1/4-Inch Quick Change Chucks

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 and driver.

There are several types of quick change adapters and drill chuck conversion tools aimed at a specific purpose:

This articles focuses on the following drill conversion,

Quick Change Chuck

1/4" Quick Change Drill Adapter

Using the jaws of a ⅜-inch and ½-inch power or cordless drill, convert to a ¼-inch quick change chuck.

Quick and easy transformation.

Get the same flexibility and work efficiency of a ¼-inch drill driver without buying another drill.

Power Bit (ball detent)

Phillips power groove bit

A metal ball or wire inside the quick change chuck securely engages the deep groove at the end of the shank when the bit’s installed.

The collar on a quick change chuck needs to be moved forward or backward to release the locking effect on the shank.

Insty-Bit has it’s headquarters and manufacturing facilities in Minnesota. Tools include: quick-change adapters, quick-change extensions, hex shank drills, countersinks, and other drilling accessories.

I keep the Insty-Bit Insty-Lok (80138) in my personal tool collection. The tapered design follows the shape of a standard drill chuck, creating a nice flow, but mainly the operation is silky smooth and bit changes are quick and easy with one hand.

Regarding impact-readiness for the #80138, Insty-Bit says, “With our chuck, if you were driving 1 ½” drywall screws with your impact drill you would have no problems with our chuck. However, if you were to put a ½” nutsetter and drive lag bolts into pressure treated wood with an impact drill, you would definitely run into issues.”

An equally great product and sharing many similarities in function and build quality to Insty-Bit, is the Snappy Industrial Quick Change Chuck (40011).

Snappy Tools is based in Texas and “proudly Made in the USA”.

Instead of a tapered design to match a drills chuck, the Snappy Quick Change Chuck follows the look of an impact driver with a snub nose design.

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.
