When high accuracy, long tool life or high-speed capabilities are important, collet chucks are often the holder of choice.

Did you know we have a stand-alone catalog containing 14 precision micro end mill geometries?

BIG DAISHOWA introduces the Perfect Jet Collet, designed to optimize coolant supply in high-speed operations, resulting in better coolant delivery and the option to seal the collet for coolant-through tools.

BIG DAISHOWA has introduced MEGA ER Grip, a new premium ER collet chuck system featuring the best runout accuracy in the industry: .00012" (3 microns) at 5xD.

Manufacturing miniature parts and features is not new. In the past, EDM and laser technologies were used to create these features. Although these technologies worked for low volume jobs, they are not practical for the high volume micro applications that are in demand today.

BIG DAISHOWA’s Mega ER Grip was designed to outperform all standard ER systems in the four most critical areas of tool holder performance: clamping force, concentricity, rigidity and balance at high spindle speeds.
