This 6""Piece Set includes our 4-In-1 Pin Vise and 5 drill bits. The 4-In-1 Pin Vise is larger and more robust than our miniature version, highlighted by two double-ended collets for holding tools of varying sizes. Equipped with a rotating cap, the 4-In-1 Pin Vise is ideal for precision drilling, tapping and scribing. There is also a storage area beneath the handle cap for the extra collet and drill bits.
