I bought it with Takura 's Chuck Arbor. Keyless chuck is the first use. Since I had only used chucks of table turning lathes and desk-top milling machines so far, I felt the accuracy of accuracy on chucks which actually turn around and turn null. In normal use the bit will not run out and exchange is easy. I did get lost at the price before purchase, but now I think that it was good to purchase.
I bought it for an inexpensive desktop milling machine made in China. And I was made aware of how much it was polluted precisely with the same keyless drill chuck made in China that I used up to now. The set drill is not blur at all! Made in Japan that is truly crowned around the world. We confidently recommend this product to all metal processing enthusiasts feeling limit to Chinese machines! It is! It is!
