Attention:In the oil coal and other machine industries as oversize hole machining becomes more and more common, the application of VMD indexable drill can greatly improve the michining efficiency. The bright spot of VMD indexable drill: 1 Using the structure of center guide drill with better centering effect to make sure hole site a good straightness; 2 Internal and external cutter edge is applied to the structure of replaceable clamp tool. In practical using the most vulnerable is external edge clamp.replacing clamp can avoid the drill scrapped to save the tool cost. 3 Adjusting external clamp the dimension of drill machining can vary with 0-5mm 4 Cutter head and shank are modular structure only change different length shank during processing the different depth of the hole 5 Drill with center water hole can cool insert better,extend insert life and accelerate clip evacuation 6 Using indexable carbide insert cutting with high speed and feed, surface finish has greatly improved. 7 In the process security is greatly improved as chip is breaker not slender twining of traditional greatly twist drill 8 In the process, automatic continuous feed and don't need tool back off to chip, and efficiency is greatly improved.
