Owning multiple drills and drivers requires extra storage…and adds to overall cost. But having the right drill accessories costs less, uses less space, yet creates a very convenient all-in-one drill / driver.
What are these adapters for?
There are several types of quick change adapters and drill chuck conversion tools aimed at a specific purpose. The brands listed offer dedicated quick change adapters to convert your ⅜-inch or ½-inch power and cordless drills to accept ¼-inch hex power bits., which are different than quick change extensions, which vary in length, or chuck conversion tools, which do the opposite and convert a ¼-inch quick-change to a drill chuck.
This gives you the same flexibility and work efficiency of a ¼-inch drill driver without buying another drill.
What’s a power bit (aka ball detent)?
The deep groove at the end of the shank is engaged by a metal ball or wire from a chuck to lock the bit in place.
I keep the Insty-Bit Insty-Lok (80138) in my personal tool collection. The tolerances are just right in keeping a bit held securely, while the operation of bit insertion and one-handed removal is super smooth and effortless.
Combine the well machined design with 100% metal parts; in my view Insty-Bit is providing all that a user can ask for in assuring a top quality drill accessory.
Snappy Industrial Quick Change
A very close second to the Insty-Bit, is the Snappy Industrial Quick Change Chuck (40011), which is also made from 100% metal parts. Both products seem very similar in many ways, and I’d be happy with either.
The operation of smooth bit insertion and removal – lets you know the quality of craftsmanship.
Snappy says “Our namesake is the “snap” that’s heard when a drill bit, driver bit or other tool is pushed into our patented quick change chuck.” This is true, there’s a definitive sound to let you now the power bit is locked in.
