The 4mm Spiral Drill Bit Set with reusable Centrotec shank provides a precise, compact and durable solution for drilling wood, metal and plastic. Precision ground HSS steel stays sharper longer for precise hole drilling and a long service life.
The Festool Centrotec System is designed to deliver a better transfer of force between the drill and the bit with no chance for bit slippage or marring of the bit. The Centrotec Chuck design enables a weight reduction and a reduction in length. The quick-change Centrotec system delivers faster, more efficient means of changing bits and driver tips than any keyless chuck system and virtually eliminates run out.
  • HSS polished spiral bits for metal, plastic, and wood
  • High Speed Steel (HSS) bits are able to withstand the high tempteratures of drilling in metal not reccomended for carbon steel bits
  • Three piece design with replaceable spiral bit, Centrotec hex shank for no-slip usage, and set screw
  • Works in Festool Centrotec chuck for reduced length and weight compared to standard chucks
  • (3) HSS Spiral Drill Bits
  • Set Screw
  • Allen Wrench

Great Value - Reusable Shank!
Bit packages include 1) reusable Centrotec shank with installed bit 2) two replacement bits and 3) an allen wrench.

I find Festool bits to be the best value, best quality and longest lasting on the market.

Nice bit
These bits work with the small centrotec chuck and swap out fast. Also, because of the hex shank, you don't have worry about spinning the bit in the chuck and galling the shank. Very handy for dirty conditions
