Festool 493539 Fastfix Depth Stop Chuck
Key Features Repeatable Screw Depth The Festool 493539 FastFix Depth Stop Chuck is built to set screw depth consistently, even when material density changes. That means fewer proud screws, fewer blown-out surfaces, and less time fixing mistakes. FastFix Quick Change Swap between drilling and screwdriving in seconds on Festool drills with the FastFix interface. It adds dedicated drywall-style control without carrying a separate single-purpose tool. Quick-Out Ring The green quick-out ring backs screws out without changing your depth setting. That is a real time-saver when you need to correct placement and keep working. Overview The Festool 493539 FastFix Depth Stop Chuck is a depth stop chuck made for controlled screwdriving with compatible Festool drills. This is a depth stop chuck designed for driving screws to a consistent flush depth in materials like drywall, decking, and cabinet parts. Model Number: 493539. If you want cleaner results without constantly chasing clutch settings, this attachment is the whole point. What makes this accessory useful is not just that it drives screws, but that it keeps the screw depth consistent regardless of material density. Festool calls out an integrated clutch that maintains fastener placement depth independent of the drill's torque setting. In plain terms, once you dial it in, you can stop babysitting the tool and focus on the run of screws in front of you. The FastFix interface is the other big reason this accessory matters. Instead of carrying a separate dedicated drywall gun, you can switch from drilling to controlled screwdriving in seconds on compatible Festool drills. That saves time on punch-list work, light drywall jobs, deck work, and cabinet installation where you may be drilling pilot holes one minute and sinking screws the next. Festool also built this attachment with a narrow tip for a clearer view of the screwdriving area. That sounds simple, but it matters when you are trying to land a fastener cleanly on a line, hit a tight corner, or avoid marring a finished face. Better sightlines usually mean straighter starts and fewer slips. Another practical detail is the green quick-out ring. If a screw needs to come back out, you can reverse it without losing your depth setting. That is useful when a screw starts off-line, catches a hidden edge, or just needs to be reset. You are not starting from scratch every time you make a correction. Compatibility is centered around Festool's FastFix system. Source data lists this depth stop chuck for Festool drills with a FastFix holder or interface, including CXS/TXS 12, CXS/TXS 18, TPC 18/4, TDC 18/4, C 18, T 18, plus existing and previous model Festool drills equipped with FastFix such as T+3, C12, TDK, TDD, and CDD models. The main takeaway is simple: if your Festool drill uses the FastFix interface, this attachment is meant to expand what that drill can do. Who should buy it? Drywall installers, remodelers, finish carpenters, cabinet installers, and deck builders will get the most from it. It also makes sense for serious DIY users already invested in Festool cordless drills who want more precise screw placement without buying a separate drywall screw gun. If you do a lot of repeated fastening where flush depth matters, this is the smarter attachment than relying on feel alone. Set Screw Depth Once This attachment is made for repeated fastening where you want the screw to land at the same depth every time. On decking and other visible work, that means a cleaner finished surface and less rework. Designed for consistent, precise depth setting Helps maintain screw placement depth even as material density changes Work Like a Dedicated Screw Gun Without Carrying One If you already run a Festool drill with FastFix, this is a compact way to get better screwdriving control without adding another full-size tool to the bag. It is especially handy when the job bounces between drilling and fastening. FastFix interface allows quick tool-free chuck changes Lighter and more compact than carrying a separate dedicated drywall gun See the Fastener and Correct It Fast The narrow tip gives you a clearer line of sight to the screwdriving area, which helps when placement matters. And if you need to back a screw out, the quick-out ring lets you do it without losing the depth setting you already dialed in.
