Bosch 5-Piece Multipurpose Drill Bit Set

Why I reached for this set

Running cable drops and setting light-duty anchors rarely happen in just one material. I’ll hit brick on one wall, grout on the next, then a sill plate or a steel bracket. That’s exactly the kind of day that had me grab the Bosch multipurpose bit set and leave the rest of the bit roll in the truck. I used the 1/4-inch and 3/16-inch sizes in an impact driver for anchors and pass-throughs, and I didn’t feel like I was compromising just because I wasn’t carrying a hammer drill or a metal-only twist bit.

Bosch positions these as true multi-material bits that can live in an impact driver, and that’s the use case where they won me over. They’re not aimed at specialty tasks like cabinet joinery or production fab work—more the “jobsite reality” of mixed substrates and limited trips to the toolbox.

What you get

The set covers five diameters: 5/32, 3/16, 1/4, 5/16, and 3/8 inch. Each bit has a 4-inch working length and a 6-inch overall length, with tungsten-carbide cutting tips, a multi-grind head, and steep flutes with raised ribs. The shanks are 1/4-inch hex, impact-rated, and still fit fine in a standard three-jaw chuck. It all lands in a compact plastic case that’s easy to toss in a bag.

The size range makes sense for anchors, tap-cons, and general utility holes. If you regularly drill larger than 3/8-inch, you’ll need something else; this set isn’t trying to be that.

Design that makes a difference

Three design choices stood out in use:

• The “no-skate” geometry at the tip starts noticeably cleaner on metal and glazed surfaces than typical masonry bits. I could start a hole in painted steel without a center punch if I had to, though I still recommend marking for accuracy.
• The steep, ribbed flutes move dust and chips out well. In masonry, this translates to less pecking to clear debris and fewer stalls. In metal, it helps curl and eject chips reliably as long as you keep the feed steady.
• The impact-rated hex shank is the right call. Swapping sizes from a pouch is quick, and the bits seat positively in impact drivers without cam-out. In a drill/driver they run true without wobble.

Masonry performance

In brick, mortar, and standard concrete block, these bits are genuinely quick. I made a string of 3/16-inch anchor holes in brick with an impact driver (no hammer action) and didn’t feel outgunned. The bit tracked true, produced consistent dust, and didn’t require excessive pressure. In denser concrete, a hammer drill still shortens the job, but the bits themselves keep up either way.

The biggest difference compared to off-the-shelf masonry bits I’ve used is the hole start and the steady progress through aggregate. With the Bosch bits, progress felt less “crunchy” and more continuous, even when I hit small pebbles. Dust evacuation is strong; I still recommend a quick blow-out and vacuum for deeper holes, but I wasn’t stopping every half-inch to clear things.

If you encounter rebar mid-hole, these will nibble through mild steel with patience, but I prefer stopping to switch to a dedicated metal bit to preserve the cutting edges.

Metal performance

Multipurpose bits often underwhelm in metal; these didn’t. I ran 3/16 and 1/4-inch holes through 1/8-inch angle iron and 3/16-inch flat bar using a drill/driver at moderate speed with a dab of cutting fluid. Starts were controlled with minimal walking, and the chips formed properly—no dusting or burning. Hole quality was round and within a few thousandths for bolt-fit work.

They’re not a replacement for cobalt twist bits when you’re drilling dozens of holes in heavy plate, but for on-site brackets, strut, and small repairs, these were faster than I expected and stayed cool with reasonable technique. Keep the RPMs down, feed steadily, and use lubricant; you’ll extend life noticeably.

Wood and plastics

In wood, these behave like sharp high-angle twist bits. They aren’t brad-points, so for furniture-grade plugs you’ll still want dedicated bits, but for studs, blocking, and plywood they cut cleanly and clear chips fast. I saw minimal tear-out on exit when I backed the work or eased up near breakthrough.

In plastics, slow speed is key. I drilled acrylic and PVC with light pressure; the flutes kept chips moving without melting. As always, back the work and let the bit do the cutting.

Tile and delicate surfaces

On ceramic wall tile, the no-skate tip earns its keep. I started with painter’s tape anyway out of habit, but the bit didn’t wander and produced a neat hole at low RPM and light pressure. Porcelain is trickier—possible, but slow. Mist cooling helps. If your day is full of porcelain holes, a dedicated spear-point or diamond solution will be more efficient and gentler on the glaze.

Durability and wear

After a long afternoon across brick, wood, and some light steel, the cutting edges still felt crisp, and I didn’t see chipping at the carbide tips. The multi-grind geometry seems to spread the work across the edge well. As with any carbide-tipped bit, once they dull, at-home sharpening isn’t really practical. Technique matters: avoid overheating in metal, clear dust in masonry, and don’t slam into rebar.

Ergonomics and compatibility

The 1/4-inch hex shank makes a lot of sense on a service call. I appreciated quick changes from a belt holster into an impact driver with no chucking and unchucking dance. In a standard drill chuck, the bits run true and don’t spin under load. The plastic case is compact and keeps sizes easy to grab, though there’s no extra room for add-ons beyond the five included.

A note on tool pairing: these are fine in an impact driver for most light-to-medium work. If you’re facing dozens of holes in poured concrete, pair them with a hammer drill. They are not SDS-plus rotary hammer bits; that’s a different category.

What could be better

• The set tops out at 3/8-inch. Common enough, but 7/16 or 1/2-inch options would cover more anchor styles without a separate purchase.
• The 4-inch working length is versatile, yet occasionally just shy for deeper masonry passes. A companion “long” version would be welcome.
• In fine woodworking, these won’t replace brad-points for clean entry holes, nor Forstners for flat-bottom work.

None of these are deal-breakers; they’re more about knowing the intent of the set.

Who will benefit

• Electricians, low-voltage installers, and facilities techs who bounce between materials and value staying on an impact driver.
• DIYers tackling mixed-material projects where a single set can handle anchors, brackets, and pass-throughs without swapping to task-specific bits.
• Pros who want a reliable “house set” in the pouch while keeping specialized bits in the truck.

If your work is heavy structural concrete, precision metal fab, or high-end cabinetry, treat these as a complement, not a replacement.

Bottom line and recommendation

Bosch claims longer life in multi-material use and faster drilling in metal; my time with the set aligns with those promises. The bits start cleanly, clear chips well, and hold up across brick, concrete, wood, and mild steel. Being able to run them confidently in an impact driver is a genuine productivity win, and the hex shank/geometry combo feels well thought out rather than gimmicky.

I recommend this set as a dependable, grab-and-go solution for mixed-material tasks. It won’t replace your SDS bits, cobalt drills, or brad-points where those shine, but it reduces the number of times you need to reach for them. For service work, remodel punch lists, and everyday jobs where material changes from hole to hole, the Bosch multipurpose bit set earns a spot in the kit.
