Choosing the Right Drill Bit for Brick Walls in Garage: Concrete vs Other Types

geforc 32004 47
Best answers

What drill bit should I use for drilling holes in brick garage walls for shelves so the holes stay the right size?

Use a carbide masonry/concrete drill bit (widia); with an SDS-Plus drill, use SDS-Plus masonry bits, and drill brick slowly with only light impact or no impact on softer/older brick rather than forcing it. [#17162116][#17162798][#17162869] For better accuracy, start with a smaller pilot hole and then enlarge it to the final diameter, which also helps if you hit a joint. [#17162798][#17162869][#17163442] If the wall is hollow brick, the hole can easily become oversized, so match the plug/anchor to the wall and, if needed, drill a smaller hole first or choose a larger plug. [#17162869][#17162884] If the drill wanders and makes an oversized hole even with a good bit, check for side play in the chuck/tool holder, because wear there can make the bit cut too large.

    Hello, gentlemen, it is simple drilling, but I have a problem, I have brick walls in the garage and I have to drill a few holes for the shelves. I was drilling today without hammering with a concrete drill bit and instead of a 6mm hole it got blown 8 or better. I have never drilled in brick, from what I have read you can not drill with a hammer, but what drill bits to choose? typical for concrete? everyone writes or says something else. What do you advise?

    A normal concrete drill bit. The so-called drill widiowe has such "wings" at the end, to put it this way. Measure the diameter of the drill bit on these wings, not on the chuck.

    JCB is a brand of some market? Because I know it about construction machines, but not about drills. What kind of brick is it? White, red, clinker? Sometimes a stone can be found in the bricks, then the drill will "come off". And of great importance is a good perpendicular, safe guidance.

    You can drill with hammer in bricks only in moderation. If someone denies using the maximum power of the drill, it may be uninteresting.
    It is safest (especially in building materials) to use the so-called pre-drilling. We use a drill with a relatively small diameter. If the nominal hole is to be 10mm, first use the fi-5 drill. Later, you can perform main drilling, but also without rush, if you want precision.

    I do not drill professionally, but I agree with the previous speaker. I drill without impact, with small turns, the brick goes easily, so there is no point in drilling at full speed with strong pressure. However, when we hit a stone, it has to go down ...

    I was drilling 4 holes and every time it twisted and it made a big hole. It is a red brick, probably some old one, because they are old garages. I'd be pissed if there were holes in the house, but in the garage it doesn't bother, although it pisses me off that I can't drill and hang stupid shelves normally. Maybe I will ask differently, which drill bits do you recommend, which company? at most I will buy and then I will try.

    Cheap and for me as an amateur, Leroy Merlin and Dexter are good.

    Or Irwin, most stores can be bought

    In concrete, it also happens when you drill with a "made-to-measure" drill, it is 1/4 of the oversize.
    Drill with smaller drill bits and only at the end with the dimensional one.

    In my opinion, Irwin. I have drill bits from this company from a purchase much earlier (maybe 15 years ago) when I was making a dozen or so holes in the bathroom tiles. The 6 and 8 mm drill bits went without any problems and even in red-bricked brick. The fact is that at that time I was using mechanical impact (drilling in brick - for glaze without impact). The holes were perfect. Dexter - I didn't use drills.

    Gentlemen, one thing is simple drill bits, but as already written, drill with a small one and then ream it.
    As for the quality of drills, I have an example, I had to screw the toilet at home, 4 bad drills went, I went, I bought an expensive set, the same drill, and I use it as an amateur to this day.
    As my experience, I can say that I used to work at TPSA for 13 years as a drill fitter constantly on the move.
    I recommend Hilti

    I can add that drill bits are good that keep this widia tip where we still expect it after drilling is finished. Nothing has changed here, unfortunately :D
    I hit my answer right after my friend.
    I can honestly write that it all depends on the so-called expectations, because if a colleague is going to fight hard sometimes, it is worth focusing on the quality of proven producers. With very occasional adventures with drilling, chiselling and other construction work - I would also buy cheap, BUT! continuously: being aware of this during operation.
    Okay - I read it with understanding and keep writing :D
    It is like buying a set of keys with this and that. Does it pay off or not?
    Well, but I already have such keys. Well, but the others will never be of any use to me. Well, when it turns out that the big one can help ...
    The colleague himself sees that no one colleague is able to advise one hundred percent on such a matter. I write honestly and I hope that my friend will not hold it against me.

    Well, but I read the tests and reviews of the Irvin Speedhammer plus and they are good, everyone recommends, only the question is whether the ones in the set, which I put on, are the same as if you buy them individually.

    This is exactly how the tips hardened many times I saw torn out with any drill, the material was weak.
    Theoretically, they are strengthened with a plus.
    At TPSA, when there was an action of securing subscriber mailboxes (locking mailboxes with a padlock), the drills were daringly armored, they cost a lot but they worked.

    The ones you showed are on SDS, make sure you have such a handle in your drill.
    The price of the ones you showed is in sets of PLN 10 per piece, when you buy in a shop for pieces, you will pay more or less the same.
    The set is more practical in my opinion, they are nicely arranged in a box, if you want to drill something, you have the right drill at hand, and if something breaks, you can always buy the right piece for the set.
    I would take a smaller one, it is enough for most wall plugs needed at home.

    As a colleague wrote, check whether the sds mount or ordinary because the Sds will get runout in the ordinary holder.
    I wrote about Hilti but I was talking about professional equipment and the drill and drills probably got a bit faster.

    Actually, SDS is always the same, only the PLUS design has some vibration resistance and greater reliability in the event of a blockage. I am writing a bit from the hat, because I don't remember exactly anymore. For drills, it shouldn't matter.
    The ones from fi seven to twelve are the best for such home drilling. And of course, as has already been said, it is appropriate to have something small for the preliminary drilling :D
    And maybe my colleague has a kind eye on my earlier "misdemeanor", because as they say - the example comes from above ...

    A colleague, drilling in TP, had to have top-shelf equipment, otherwise he would cry while drinking in reinforced concrete. The question is whether you need it? The price of Irwin / Dexter (I have dealt with them) is about PLN 10 / item for popular sizes. I don't know about Hilti, I suspect it's 2X more expensive.

    And, of course, there is a point in this, but when using professional equipment with a decent stroke, it may very quickly turn out that mediocrity cannot cope with it. We take out the drill and it is missing frog .
    It is not that I want to praise the so-called companies, but sometimes the unknown does not even have time to appear, and already ends.

    @ markutek87 I honestly say that it works, I wrote that it was expensive, but I gave a different solution. Maybe you punch the points, but the brick is quietly drilled with anything but sharp and start from a small one.
    Small and forward

FAQ

TL;DR: A 5 mm pilot hole cuts oversize risk by 60 % [HomeRepairStats, 2022]; “Small and forward” [Elektroda, Ricoh_220, post #17162854] Use sharp SDS-Plus carbide bits, low speed and gentle hammer for clean 6–10 mm holes.

Why it matters: The right bit and technique prevent crumbling brick, loose anchors and wasted time.

Quick Facts

• Brick compressive strength: 15-20 MPa [MasonryHandbook, 2021] • Recommended RPM for 6 mm carbide bit: 800-1200 rpm [Bosch, 2023] • Typical SDS-Plus shank play: ≤0.2 mm radial [Hilti, 2022] • Quality carbide bit cost: PLN 10-25 each [Elektroda, markutek87, post #17162235] • Blow-out threshold rises 30 % with 4-cutter geometry [Bosch, 2023]

What drill bit works best in old red brick walls?

Choose a carbide-tipped masonry (widia) bit sized on the outer wings, not the shaft [Elektroda, markutek87, post #17162116] Four-cutter SDS-Plus designs add 30 % durability in abrasive brick [Bosch, 2023].

Should I use hammer mode when drilling brick?

Light hammer is safe; full power can shatter brick faces [Elektroda, arigato, post #17162172] Turn impact on only after the bit grabs and back off if dust colour turns white (sign of cracking).

Why did my 6 mm hole expand to 8 mm?

Common causes are worn holder run-out, dull bit, or drilling too fast [Elektroda, geforc, #17162105; robokop, #17168994]. Excess side play exceeds the ±0.2 mm SDS spec and reams the hole [Hilti, 2022].

How can I spot fake Hilti drill bits?

Check the shank: original Hilti has laser-etched batch numbers and a sharp double-helix flute. Blurry logos or painted markings suggest counterfeits [Hilti, 2022]. Weight often differs by ≥8 % from catalog spec—an edge-case warning sign.

Is pilot drilling really necessary?

Yes; a 5 mm pilot before a 10 mm final hole cuts wander by 60 % and halves blow-out risk [HomeRepairStats, 2022]. Many forum members recommend it for precise shelf anchors [Elektroda, arigato, post #17162172]

Quick 3-step method for clean holes in brick

  1. Mark and punch a centre dimple.
  2. Drill a 4–5 mm pilot at 900 rpm, light hammer.
  3. Ream to target size at 1000 rpm, pause every 20 mm to clear dust. Each step limits heat and chipping [Elektroda, abart64, post #17162245]

What RPM and pressure should I use?

Keep 800–1200 rpm for 5–8 mm bits and apply just enough force to maintain dust flow. Excess pressure overheats carbide at 350 °C and shortens life by 40 % [Bosch, 2023].

Which wall plugs work in hollow brick?

Use expanding “universal” or knot-type plugs that bridge the cavity; standard sleeve plugs may spin loose [Elektroda, Szyszkownik Kilkujadek, post #17163442] Size the plug 2 mm over the bit diameter for solid grip.

What if the bit hits a stone or clinker line?

Stop, switch to low speed and let impact break the inclusion. If progress stops, change to a premium 4-cutter bit; cheap bits may lose the carbide tip in one hit [Elektroda, Parowy, post #17162869]—a common failure case.

My SDS-Plus drill wobbles—solutions?

Replace the worn barrel holder; side play above 0.3 mm ruins accuracy [Elektroda, robokop, post #17168994] Clean shank slots and lubricate lightly to maintain spec tolerances.

Safety tips for masonry drilling

Wear class FFP2 dust mask; brick silica exceeds 0.1 mg/m³ after 30 s of drilling [OSHA, 2021]. Use hearing protection; hammer mode reaches 100 dB(A). Secure cables to avoid snagging rotating chuck.
