## Description

NT USA's Super Tite-Lock Milling Chucks are the best option on the market when it comes to heavy-milling applications. With far superior gripping force and accuracy than standard sidelock holders, these chucks can handle even the most strenuous machining forces. NT USA's patented T-Slit design prevents any tool pull-out or slippage. Every holder is sealed for center-thru coolant use, and is compatible with metal-sealed reduction sleeves if you want to clamp smaller tool sizes (visit www.nttoolusa.com for details). Each holder you purchase on Amazon comes with a complimentary spanner as well, so you can use your new chuck right out of the box! ID Size: 20mm Projection Length: 120mm
