Key Features
36 Pieces, One CaseYou get a complete Festool storage and bit setup with an attic lid Systainer plus three organized cassettes. That keeps common drilling and fastening pieces in one grab-and-go box instead of loose in a drawer or mixed in a pouch. Fast Visual OrganizationThe transparent attic lid lets you see small parts and accessories at a glance, and the adjustable dividers let you lay it out the way you work. Less digging around means less wasted time on installs and punch-list work. Built for Drill/Driver WorkThis Festool drill/driver bit set is set up for clean drilling in wood-based materials and everyday fastening in wood, metal, and plastic. Short drill bits help when space is tight or when you are using an angle attachment.
Overview
The Festool SYS3 DF M 137 Attic Lid Systainer with 36-Piece Drill/Driver Bit Set is a modular storage and accessory kit built for organized drilling and fastening. This is a drill and driver bit set designed for jobsite organization, wood drilling, and everyday fastening. If you want your most-used bits and drills packed in a case that actually keeps them visible and easy to grab, this setup makes a lot of sense. The product is sold under variant SKU Systainer Bit Set M137 and combines the Festool attic lid Systainer with three bit and drill bit cassettes.
What makes this kit useful is not just the piece count. It is the way the pieces are stored. The transparent lid compartment gives you a quick top-down view of small parts and accessories, so you are not opening multiple boxes just to find one bit or driver. Festool also gives you adjustable partitions in the lid compartment, which means the layout can be changed to suit long drill bits, saw blades, bits, or small hardware depending on the job.
The included cassettes are where this setup gets more practical. You get an 18-piece drill and driver bit cassette for drilling in wood, glued solid wood, medium-density fiberboard, and acrylic glass, plus a 6-piece 100 millimeter driver bit cassette and a 12-piece 50 millimeter driver bit cassette for fastening work. Festool states the short drill bits are ideal for use with angle attachments, which matters when you are working inside cabinets, near corners, or in other tight install spaces.
Festool also put some thought into service life. The drill bits are made from high-alloyed ball bearing steel, and the drill geometry uses a center point and two cutters for quick, clean holes. Festool also calls out two chamfers instead of pre-cutting blades, which helps extend usable life, especially when drilling laminated chipboard. On the driver side, the bit tips are chemically nickel-plated and chrome-coated for longer wear and better corrosion protection.
From a storage standpoint, this is clearly built around the Festool system. The attic lid Systainer is compatible with the entire Festool Systainer system and can be integrated into bott vehicle equipment for transport. The lid compartment is designed to fit BKS SYS3 bit cassettes and drill bit cases, and Festool notes that the internal dimensions match Systainer3 M models, which can help if you already own inlays or other system components. That kind of compatibility matters if your van, shop, or trailer is already organized around Systainers.
This kit is a strong fit for cabinet installers, finish carpenters, remodelers, punch-list crews, and serious DIY users who care about staying organized. It is especially useful for furniture assembly, kitchen fitting, fitting installation, door and window installation, and general screwdriving in wood, metal, and plastic. It is not a powered tool, and Festool notes the Systainer is supplied without a machine insert, so the value here is in the storage system and accessory organization rather than tool storage for a specific machine.
If you are already in the Festool ecosystem, this is the kind of kit that keeps your daily-use drilling and fastening accessories from turning into a mess. If you are not, it still works as a clean, durable way to organize bits and small parts, but the biggest payoff comes when you use it as part of a larger Systainer setup.
Keep Bits Organized and Ready
This setup is about cutting clutter, not just adding another case. The attic lid keeps small parts visible, and the removable cassettes keep your drilling and fastening pieces grouped by task so you can move faster on installs, assembly work, and service calls.
