Bosch 103-piece Mixed Screwdriver & Titanium Drill Bit Accessory Set (wood, metal, masonry)
Product description
What it is and why you’d buy it
This Bosch 103-piece mixed screwdriver and drill bit accessory set is designed as a “one box for most jobs” kit. On paper, it covers drilling into wood, metal and masonry, plus a good spread of screwdriver bits for common screw heads. If you do DIY often (flat packs, shelves, small repairs, basic fencing work, general fixing around the house), having the right bit to hand can save more time than you’d think.
The set’s appeal isn’t just the quantity. It also includes extras that you typically end up buying separately: a hole saw in multiple sizes, a centring drill bit, flat wood spade bits, a universal bit holder, socket wrench bits, a countersink bit and an Allen key. It’s the sort of kit that suits homeowners and improvers who want coverage without building a collection bit-by-bit.
That said, it’s not perfect for everyone. Because this is a mixed kit with several bit types, you may still want specific specialist bits if your projects lean heavily into one material or one drilling style.
The essentials (what’s covered)
Drill bits are split by material, which is helpful because it gives you a practical path to choose the right type:
- Wood drill bits listed in sizes from 3 up to 10 mm.
- Metal drill bits listed in smaller increments, starting at 1.5 mm and running through to 7 mm.
- Masonry drill bits listed in sizes 4, 5, 6, 8 and 10 mm.
Screwdriver bits are also included in two lengths (25 mm and 50 mm) with multiple drive styles. For the 25 mm set you’ll find PH/PZ options, plus S, T and H sizes shown in the description. For the 50 mm set, the kit again covers PH/PZ with S and T sizes.
Accessories are a big part of the value here. Included are a hole saw set (32/38/44/54 mm), a centring drill bit, flat wood spade drill bits (16/22 mm), a universal bit holder, socket wrench bits (5/6/8/10/11/12/13 mm), a countersink bit, and an Allen key.
Where it stands out in use
If you’re wondering “what will I actually do with all this?”, it often comes down to the small, real-world jobs:
For example, when fitting a shelf, you might start by drilling into wall or masonry for fixings, then switch to the appropriate screwdriver bit to drive screws cleanly. In wood work, the spade bits and smaller wood drill sizes can be handy for neat through-holes for cables or for preparing runs.
For metal tasks, the kit includes metal drill bits, and the description specifically notes that using coolant is recommended when drilling in metal. That’s an important practical detail: if you tend to drill metal “dry” out of habit, you may find results vary.
Limits to be aware of before you buy
It’s a mixed accessory set, so it’s not the best choice if you’re expecting deep expertise in one niche. A specialist cabinetmaker’s selection or a dedicated metalworking set will usually be more focused.
Also, the “titanium” wording points to coating/finish on the drill bits, but the description doesn’t provide details like thickness of coating or performance comparisons. That means you should treat it as a general-purpose kit rather than something you’d choose purely for cutting-edge, laboratory-level drilling speed.
Finally, the masonry bit sizes listed are limited to 4, 5, 6, 8 and 10 mm. If your projects consistently need a wider masonry range, you may still end up adding more bits later.

Who it suits (and who should skip it)
It makes sense if you want a mixed screwdriver and drill bit set that can handle wood, metal and masonry tasks in the same workflow. It’s also a good match if you value having “bit types” and a few specialised pieces (like hole saws and spade bits) without needing to buy separate packs.
You may want to skip it if you already own a decent range of drill bits and you only need one area covered (for example, you mainly drill one material and want a deeper, more uniform set). It might also not suit you if you’re doing frequent precision metal drilling and you want a more tightly specified selection.
Is it worth it?
This Bosch 103-piece mixed set is worth considering if your DIY tends to span different materials and you want the practical extras in the same box. The size coverage across wood, metal and masonry, plus the included hole saws, countersink bit and universal holder, points to day-to-day usability.
However, if your projects are heavily one-type (only masonry, only metal, or mainly fine screw driving), you’ll likely get more focused performance from a more specialised collection—so it can feel more “general coverage” than “mastery tool”. If you do buy it, it’s sensible to check that the masonry sizes and screwdriver drives you use most are actually listed in the ranges above, and to remember the kit’s note about coolant for drilling metal.
