There’s more than one way to skin a CAT…or should we say HSK in this case.

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.

The limitations of using milling tools to prepare holes for finishing become apparent as hole depth and volume increase. Enter the relatively simple and affordable twin cutter, which can solve this and virtually any other holemaking problem.

We’ve built our name on tool holders, boring tools, cutting tools and specialized solutions for the everyday and most demanding machining operations. You may be surprised to learn we have deep expertise in lathe tooling as well. We have to. Lathes are critical to the development and production of our tools.

In order to take full advantage of a machine tool's capabilities, you must have the tooling to unlock a machine’s full capability. Here is some advice for making the most of a new machine tool with the right tooling.

Learn five key factors to consider when selecting boring tools to improve performance, reduce costs and ensure part quality.

BIG DAISHOWA announces the introduction of the world’s smallest hydraulic chuck for HSK-E25 machine spindles, thus completing its extensive range of Slim Hydraulic Chucks.

BIG DAISHOWA introduces Hydraulic Chucks for Swiss Lathes, the first improvement to this technology in more than 30 years.

Anyone who’s made holes understands the difficulties that can arise: vibration, wander and even breakage. When it comes to production-level volume, these issues become even more limiting. Many turn to helical interpolation with a mill as a reliable way to rough out holes. We’re here to tell you there’s a faster, easier option.

There are many advantages to turning (pun intended) to an underutilized operation that virtually every machining center is capable of: OD turning — otherwise known as “outer diameter turning”, “pin turning”, or “boss milling”.

The Twin Cutter’s ability to take on heavier cuts allows shops to be more efficient.

When it comes to dialing in an ER system’s performance to match a specific application’s requirements or long life, there are three components to consider: the collet, the body of the holder and the nut.

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.
