Bosch 5-Piece Multipurpose Drill Bit Set

Why I reached for this set

A lot of my workdays zigzag between materials—brick for anchors, metal brackets, wood blocking, and the odd tile backsplash hole. Swapping between dedicated bit types slows the job down. That’s why I kept this Bosch multipurpose set in my impact driver kit for a month. The promise is simple: one set that drills most common materials without changing chucks or chasing specialty bits. After living with it across jobs, it’s earned a permanent spot in my bag—with some caveats you should understand.

What you get

• Five carbide-tipped bits with hex shanks: 5/32, 3/16, 1/4, 5/16, and 3/8 inch
• Working length: 4 inches (6 inches overall)
• Plastic case with dedicated slots

The size spread covers typical pilot holes for Tapcons, wall anchors, and through-holes for light hardware. There’s no 1/2-inch bit in the set, so plan accordingly if you need larger diameter anchors or conduit fittings.

Design details that matter on site

• Hex shanks: These are impact-rated and lock into an impact driver without slipping. They also seat well in a standard three-jaw chuck.
• Multi-grind carbide tips: The geometry is designed to cut both brittle materials (like masonry and tile) and ductile ones (like mild steel and wood).
• Steep flutes with ribs: They clear dust and chips faster than typical straight-flute multipurpose bits, especially noticeable in brick and block.
• “No-skate” tip: It isn’t magic, but it does a better-than-average job reducing wander on smooth surfaces.

All of that adds up to a bit that’s as comfortable in an impact driver as it is in a hammer drill/driver, which is rare for multipurpose sets.

Performance across materials

Masonry (brick, block, mortar, light concrete)
- With an impact driver and no hammering, these bits cut brick and block cleanly and quickly. For Tapcon pilots in 3/16 and 1/4 inch, I had reliable progress without switching tools.
- In a hammer drill/driver on hammer mode, dust flushed well and heat stayed in check for small hole counts. Concrete is where these shine compared to generic “all-purpose” bits that tend to burn and glaze.
- On cured, dense structural concrete, they’ll do the job for small anchors, but nothing beats SDS-Plus masonry bits for speed and longevity in heavier workloads.

Metal (mild steel, sheet, and bracket stock)
- The multi-grind carbide point bites into mild steel better than I expected from a multipurpose profile. In 1/8-inch steel bracketry, the 1/4-inch bit tracked straight with minimal chatter.
- Keep the drill on low speed, add cutting fluid, and avoid hammer. The no-skate tip reduces the need for a center punch, but I still recommend a light punch for accuracy and clean starts.
- I wouldn’t use these on hardened steel or stainless beyond thin sheet—dedicated cobalt or carbide metal bits are better for that.

Wood and PVC/plastic
- No issues in studs, plywood, or PVC. They won’t leave a brad-point-clean entry, but tear-out was minimal on both faces when backing the exit side. If you need cabinet-grade holes, switch to a brad-point bit.
- The hex shank makes bit swaps fast when alternating between wood framing and masonry anchors.

Tile
- Pilot holes through standard ceramic tile were controlled and clean with painter’s tape and light pressure. Do not use hammer mode on tile. These are not glass/tile spear-point bits; they still work, but technique matters: low speed, no percussion, let the carbide do the work. For porcelain or glass tile, a dedicated tile bit is safer.

Speed and accuracy

Bosch claims big gains in metal speed and multi-material life. I can’t quantify their exact percentages, but I can say this: compared to the mixed bin of generic masonry and HSS bits many of us keep for “whatever comes up,” these are meaningfully faster and start straighter. The nose geometry earns its keep when you’re trying to hit a precise anchor location on a glazed brick or painted metal surface.

The “no-skate” behavior isn’t a substitute for good technique. On painted steel doors and prefinished surfaces, I still like a quick center punch to guard against cosmetic scuffs. But I had noticeably fewer walk-offs than with conventional masonry bits.

Durability and heat management

Carbide tips hold up well if you avoid the two big killers: heat and side loading. Across several dozen holes in brick, block, and mild steel, the cutting edges stayed sharp, and the flutes didn’t pack out as quickly as I expected. A few care tips that made the difference:

• In metal, run slow, use fluid, and peck to clear chips.
• In masonry, let the bit do the work—don’t lean on the drill. Use hammer only in appropriate materials.
• Avoid twisting the bit to lever out plugs; back the bit out to clear debris instead.

I did see some edge micro-chipping after a session that included accidental contact with rebar inside a block wall. The bit finished the hole, but I wouldn’t make rebar drilling a habit. If you hit steel inside concrete, turn off hammer, lower speed, and add oil; then resume hammer only when you’re past the steel.

Case and organization

The plastic case is compact and holds the five sizes securely. The size markings on the shanks are legible but can get dusty; I’d love a higher-contrast etch or color banding for quick ID. The case only accommodates the included five—there’s no extra slot for a 1/2-inch add-on. The latch is positive and hasn’t opened accidentally in my bag.

Where these bits fit in a kit

• Power users who live in concrete all day should stick with an SDS-Plus rotary hammer and dedicated masonry bits.
• Cabinet installers and finish carpenters who need spotless holes in hardwoods will prefer brad points and forstners.
• Electricians, plumbers, HVAC techs, facility maintenance, remodelers, and serious DIYers benefit most from this set. If your jobs mix materials and you want to run almost everything out of an impact driver, it’s a very practical solution.

Limitations to keep in mind

• Working length is 4 inches. That’s ideal for most anchors but may be short for deep-set fixtures or thick assemblies.
• No bit larger than 3/8 inch. If you frequently drill 1/2-inch holes, plan for a separate option.
• Tile performance is good with technique on standard ceramic. For porcelain or glass, use dedicated tile/glass bits.
• Not intended for hardened steels; use cobalt or solid carbide for those tasks.

Practical tips for best results

• Impact driver: Great for brick, block, wood, and plastic. Turn off any “assist” modes that pulse aggressively when starting on smooth materials.
• Hammer drill/driver: Use hammer in masonry only. For metal and tile, drive in drill mode at low speed.
• Marking: A light center punch on metal and a strip of painter’s tape on glossy tile improve starts.
• Dust control: In masonry, peck drill and clear flutes often; a vac makes a noticeable difference in speed and bit life.

The bottom line

This Bosch multipurpose set has become my default for small to medium holes across mixed materials. The hex shanks make it truly impact-driver friendly, the carbide tips hold up under normal jobsite abuse, and the flute design clears debris better than most multi-material bits I’ve used. It won’t replace specialized bits for heavy concrete, pristine woodworking, or tough alloys—but that’s not the goal.

Recommendation: I recommend this set for anyone who frequently moves between materials and wants to carry fewer bits, especially pros and DIYers who rely on an impact driver. It saves time, starts cleanly, and drills fast enough that I reach for it first. If your work is mostly heavy concrete or precision cabinetry, pair it with dedicated bits for those tasks and keep this as your go-to for everything in between.
