Many DIY enthusiasts love to talk at length about the power of their driling machines or the special drill bits they've just acquired. In the process, other parts might be overlooked. Yet tool holders, like the drill chuck, deserve your full attention! After all, the success of your project largely depends on how well the machine and the tool, with all its various parts, work together. A good drill chuck plays a significant role in this, even if it often stays in the background. In this blog post, we'd like to highlight it and present it as what it truly is: the element that holds everything together. Let's shine a spotlight on the drill chuck!

The drill chuck is a tool holder and thus serves as the link between the tool and the machine. In this capacity, it not only bears a lot of responsibility but also has to meet a few essential requirements. A good drill chuck should securely grip the shank of the tool, hold it firmly, and transfer the generated forces to the machine. At the same time, a good drill chuck should also be practical in use.
There are many types of tool holders, such as shrink-fit chucks or collet chucks. However, by far the most commonly used is the 3-jaw drill chuck, which you've probably used yourself. The number of clamping jaws is crucial here, as it ensures good centering of the drills. The uniform force application from three sides in a good drill chuck ensures that the tool is perfectly centered.

In the past, you had to tighten the drill chuck using a ring gear. This could only be done with a tightening key, which you always had to have on hand. Moreover, such a gear drill chuck required two hands for operation. That's why, among the types of drill chucks, the keyless drill chucks have become widely adopted. These make tool changes very quick and convenient, and depending on the design, can even be opened and closed with one hand.
I have four G3's and have not had a problem with any (I also have some SN and SN2's).
In the G3 the standard is insert style which I would recommend. Others, the G3-D (Delta) and G3-Comet are direct threaded.
All of mine except one has been within Teknatool specifications of .004 or less, the one was .005 but others are .001.
I find the serrated jaws very useful for deeper items of any diameter. The 35mm spigot, 45mm spigot, and 100mm Powergrip jaws have serrations on the interior for longer spigot/tendon holding.
I do not know the capacity of your lathe but if 12" or larger you may want to look at the SN2 instead of the G3. The G3 will physically accept the 100mm powergrip and 130mm bowl jaws but is not rated for them.
I do not know if the one you are looking at is the $100 or the $150 which has four sets of jaws. I guess they are OK but I have never even installed the small cole jaws; the pin jaws are very nice; the 35mm bowl jaws has the same spigot diameter as the pin jaws.
Unless they have changed, be careful of inserts sold by Woodcraft as they may not be oem products but knock-offs. If you look at Woodcraft for inserts for 1X8 you will see there are two. One is a Nova IDNS which I believe is a real Nova, the other is a Teknatool FOR Nova chucks and I think this is the bogus one. The real one will come in a red box.
If looking just at the chuck and not the set you may want to look at Toolsplus also, you know you will get a real Nova insert.
