The Snappy 93258 1/8" X 1/4" Trim Screw Countersink is a dedicated countersink drill bit for drilling pilot holes and cutting a countersink for trim-head screws in wood. This is a countersink drill bit designed for trim screw fastening and finish work. Model Number: 93258. If you install casing, trim, decking, or other visible woodwork where screw placement needs to look clean, this bit handles the prep work in one step instead of making you switch between separate drill bits and countersinks.

The working end uses a 1/8 inch high speed steel twist drill paired with a 1/4 inch x 82 degree counterbore. In practical terms, that means you can drill a pilot hole and form the seat for the screw head at the same time. The 82 degree angle matters because it matches the head angle on most screws, so the screw seats properly instead of riding high or tearing out the edge of the hole. Snappy recommends it for #8 trim-head screws in hard wood and #10 trim-head screws in soft wood, which makes it a smart fit for the kind of detail fastening where clean results matter more than brute force.

What makes this one different from a generic countersink is the shank setup. The Festool Centrotec compatible shank is built for users running compatible Centrotec keyless chucks. If that is already your setup, this bit drops right into the system you are using instead of forcing you into an adapter workaround. That makes a difference when you are bouncing between drilling, fastening, and finish work and want quick changes without giving up control.

Snappy also built this trim screw countersink to be serviceable instead of disposable. The pilot bit can be adjusted or replaced by loosening the hardened set screw, and the listed replacement twist drill is part number 49208. That is useful on the job because the pilot drill is the wear item. When it eventually dulls, you can swap the drill instead of replacing the whole countersink assembly. The product description also notes compatibility with Snappy's Premium Rotating Stop Collar for more controlled depth work when you need repeatable screw seating in visible trim or decking.

This is best suited to carpenters, trim installers, cabinet and finish crews, deck builders, and serious DIY users who care about clean screw holes in wood. If you are working with Festool Centrotec compatible chucks and regularly install trim-head screws, the Snappy 93258 1/8" X 1/4" Trim Screw Countersink is the kind of small accessory that saves real time and makes the finished work look sharper. It is not a general-purpose masonry or metal bit. It is a purpose-built fastening accessory for wood applications where a neat countersunk result is the whole point.
