Used to secure a tool during the threading of a workpiece, a threading tool holder collet is an indispensable device for any creative machining project. After being inserted into the holder, a quick tightening of the collet ensures the cutting tool is firmly in place while its threading magic takes place.
A vast selection of threading tool holder collets may be suitable for various types of cutting tools and workpieces. Those with a round shape are commonly employed to support round-edged drill bits and end mills, whereas square and hexagonal collets have also been developed for more angular pieces.
The proper tool for the job is essential in cutting work, and this is no different when it comes to selecting a collet. The collet size should match whatever cutting tool is being used – a 1/4″ cutting tool calls for a 1/4″ collet – but special attention must also be paid to its shape. A collet designed for a square cutting tool must be square itself to maximize cutting efficiency and provide the finished product desired.
For threading purposes, collets are the obvious choice among tool holders, crafted from a wide array of materials – from steel to the more costly carbide and beyond. These dense pieces are designed to endure the high workloads associated with accurate threading at quick rates.
A collet wrench is employed to lock the threading tool holder collet in place. Insert the spanner into the slot and twist it until it is secure. Once complete, draw back the wrench and insert the cutter firmly into the now-fixed collet.
The collet provides a secure base from which the cutting tool diligently creates the desired thread pattern within the workpiece. As said workpiece is spun, the blade operating in tandem meticulously corresponds in both direction and velocity in order to sculpt the desired threads.
With every back and forth stroke of the cutting tool, miniscule fragments of the workpiece are sliced away and gently settle into the chip tray below. These chips are then set aside for disposal.
After the cutting process is finalized, the pressure on the collet is conducted, resulting in the cutting tool being disengaged from its connecting point. Following this step, the collet is subsequently taken out of its embedment in the tool holder and substituted with a new one.
Threading cannot be done without proper tool holder collets – designed for holding the cutting tool in its position while being used. Such collets come in numerous sizes and types, tailored to fit various cutting tools and workpieces. Depending on the budget and required performance, collets are crafted using diverse materials from more economical steel to expensive carbide and hard materials with extraordinary resistance to high speeds and pressures of threading.
