Description of SNAPPY 4 Piece Countersinking Festool Centrotec

According to my experience, this set has significantly increased my productivity in drilling and countersinking. The Centrotec system is super easy to use and swap bits and the quality of the bits is top-notch. The set includes 4 different sizes which have covered all my drilling needs. The only drawback is that the set is slightly pricey, but it's definitely worth the investment for its exceptional quality.
Pros
Easy and quick countersinking with Festool Centrotec system
Cons
Requires additional investment for Festool Centrotec system compatibility
Typical good quality snappy tools. My only criticism is Festool refusing to provide a 1/4" quick change hex chuck, forcing me to buy double drill bits and countersinks for my Festool drill bits.
Pros
Reduced runout and maximum torque transfer between drill and bit
As I replace some wear parts I try to buy Centrotec compatible parts as I am a fan of Festool and Snappy. is one of the Few suppliers of such tools outside of Festool These countersinks are very good quality and will do what I need to replace the old 1/4" bits I had to remove. I'm not very happy with the #2 square drill bit as it seems to have slightly compromised the fit of the McFeeley fasteners I've been using. I already had two of these and they have the same incompatibility.
Pros
Includes 3" Precision Milling Screwdriver with Hardened Square Bit #2
