5mm Spare Drill Bit for Countersink Bit

Functions

A replacement 5mm carbide drill bit for the Festool Centrotec countersink-with-depth-stop bit. The carbide construction holds an edge longer than standard high-speed steel bits — important for production drilling in hardwoods, MDF and engineered timber where standard bits dull quickly under load. Use this spare bit when the original wears or breaks. Countersink-with-depth-stop bits do real work in cabinet construction — dozens of fixings per cabinet, hundreds per kitchen — and the carbide tip is what keeps the cut clean through the volume of holes a working production shop drills in a week. The Centrotec interface allows the bit to be swapped without keying or chucking. A genuine Festool carbide replacement, ground to the countersink bit specification. Cabinetmakers, kitchen installers and joiners who do high-volume fixing work choose the carbide version of the bit because the longer working life pays back in fewer bit changes, more consistent hole quality, and the simple fact that a $71 bit that lasts twice as long as a $30 bit is the better economic choice over the life of the project.
