Insty-Bit Insty-Lok (80138)

Insty-Bit 80138 quick change 1/4-inch bit holder


Insty-Bit is headquartered in Minnesota, along with manufacturing. Tools include: quick-change adapters, quick-change extensions, hex shank drills, countersinks, and other drilling accessories.


The Insty-Bit Insty-Lok’s tapered design follows the shape of a standard drill chuck. The chuck has a very smooth operation when inserting and removing a power bit, and bit changes can be done with one hand.

  • Total Length: 2.28″
  • Head Diameter: .95″
  • Shaft Diameter: 11/32″
  • Material: Steel – Black Oxide


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.”

Snappy Quick Change (40011)

Snappy 40011 1/4-inch quick change bit holder


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.”

  • Total Length: 2.2″
  • Head Diameter: .92″
  • Shaft Diameter: 11/32″
  • Material: Steel – Black Oxide
