Can't quite fit your drill into that narrow space? No need to get a whole new set of long bits. Just pop any of your existing 1/4" hex-shank drill bits or driver bits into one of these extensions. The 12" extension allows most people to reach an 8' ceiling without a ladder, and you can even line them all up for 21" of reach! Not for use with impact tools. Each extension includes a 1" #1 Plain Hex Phillips Bit and a 2" #2 Power Groove Phillips Bit.


Features:

  • Chuck's small 5/8" diameter fits through slim holes for increased versatility
  • True one-handed operation, simply push the bit into the chuck
  • Patented All-Hex Design holds bits tight, even when removing bits from holes
  • Positive action doesn't let go until you want it to
  • Will accept any 1/4" (6 mm) hex shank accessory, with or without a power groove
  • Only chuck that accepts all standards, ANSI, JIS and DIN
  • Black oxide finish with plated steel chuck give excellent corrosion resistance
  • Replaces all magnetic and non-magnetic bit holders
  • Quick Change hex-shank and hardened extensions optimize drill torque
  • Fits all keyed and keyless chucks
  • Works in all corded and cordless drills
  • Only chuck that holds all screwdriver bits 1" and longer
  • Ideal for use with high speed drill bits, spade bits, hole saws, screwdriver bits and all 1/4" hex shank power tool accessories

Really speeds up bit changes.
Better than most of the others on the market. Good price.

Holds bits very well
I bought the 3" and am very pleased with the hold it has on any kind of bit shank I've tried. I was using a DeWalt that did OK but broke so this is working out to be a great replacement.

Quality
I purchased two of these. A 6" and about a 12 or 14". They've really come in handy for narrow gaps and mounting sinks from underneath!

Excellent extensions
I purchased the 3" and 12" Insty-Bit extensions several years ago. They hold bits better than any other extension I've used, even straight shank (no grove) & 1" bits.

Just make sure you keep them away from excess humidity. I Kept mine in a garage workshop without air conditioning in Florida (high humidity), & they've rusted after 4 years sitting in a tool box. Would be nice if they made a stainless steel version....

Would definitely recommend, & will be buying replacements soon, but will keep the new ones oiled down to protect against the humidity.

Need a long extension for a critical job. The 6" insty-bit extension I have is high quality with a tight joint so I chose this product.

I have no idea, when i'll need this item

great for gutters and extra long reach areas
Richard M on Jun 14, 2015
Works great - just don't expect it to work with impact drivers. It is a quality tool...wish they offered an impact version.

Do you release the bit by pulling the sleeve forward or by pushing it back?
A shopper on Jul 10, 2015
BEST ANSWER: Pulling it back, it is quick and easy to do.
