Insty-Bit® Quick Change Extensions

Item #

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.


  • 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
