The Snappy 93007 7/64" X 3/8" Countersink is a countersink drill bit made for drilling a pilot hole and cutting a countersink or counterbore for wood screws in one pass. This is a countersink drill bit designed for wood screw pilot drilling and clean screw seating. Model Number: 93007. If you use a Festool Centrotec setup and want a quick-change countersink that matches common wood screw work, this one is aimed right at that job.

The working end uses a 7/64 inch high speed steel twist drill paired with a 3/8 inch countersink at 82 degrees. In practical terms, that gives you the pilot hole and the screw head recess in the same cut, which speeds up repetitive fastening work and helps keep screw heads sitting flush instead of proud. The listed screw match is #6 in hardwood and #8 in softwood, so it fits a very common range of cabinet, trim, and general woodworking fasteners.

What matters here is system fit. The Festool Centrotec compatible shank is the real reason to buy this version over a standard countersink. If your drill or driver is set up around Centrotec keyless chucks, this accessory keeps changes fast and direct without adding another adapter into the mix. That is especially useful when you are bouncing between drilling, countersinking, and driving on finish work or assembly jobs where small delays add up.

Snappy also built this style of countersink to be serviceable. The pilot drill can be adjusted or replaced by loosening the hardened set screw, and the specified replacement twist drill is part number 49207. That matters because pilot bits are wear items. Being able to swap the drill instead of replacing the whole assembly helps keep the tool working accurately over time.

Material and build are straightforward and job-focused. The pilot is a high speed steel twist drill, and the countersink is precision machined with tight tolerances and made for long cutting life. The 82 degree countersink angle is also the standard detail many users care about because it matches the head angle of most common screws used in woodworking and light construction fastening.

This countersink is best suited to wood-focused work rather than metal fabrication. It makes the most sense for cabinet installers, trim carpenters, furniture builders, remodelers, and serious DIY users who predrill for cleaner results and less splitting. If you already own Festool Centrotec chucks and want a purpose-built wood screw countersink instead of a generic bit, the Snappy 93007 7/64" X 3/8" Countersink is the practical choice.
