The DEWALT DW5455 SDS+ hammer bit is built for tough masonry drilling. With a rock carbide tip and a tapered core that resists flute breakage, this 3/4-inch by 10-inch by 12-inch bit handles deep holes in concrete, brick, and block. The two-stage flute design quickly clears debris, and the wear mark indicator lets you know when it's time for a replacement.
This 12-inch overall bit gives you a 10-inch working length, so you can drill deep anchor holes or pass through thick walls. The SDS+ shank offers quick and secure 2-slot lock-in for compatible rotary hammers, ensuring efficient power transfer and reduced slippage.
The two sharp carbide cutting edges shear through masonry while staying cool and resistant to wear. This is the bit you want for overhead drilling or tough reinforced concrete. While it's not designed to cut rebar, the carbide tip can handle occasional contact with rebar better than standard masonry bits.
The two-stage flute design with a variable helix pattern pulls dust and debris away from the cutting edge, reducing jamming and allowing the bit to cut at optimal speed. That translates to faster hole drilling with less effort.
Trusted by pros and backed by DEWALT's No-Break Guarantee—if the bit fails while the wear mark is still visible, it will be replaced. This bit is for use with SDS+ rotary hammers only.

Drilling into concrete is tough on bits. The DW5455 is built to handle that abuse with a stronger core and a flute design that clears material efficiently. Its No-Break Guarantee means you can work with confidence.
SDS+ bits (like this one) are ideal for rotary hammers up to 2 inches in diameter. For heavier demolition drilling above 2 inches, you'd need SDS-Max. For most anchor and through-hole work, SDS+ is the sweet spot.
Backed by DEWALT's commitment to quality, the DW5455 is a bit you'll reach for again and again.
The DW5455 is designed for masonry and concrete. Its carbide tip can occasionally strike rebar without breaking immediately, but it's not a rebar cutting tool. For drilling through reinforced concrete, you may need a rebar cutter or a bit with a SDS-Max shank and a specialty tip.
The wear mark is a groove on the bit. As long as the groove is visible, the bit is within its usable life. If the bit breaks while the wear mark is still visible, you're eligible for a replacement under the No-Break Guarantee.
Yes, the SDS+ shank fits all SDS+ rotary hammers, including DEWALT, Bosch, Makita, and others.
The DW5455 is a 2-cutter design, which provides a better balance of speed and durability. A 4-cutter tip is designed for larger diameters and faster drilling in softer material. For 3/4-inch holes, the 2-cutter is ideal.
The working length is 10 inches, so you can drill up to 10 inches deep if your hammer's depth gauge allows. The overall length is 12 inches, so it's safe for a 10-inch hole.
Goes through concrete fast.
Used it with my SDS+, drilled a bunch of holes. Still sharp.
I'm a DIYer and I needed to hang a TV on concrete. This bit made clean holes without jumping around. It didn't get stuck, which my old bit did. The rock carbide tip definitely helps. It's not cheap but worth it.
I've burned through cheap bits on this job, so I tried this one. It held up to rebar and hard concrete with no breakage. It's a bit pricey, but it lasts longer than the budget ones, so cost per hole is lower. The SDS+ connection is solid, no wobble. I'll be buying more.
Good bit, but the dust gets stuck in the grooves. Works well after cleaning.
I've been drilling concrete since before SDS existed. This bit is as good as any I've used. It stays cool and cuts fast, even in cured concrete. The length is enough for thick walls. I recommend it for anyone who wants a reliable bit.
Solid carbide tip.
Works great with my DeWalt hammer. No complaints.
I just started a concrete business and this bit is my go-to. It drills clean holes in block and poured concrete. The no-break guarantee gives me peace of mind. It's a little pricey compared to knockoffs, but it saves time. I already ordered a second one.
Does what it's supposed to. Drilled many holes with no chipping.
I'm a mechanical contractor and I use these for anchor holes in slab. This bit stays sharp longer than my previous brand. It handles rebar surprisingly well, though you're supposed to avoid it. The shank is snug in my rotary hammer, no play. Good product.
Fit my chuck perfectly. Fast cut.
Excellent bit!
