The importance of meticulously prepping, starting, and finishing holes can’t be emphasized enough.

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.

BIG DAISHOWA is expanding its offering of digital boring heads to include head sizes down to the CKB1 modular tooling connection size, which means boring down to Ø.787” for Series 310 peripheric heads, and Ø.016” for Series 112 centric boring heads.

In the precision, no-room-for-error world of aerospace, manufacturers need sophisticated tool presetting like airplanes need wings.

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.

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.

We talk a lot about some of the products we offer that handle tooling while they aren’t on the spindle—and for good reason.

Otto Martin Maschinenbau GmbH & Co. KG has been manufacturing woodworking machinery since 1922. They know a thing or two about precision tools.

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”.

Using helical interpolation to open holes is common practice. And in shallow holes or one-off projects, it’s a fine choice.
