The DEWALT DW5470 SDS-Plus 2-cutter drill bit set delivers the durability and speed you need for masonry drilling. These bits feature a strong, tapered core to resist flute breakage in deep holes, plus a two-stage flute design that clears debris quickly. With rock carbide tips and two sharp cutting edges, they produce clean, round holes ready for anchors and Tapcon screws. This five-piece set is a practical addition to any mason's bag, and the No Break Guarantee means DEWALT stands behind the bit's performance.
Each bit uses two cutter edges that remove material aggressively while maintaining a true hole geometry. The tapered core adds strength at the flute, so the bit is less likely to break when you're drilling deep into concrete. The variable helix flute pattern keeps dust moving out of the hole, preventing clogging and improving drilling speed.
Tapcon screws require the correct pilot hole size for proper anchoring. The DW5470 set includes the 5/32-inch bit for 3/16-inch Tapcon anchors and the 3/16-inch bit for 1/4-inch Tapcon anchors, so you can tackle a range of fastening jobs without searching for a separate bit. The sharp carbide edges cut through concrete and block cleanly, giving you a precise hole for a secure hold.
The rock carbide tip is engineered for long life in abrasive materials, and the hardened steel body resists bending and breakage. A wear mark indicator lets you know when the bit is no longer cutting at its best. With DEWALT's No Break Guarantee, you're covered if a bit fails while the wear mark is visible.
This set is ideal for plumbing, electrical, and general construction pros who drill into concrete, brick, or block on a regular basis. It's also a great choice for homeowners hanging shelves, installing Tapcon anchors, or securing fixtures to masonry.

SDS-Plus bits are the standard for rotary hammer drills. The SDS-Plus shank locks securely in the chuck and allows more efficient impact energy transfer.
For 3/16-inch Tapcon anchors, use a 5/32-inch SDS bit. For 1/4-inch Tapcon anchors, use a 3/16-inch bit. Drill the hole to the specified depth, clean out the dust, and drive the screw. The two-cutter design of the DW5470 helps produce accurate holes for a secure anchor.
Start at a low speed with moderate pressure, then increase speed once the bit is seated. Let the bit do the work; too much pressure can overheat the carbide. Use the two-stage flute to clear debris, and withdraw the bit periodically in deep holes.
Keep bits sharp by avoiding steel rebar when possible. If you hit rebar, slow down to reduce heat. Replace the bit when the wear mark disappears to maintain drilling performance.
Drilling holes in concrete, brick, block, and masonry using SDS-Plus rotary hammers.
The set includes 5/32-inch and 3/16-inch bits, which are the correct pilot hole sizes for 3/16-inch and 1/4-inch Tapcon anchors.
No, they require an SDS-Plus chuck or an SDS-Plus adapter for a regular hammer drill.
DEWALT will replace any bit that breaks while the wear mark is visible, excluding certain models listed in the warranty terms.
The wear mark indicator is located near the shank. Once it's gone, the bit has reached the end of its effective life.
Drill into concrete easy.
I used these to drill pilot holes for Tapcon screws. They went in quickly. The bits are sturdy. I did 50 holes and they're still sharp.
It goes through concrete fine, but if you hit rebar, it stops. I guess that's expected. The bits are decent.
Very durable.
I used them to hang shelves on brick. They didn't dull. The set has all sizes I need. I'm happy.
I've used many brands. These are the best. They cut fast. They don't walk. The 2-cutter design is efficient. I've used them on block and brick.
The bits are great. The case is cheap and doesn't stay closed. But I'll keep the bits.
Cuts through concrete like butter.
I've used these for my deck project. They go through concrete block easily. The pilot hole is clean. I recommend them.
These bits are unbelievable.
I've drilled dozens of holes in concrete and the bits are still good. They fit my SDS-Plus rotary hammer perfectly. The two cutting edges make the hole straight. I'm a fan.
