Makita B-49373 75 PC Metric Drill and Screw Bit Set

Why I reached for this kit

I like having a single, compact case that covers most of the drilling and driving I do on site and around the shop. The Makita 75-piece set fits that role well: it’s a straightforward, metric-focused assortment that covers wood, sheet metal and light masonry, with enough driver bits to get through an install day without digging through multiple boxes.

What’s inside and how it’s organized

Makita’s layout is simple and logical. On one side you get driver bits—short “insert” bits for use with a holder and longer “power” bits that go straight into an impact or drill. The spread is practical:

• Phillips, Pozidriv, Torx, and slotted in both insert and power lengths
• A handful of hex power bits
• Titanium nitride–coated HSS twist drills from 1 mm up to 8 mm
• Brad-point wood bits from 4 mm to 8 mm
• Light-duty masonry bits for brick and block

The sizes land where I need them most for hardware, hinges, pilot holes, and basic fixings. It won’t replace a full drill index or a specialty masonry set, but it’s a true “grab-and-go” kit. The case is blow-molded plastic with positive latches and labeled rows; the bit strips pull out when you want to reorganize or restock.

Fit, finish, and bit quality

Makita’s driver bits in this set are better than I expect at this price. The machining is clean and consistent—Torx and Pozidriv especially seat snugly in fasteners and resist cam-out. Hardness feels well judged: not so brittle that tips chip at the first sign of a stubborn screw, but hard enough to avoid rounding after repeated use. The longer power bits are straight and run true; I’ve used the Torx and Pozidriv sizes in an impact driver with no twisting or premature wear.

The TiN-coated HSS drills are sharp out of the box with proper split points for general purpose work. The coating isn’t a miracle solution, but it does help with lubricity and edge life if you pair it with sensible speeds and a drop of oil in steel. I’ve hit mild steel flat bar, aluminum extrusions, and assorted brackets without burning the edges. The brad-point wood bits track straight and produce clean entry holes in softwood and hardwood; they’re ideal for pilot holes for furniture hardware and hinge screws.

As for masonry, the included bits are fine for occasional holes in brick or block with a standard drill. They’re not intended for concrete or hammer drilling; use a rotary hammer and proper carbide SDS bits when that’s the job.

Performance in real work

• Wood: The brad points cut cleanly with minimal tear-out, and the TiN HSS bits clear chips well up to 8 mm. For shelf pins, pilot holes for cabinet hardware, or running cable clips, this covers most wood tasks. If I need larger diameters, I switch to spade or Forstner bits—the set tops out at 8 mm.

• Metal: In mild steel, stepping up through 3, 5, 6, and 8 mm produced round, burr-minimized holes when I stayed in the right RPM range and used oil. The small 1–2 mm sizes are understandably fragile—treat them gently and avoid side loading. The TiN coating has held up well under moderate use.

• Masonry: I keep these for a couple of anchor holes in a brick veneer or block partition. In those cases, a non-hammer drill with steady pressure works. For anything structural or concrete, I reach for a hammer-capable tool and dedicated bits.

• Fastening: The driver assortment is genuinely useful. Pozidriv and Torx bits see most of my action, and they’ve maintained crisp corners. Phillips and slotted are there for legacy hardware. The hex power bits are convenient for set screws and furniture fasteners. A magnetic bit holder (included in my set) grips short insert bits securely and saves a lot of dropped screws.

Case and usability

The case is sturdy and takes knocks. It’s not the most compact 75-piece layout, but it protects the contents and lays everything out clearly. The molded retention is on the firm side; some pieces take a firm pull to remove at first, which I prefer over bits raining out when the case opens. I appreciate that the bit rails can be lifted out—handy when you want a strip of drivers in a pocket instead of the whole case.

Labeling is clear, and the “everything visible at a glance” approach makes it quick to grab what you need. For mobile work, I’d love a slimmer footprint, but it’s not a deal-breaker.

Durability and care notes

Any mixed set is a compromise, and a little technique goes a long way toward longevity:

• Keep RPMs appropriate to material; slow down and use cutting fluid in steel.
• Let the drills do the work—don’t lean on small diameters.
• Use the brad points in wood only; they stay sharper that way.
• Save the masonry bits for brick/block and non-hammer drilling.
• If you routinely need cobalt or black-oxide specialist bits for stainless or hardened fasteners, supplement this set rather than pushing it beyond its lane.

Over several months of real use, the drivers have held their edges, and the commonly used drill sizes are still sharp. I’ve only had one casualty: a 1.5 mm twist bit snapped after a clumsy side load—a reminder that the tiny sizes always deserve a gentle hand.

What it doesn’t cover

A few limitations are worth noting:

• Metric only: Perfect for most hardware I encounter, but if you work in mixed environments, you’ll want an imperial set alongside.
• Hole size ceiling: Drills stop at 8 mm. Bigger holes will need separate spade, auger, step, or hole saw solutions.
• Masonry is light-duty: Not for concrete, granite, or hammer drilling.
• No specialty bits: You won’t find cobalt drills, SDS shanks, or tamper-proof drivers here.

None of these are flaws so much as scope. This is a well-rounded general-purpose set, not a specialty kit.

Value

Considering the range of tasks it covers, the consistency of the driver bits, and the respectable performance of the TiN drills, the Makita 75-piece set represents strong value. It’s priced like an all-in-one starter but performs like something I’m comfortable using professionally for everyday tasks.

If you already own a deep, dedicated drill index and a separate driver bit kit, you may not “need” this. But if you want a single case that covers 80% of the small holes and fasteners in a typical day, it’s hard to argue with the utility here.

Recommendation

I recommend the Makita 75-piece set for anyone who wants a compact, metric-focused kit that capably handles common drilling and driving tasks across wood, metal, and light masonry. The driver bits are precisely machined and hold up well, the TiN-coated drills stay sharp with proper technique, and the case keeps everything organized without fuss. It won’t replace heavy-duty masonry gear or specialist metalworking bits, and it tops out at 8 mm, but as a reliable everyday companion for installs, repairs, and shop projects, it earns its spot in the bag.
