ATRA ACE - Manual feed
The Nitto Kohki ‘ATRA ACE’ mag drills have been specifically designed for use with TCT (Tungsten Carbide Tipped) cutters. They have the benefit of cutting in excess of 3x more holes per cutter compared to ordinary HSS (High Speed Steel) and increase productivity as they are run at far higher rotational speeds (see machine specifications). The WOJ-3200 (top) features the most advanced motor overload protection system on the market today. Customers can experience a cutting edge drill management system designed solely around saving time and money in replacement parts and cutters in addition to reducing user fatigue and downtime. It is also fitted with a unique body height adjustment to allow for twist drill cutting with the aid of a keyed chuck. The AO-5575 (bottom) also benefits from the unique motor overload protection but has a larger cutting capacity than that of the WOJ-3200. It is capable of producing a 55mm diameter hole through 75mm thick plate and also benefits from a built-in coolant system. It is fitted with a two speed gearbox, high speed for up to 32mm and the low speed for over 32mm diameters. Another feature of all the ‘ATRA ACE’ range is the One- Touch push to fit cutter replacement system, which has a self-centering tool-less chuck which reduces downtime and the need for tools to carry out the change. |
