Bosch 34-piece Drilling and Driving Mixed Set

I tossed Bosch’s 34‑piece mixed set into my drill bag for a month and used it everywhere a homeowner or light-duty pro might: hanging shelves, assembling cabinets, setting small anchors in brick, and knocking out the odd pilot hole in mild steel. It’s a compact, no-drama kit that covers the fundamentals of drilling and driving in wood, light metal, and masonry without taking up much space.

What you actually get

This is a true mixed kit, not just driver bits sprinkled around a couple of drill sizes. You get:
- Black oxide twist drills: 1/16 in (×2), 1/8 in, 5/32 in, 3/16 in
- Brad point wood bits: 1/8 in, 3/16 in (×2), 1/4 in, 5/16 in
- Rotary masonry bits: 5/32 in, 3/16 in (×2), 1/4 in, 5/16 in
- Driver bits: Phillips (#1, #2, #3), Pozidriv (#1, #2, #3), Slotted (#4, #6, #7), Torx (T15, T20, T25, T30)
- Accessories: 2.5 in bit holder, three nut-driving sockets (3/16, 5/16, 3/8), a 1/4 in hex socket adapter, and a countersink bit
- Storage: a hard plastic clamshell case with labeled positions

The spread is sensible. You can pilot and countersink for most wood screws, switch to brad points for clean-faced joinery, and use the masonry bits for light anchor work. The driver selection hits the basics—including Pozidriv, which is a quiet lifesaver on European cabinet hardware and some electrical screws.

Drilling in wood: clean and predictable

For most carpentry tasks, I reached for the brad point bits. They start precisely, especially on slick melamine and plywood, and they produce clean exit holes with minimal tear-out. In 3/4 in birch ply, a 1/4 in brad point left a crisp rim with almost no fuzz on the backer when I used a scrap support and moderate feed pressure. Dimensional SPF studs were even easier—fast chips, straight holes, and no wandering when drilling on center marks.

The included countersink pairs well with the brad points. It’s a straightforward, fixed-flute style that chamfers consistently; it won’t replace a dedicated depth-stop countersink for furniture work, but for sinking screw heads flush in casing, trim, and shop projects, it’s exactly what I expect in a compact kit.

Drilling metal: fine for light duty

The black oxide twist drills are appropriate for aluminum, thin mild steel, and general-purpose pilot holes. I tested the 1/8 in and 3/16 in bits on 1/8 in mild steel angle using cutting fluid and conservative RPM; both cut cleanly and stayed reasonably sharp across a handful of holes. They are not cobalt or titanium nitride bits, and they’re not meant for stainless or repeated heavy use. If you routinely drill thicker stock or hard alloys, you’ll quickly outgrow this portion of the set. For household tasks—pilot holes for hardware, drilling through light-gauge brackets—they’re fine.

Masonry and anchors: stick to light materials

The rotary masonry bits handled brick and mortar well with a standard drill/driver on hammer mode. I used the 5/32 in and 1/4 in sizes to set plastic anchors for shelving standards and hose reels in clay brick; dust cleared easily and holes stayed on size. In poured concrete, they’ll get the job done for shallow anchors, but expect slower progress and more heat. These are conventional masonry bits, not SDS-plus and not designed for heavy repetitive anchoring in structural concrete. It’s also worth noting the smallest masonry bit is 5/32 in; if you need tiny tap holes in brittle tile or specialized anchors, you’ll need to add to your kit.

Driving performance and bit quality

The driver assortment is practical. Phillips #2 fits snugly in common construction screws; the #3 is useful for larger deck and structural screws that often get mangled by a too-small bit. Pozidriv support stands out—I used the PZ2 on Euro hinges and cabinet screws with markedly fewer cam-outs than a Phillips. Torx T25 and T30 covered deck screws and ledger screws without issue.

Bit hardness feels dialed for a drill/driver rather than an impact driver. I used them in both, but if you live on an impact driver and drive hundreds of screws a day, a dedicated impact-rated set will last longer. For weekend projects and punch lists, the edges held up well and the fit in fasteners was positive, with limited wobble when used with the included magnetic bit holder.

The three nut-driver sockets and the hex adapter are a nice touch. The 5/16 in socket handled self-drilling roofing screws on a shed door install, and the adapter’s detent holds them securely. No, it’s not a replacement for a ratcheting nut driver or a 1/4 in mechanic’s set, but it filled a few gaps without sending me back to the toolbox.

Case and organization

The hard case is compact and easy to toss into a tool bag. Labels are clear, and everything has a designated slot. The latches are firm enough, though smaller pieces can work loose if the case is tossed around in a truck. I wouldn’t call it ruggedized—think organized transport rather than jobsite abuse. I ended up adding a small strip of foam over the driver bits to keep them perfectly seated; not required, but it kept things tidy in my workflow.

What’s missing and what I’d change

No compact kit ticks every box, and a few omissions stood out:
- Drill sizes: the black oxide range tops out at 3/16 in, so you’ll need separate 1/4 in and larger twist drills for metal. For wood, the brad points bridge that gap, but not if you need a larger pilot in metal.
- Pilot sizes: an intermediate 7/64 in or 9/64 in twist drill would better match common wood screw pilots. You can make 1/8 in work in many cases, but it’s not always ideal.
- Impact rating: the bits survive casual impact use, but if you rely on an impact driver exclusively, look for an impact-rated set for everyday driving.
- Tile and specialty: there’s nothing here for porcelain or glass; that’s outside the target, but worth noting.

Those are tradeoffs I expect at this size and price, and none were deal-breakers for general household and light-jobsite use.

Durability and value over time

After a month of regular use, the brad point tips still cut cleanly, and the most-used driver bits (#2 Phillips, T25, PZ2) show only modest wear. The black oxide bits dulled first—as expected—but remained serviceable after resharpening. The masonry bits show some abrasion on the carbide tips but still bite brick effectively. The case hinges and latches feel intact, and the bit holder magnet hasn’t loosened.

As a “grab one case and go” solution, the kit has saved me time. I haven’t needed to rummage for odd driver sizes, and I’ve completed light metal, wood, and masonry tasks without swapping kits. That convenience is the real value here.

Who it’s for

• Homeowners and renters assembling furniture, hanging shelves, mounting TVs, and tackling routine repairs
• DIYers who want a compact, organized set that covers wood, light metal, and brick without separate boxes
• Pros who want a glovebox, service-van, or punch-list kit to supplement specialized bits on the truck

Who it’s not for

• Trades drilling repeated holes in structural concrete or using SDS-plus systems
• Metalworkers who need cobalt or step bits and a full index beyond 3/16 in
• Heavy impact-driver users who churn through bits daily and need impact-rated accessories exclusively

The bottom line

The Bosch 34‑piece set is the sort of kit I like to keep within arm’s reach: thoughtfully curated sizes, clean-cutting brad points, genuinely useful driver variety (including Pozidriv and key Torx sizes), and just enough masonry capability to handle common anchors. It won’t replace a full drill index or a pro-grade concrete kit, and it isn’t the last word in impact durability. But as an everyday, do-most-things companion, it’s balanced, compact, and reliable.

Recommendation: I recommend this set as a well-rounded, affordable companion for general drilling and driving in wood, light metal, and brick. If your work centers on heavy concrete, stainless, or all-day impact driving, pair it with specialty kits. For everyone else who wants one case that handles 90% of household and light-jobsite tasks without fuss, this mixed set earns a spot in the bag.
