When you're drilling through steel, timber, masonry or metal, having the right DeWalt drill bit set makes all the difference. Whether you're a chippy boring through hardwood frames, a sparkie running conduit through brick, or a fitter drilling through plate steel, DeWalt has a drill bit built to handle it.
Tool Kit Depot stocks a full range of DeWalt drill bits across timber, metal and masonry applications. From compact drill bit kit options for your ute to comprehensive sets that cover the lot, you'll find bits engineered for accuracy, speed and durability on the tools.
For metal drilling, DeWalt cobalt drill bits deliver serious heat resistance and edge retention when you're working with stainless or hardened steel. The cobalt twist bits stay sharper longer and power through tough materials without dulling out halfway through the job.
If you're chasing holes in concrete or brick, the SDS drill bit range is built for hammering through masonry fast. Pair them with an SDS rotary hammer, and you're sorted for anchors, electrical rough-ins or plumbing penetrations.
For timber work, the wood drill bits include spade bits, auger bits and brad point designs that bore clean holes without tear-out, perfect for joinery, framing or cabinet installs.
These bits are built tough with carbide tips, split-point geometry and flute designs that clear waste fast. The twist drill bit range handles everyday metal and timber drilling with precision, while specialised sets give you the edge on tougher materials.

DeWalt drill bit set FAQ
What's the difference between cobalt and standard drill bits?
Cobalt bits contain added cobalt alloy, which increases heat resistance and hardness, making them ideal for drilling through stainless steel, cast iron and other tough metals. Standard HSS (high-speed steel) bits work fine for mild steel, aluminium and general metalwork, but they'll dull faster on harder materials. If you're regularly drilling metal that generates heat or resists standard bits, the cobalt set is worth the upgrade for longer tool life and faster penetration.
Can I use wood drill bits on metal?
No, it's not recommended. Wood bits like spade bits or auger bits aren't designed to handle the hardness or heat of metal and will dull immediately or break under load. Metal drilling requires twist bits with the right tip geometry and material hardness to cut cleanly without overheating. Stick to HSS or cobalt twist bits for metal, and save your timber bits for their intended job.
How do I choose the right drill bit for masonry?
For masonry, you need bits with carbide tips that can handle the abrasive nature of brick, concrete or stone. SDS bits are your go-to if you're using a rotary hammer; they lock into the chuck and deliver the percussive force needed to power through hard surfaces. Standard masonry bits work with hammer drills for lighter tasks like anchors in brick or render. The SDS drill bit set covers a solid range of diameters for everyday trade work on site.
Do DeWalt drill bits fit all drills?
Most standard bits use round shanks that fit any keyed or keyless chuck, including DeWalt drills and other brands. SDS bits are different; they require an SDS chuck found on rotary hammers, not standard drill/drivers. Check your drill type before buying, and make sure the shank matches your chuck. Hex shank bits fit impact drivers and some drills with hex chucks, giving you quick bit changes without a chuck key.
How long do DeWalt drill bits last?
Lifespan depends on what you're drilling, how hard you push and whether you're using cutting fluid on metal. Cobalt bits handle heat better and last longer on tough metals compared to standard HSS. Masonry bits wear down faster on hard aggregate concrete, but hold up well on softer brick. Keep bits sharp, avoid overheating by using the right speed and pressure, and they'll go the distance. Store them properly in a case to avoid damage between jobs.
