Key Features
Overview
The DeWalt Maxfit Ultra Screwdriving Set 50-Piece, model DWAUMF50SET, is a screwdriving bit set built for fastening with drills and impact drivers. This is a screwdriving bit set designed for driving common fasteners across wood, sheet metal, PVC, drywall-related work, and general repair jobs. If you want one case that covers the bit styles most people actually reach for, this set makes sense.
What matters here is not just the piece count. DeWalt built these bits around impact use, with an anti-snap design intended to reduce bit breakage and improve durability under repeated fastening. The precision fit tip is there for a practical reason: better engagement in the screw head means less cam-out, less stripped hardware, and less pressure on your wrist when you are driving overhead or in awkward positions.
The set covers a wide mix of common screwdriving profiles, including Phillips, square, slotted, and Torx, plus a 3/8 inch socket adapter, two nut drivers, and a 3 inch locking bit tip holder. That mix gives the set broader jobsite value than a basic bit pack. It can handle cabinet screws, framing hardware, light metal fastening, electrical boxes, HVAC screws, and assorted maintenance work without forcing you to grab a second case.
DeWalt also paid attention to day-to-day usability. Each bit has a laser-engraved size marking so you can sort and replace the right piece faster. That sounds minor until you are working from an open case on the floor or in the back of a van. The included Tough Case+ is connectable for custom storage setups, which is useful if you already organize accessories by task and want this set to fit into a larger system.
From a design standpoint, the 1/4 inch hex shank keeps the DeWalt Maxfit Ultra Screwdriving Set 50-Piece compatible with standard impact drivers and drills that accept hex accessories. The steel construction is straightforward and appropriate for this category: durable enough for repeated fastening work without overcomplicating what should be a grab-and-go accessory set.
This set is a good fit for electricians, HVAC techs, maintenance crews, remodelers, installers, punch-list pros, and serious DIY users who need a reliable assortment instead of a drawer full of random loose bits. If your work regularly jumps between screw types and you care about staying organized, the DWAUMF50SET is the kind of set that earns a permanent spot in the truck.

Tool Nut's Take
DeWalt Maxfit Ultra Screwdriving Set 50-Piece is the kind of set you keep in arm's reach
This is a smart buy for anyone who does real fastening work and wants broad coverage without carrying three separate bit packs.
- Who it's for: Pros and serious DIY users who bounce between Phillips, square, slotted, Torx, and nut-driving tasks in the same day.
- Why it stands out: The mix is practical, the bits are impact rated, the precision-fit tips help reduce cam-out, and the Tough Case+ is actually useful instead of being throwaway packaging.
- Worth knowing: This is an accessory set, not a specialty fastener kit. If you mostly use one drive style, a dedicated pack may be cheaper, but for service work this assortment is hard to argue with.
Common Questions
- Is this set for impact drivers or regular drills? Both. The 1/4 inch hex shank is impact rated for use in impact drivers and also works in drills that accept hex-shank accessories.
- What bit styles are included? The set includes Phillips, square, slotted, and Torx screwdriving bits, plus nut drivers, a socket adapter, and a locking bit holder.
- Does the case work with other DeWalt storage cases? It is packed in the connectable Tough Case+ system for custom storage setups, with additional cases sold separately.
- Is this a single bit or a full set? It is a 50-piece set, not an individual bit.
