manufacturing," pouring our soul and sincerity into each tool as we continue to produce precision cutting tools.
