We have DirectDex BTA-style deep-hole drilling heads, inserts, and pads! These drills provide low cost per bore and can effectively perform. You can use the indexable inserts without the complex component count associated with cartridge-style tools. Furthermore, they are directly interchangeable with Sandvik’s CoroDrill® 800 series of tools. DirectDex 800 drills cover a wide range from 25 mm to 65 mm (0.984” to 2.559”).
We supply both Sunnen and Sandvik drill head inserts here at BTA Heller-Sunnen. By doing so, you are offered a large variety of indexable inserts for many different purposes. We also offer a large bore size range. Having the right drill bit is crucial to any project. If it is too small, The material’s density will be too great. If it is too large, you could ruin the material you are working with. Here are the bore sizes that we currently offer.
