NT Tool Corp. has introduced a line of collets that can deliver coolant in tools at up to 1,000 psi. The patented 100TG Coolant Collets have a one-piece, steel design with short slots that prevent coolant from reaching the face of the collet. The company says this design eliminates the need for rubber or silicone seals, and allows for greater coolant pressure. Also, the company says the patented one-piece design reduces the loss of accuracy associated with multi-piece designs, and leads to increased collet life.
The company says its 100TG-OH Coolant Collets are compatible with all manufacturers' 100TG chucks.
The 100TG-OH Coolant Collets are available in sizes from 0.234375 in. to 1 in. in 0.015625 in. increments. Metric collets are available in standard sizes from 6mm to 26mm. www.nttoolusa.com
