6 Comments on “how is a masonry drill bit look different to a metal or wood drill bit?

  1. The ones my dad has have a red mark on the tip. Otherwise I think they all look pretty much the same.

  2. The only difference is in the density of the metal, there is very little difference in appearance unless you mean various specialist wood bits.

  3. A masonry bit will have carbide steel fastened to the cutting edge of the bit. Whereas the metal or wood bit will not. Regards, Dale

  4. A masonry drill bit has a much wider tip with tabs on each side of the tip (unless it’s been heavily worn down), the spirals are generally wider too.

  5. === if you go shopping for a masonry bit you can ask the hardware clerk to point out the bit that is the size you want — use of wood or metal bits in concrete or brick only destroys those drill bits .. AND …… the use of a hammer drill for boring into concrete or brick will make the job much easier and the hammer drill motor is designed for that purpose … normal drill shaft gets warped when attempting to bore concrete/brick/mortar ………………..

  6. In the provided link, from left to right:
    HSS or high speed steel.
    Carbide tipped for masonry. This 1 is for a hammer drill as you can see the slot near the bottom that you’d remove the bit from the drill with.
    Brad point for wood and soft materials.
    Another masonry drill bit for most standard and some hammer drills. You can see the carbide tips that are silver soldered or brazed on to the steel shank.
    Next is a glass or ceramic bit, the 1 that is similar to an arrowhead at the tip.
    And the final 1 on the far right is a centering bit for machine work such as lathes or Bridgeport types of milling machines, but can be used in hand drills as well.
