Nikken’s DJ Boring Heads has been completed updated in 2014, combining the power of alloy steel with a carbide core. They are primarily used for finishing and / or deep boring operations. With the DJ Boring Head system, anyone can set it to micron accuracy. The DJ Boring Head is also the world’s smallest boring bar with a carbide insert (ø25mm). Available as standard on Nikken 2-Lock for both BT and DIN tapers our boring base holders also offer the benefits of dual contact for both flange and taper on suitable machine tools (2-Lock is also fully compatible with standard BT/DIN type spindles). 2-Lock increases the contact area considerably from around 44.4mm to 63mm (BT40) and also, as with all our NC tooling products, provides users with over 80% taper contact as standard. Additional standard options of course also include HSK and Nikken Polygon tapers.
