Can I Use an SDS Drill Bit in Hammer Drill?

SDS drill bits and hammer drill bits are different according to their chuck, usage, and mechanism. Using an SDS drill bit in a hammer drill is a real solution for drilling heavy-duty materials. Normally SDS drills are used for tough material drilling. But let’s see, using the SDS drill bit will help do the same job when it is used in a hammer drill.

SDS drill bits cannot be used in hammer drills because both tools are with different chucks, drill bits cross-sections, and mechanisms. When it mounts, jaws and rails do not tight well. Therefore SDS drill bit can’t be used in hammer drills due to the inclination of the drill bit.

Hammer drill and SDS drill are different as well as SDS plus; SDS max is also different by its mechanism, usage, and external tools. So will it be worth using the SDS drill bit in the hammer drill? So let’s keep read on all in detail step by step.

Difference Between SDS Drill and Hammer Drill Mechanism

As you are well aware regular drill is with the spinning mechanism. It is made for the drilling of soft materials such as plastic and wood. But you can drill concrete using that also. It will take too much time than you expect. So as a solution to this, a hammer drill is used.

Hammer drill is with hammering mechanism as it describes by its name. The Hammer drill has a hammering mechanism that is along the drill bit. That is very useful for drilling hard materials. There are gear teeth. When those are moving, they will slip and drop to the bottom position. This will create the hammering actions for the tool.

SDS drill also has a hammering mechanism. But it is different from the regular hammering mechanism. There is a piston-powered by a motor, and it connects to another piston inside. As a simple explanation using these pistons, the SDS hammering mechanism is produced.

Considering the hammer drill mechanism and SDS drill mechanism, there are huge differences. The reason is piston hammering mechanism is different from the gear teeth-based hammering mechanism. The piston hammering mechanism provides more power than the regular hammer drill.

Why There are Two Types of Chucks in SDS Drill and Hammer Drill ?

Chuck difference of Hammer drill and SDS drill

According to the hammering mechanism, the chuck has been designed. Chuck is the place where the tool is mounted. The regular hammer drill is keyless and with jaws. Those jaws can be loosened and then mount to the drill bit and tighten. So this is a simple task.

The hammer drill chuck is moving forward and backward when the hammer action happens. But consider the SDS hammer drills. There is no movement of the chuck.

Chuck is independent by moving forward and backward in SDS drills. The drill bit will move instead of chuck moving in the SDS hammer drill. SDS chuck is easy to use than a hammer drill chuck. There is no tighten. Just pull the back from the front and mount the tool and then move forward.

As well as there are no jaws. There is a ball a bearing. Due to the drill bit movement, it will not provide back force or any extra force to the user.

Consider the SDS and SDS max. There are different types of chuck because those are used for different types of tasks.

Difference Between SDS Drill Bits and Hammer Drill Bits

According to the above explanation, you can see there is a different mechanism in hammer drill and SDS drill, and also you can see there is a difference in the chuck and drill bits. Drill bits are made with different materials. Those drill bits are used for different purposes also. Due to this reason, hammer drill and SDS drill use different drill bits.

Regular drill bits are circular cross-section drill bits. But consider the SDS drill. This is slightly different. The reason is the hammering mechanism.

The regular hammer drill is not power than SDS hammer drills. So hammer drill bits are also not strong than SDS drill bits as well as with different cross-sections also.

Usage of SDS Drill and Hammer Drill

When you read on top, you can observe differences in the mechanism, chucks, and drill bits. So It is not difficult to imagine you to think those are used for different purposes. Of course, these are used for different purposes.

Let’s see the usages.

Hammer Drills– Hammer drills are used for drilling hard materials such as concrete, stones, brick, and much hard material. Using drill bits, it can depend.

SDS Hammer Drill – SDS is used for extra heavy works such as drilling concrete with rebars, chiseling, and many more.

Hammer drill is less power than SDS. So hammer drill is not able to use for the SDS purpose. But SDS can be used for regular hammer drill purposes.

Can I Use SDS Drill Bits On Hammer Drill?

SDS drill bit cross-section and hammer drill cross-section are different. Although the SDS drill bit can fit a regular hammer drill with its jaws, it can’t place direct. It will be inclined when it fits with jaws due to rails in the drill bits. Due to this reason, the SDS drill bit is not able to use in a regular hammer drill.

Because hammer drills are not much power for operating the SDS drill bits task. So it is useless.

Can I Use Hammer Drill Bits on SDS Drill?

Hammer drill bit can be used for SDS drill bit with using the SDS Drill bit chuck adaptor. SDS drills are more powerful than hammer drills. SDS drill can be used for any hammering task which used for the hammer drill. It will cost 15-20$.


After you have gain all detail you may understand that SDS drill bits are not able to use in hammer drills. Because jaws fit with rails as an inclination way. So it is not able to fix.

Hi, I am Tom Mackency. It has been 10 years that I have been working as a professional woodworker since 2013. I am really enjoying my carrier by creating many kinds of projects in my workshop. But mostly I like for home improvement projects. Home improvement and DIY projects are the most interesting things for me. More than that, the coolest things are power tools. Those are very precious and efficient than a decade ago. So I try to introduce so many things about power tools, woodworking, DIY projects, home improvement and many more interesting topics here.
