Hello manager Good day. This is Daria from ht-tools in China. I am glad to write to you. hope this email will not disturb you. Our company mainly produce collets, tool holders, chucks, vise, nut, etc. Now i will introduce one new product of 2020. It is dust chip extraction nut . The Tornado Nut by HT-TOOLS helps with the removal of waste typically but not exclusively when nesting. Simply the Tornado Nut replaces the standard nut on your collet chuck with the collet locking into the Tornado Nut. The vortex created by the nut lifts the waste from the table enabling the overhead dust extraction to remove the waste. With the waste removed your tool life is extended, your quality of cut is improved and the working environment is cleaner and healthier. Tornado Nut is a worthy accessory to have along with your other Routing Tools. 1.material:Aluminum Alloy 2.Type: ER25/ER32/ER40/OZ25/OZ32 4.Balance nuts also available. 5.
