What sizes do masonry bits come in?

Masonry drill bits come in a variety of sizes to suit a broad range of needs. The smallest masonry bits are around 3/16 inch in diameter, with larger bits topping out at the ½-inch size. Hole saw bits have sizes that go up to 4 inches or more.

What drill bit is for masonry?

Drill bits that can drill through concrete are called masonry bits. They are also good for drilling through brick and stone. Drill bits with a tungsten carbide tip are the strongest; when it comes to solid concrete, the sharper the better. Masonry bits cut holes through concrete in two steps.

What’s the difference between SDS Plus and SDS Max?

SDS Plus have a 10mm shank, while the SDS Max has an 18mm. This means that SDS Max bits have an increased capability for tougher masonry work, withstanding more torque and force. The SDS Plus range is shorter in length and is tailored to lighter duty work and smaller diameter holes.

Why do my masonry drill bits keep breaking?

There are mostly two reasons why a drill breaks. Deflected breakage is caused by the radial force, the drill bit is broken at the end of flute. Twisted breakage is caused by the large torque, the drill bit is normally broken at the middle of the flute.

How do I identify a masonry bit?

Masonry bits look like larger twist drills with a slightly tighter corkscrew shape. You can identify them thanks to their wide arrow-shaped heads. They’re commonly used in hammer drills to grind masonry down as they cut through it. You can use them on brickwork, stone, breeze blocks, and other hard stone surfaces.

Why is my hammer drill not drilling through concrete?

Assuming the drill you have is working properly, you may have dull or worn bits. A masonry bit does not last long, especially in concrete or brick. Cheap bits are no bargain. Start with a new bit, when the speed of boring slows to about half or less, time for a new bit.

Why can’t I drill into brick?

However, if you have old, fragile brick and you’re mounting a heavy object that requires deep holes and expansion-style anchors, drilling into the brick may not be the best choice. Deep holes weaken the brick and expansion anchors can create enough circular stress to crack the brick.
