How to Use an SDS Max Rotary Hammer Drill

SDS Max rotary hammers, you may need to push back the chuck towards the rear of the tool, and hold it while inserting the drill bit. Give the drill bit a twist, and a spring-loaded retainer will lock the bit in place.

Some rotary hammers also come with rotatable chucks that lock at the current angle when the tool is in use. If you are using a chisel on your rotary hammer, this lets you set the chisel at the proper angle before you start chiseling.

Point the tip of the drill bit to the target area, and take a second to find your footing. For drilling holes into concrete, it often helps to set the tool to “drill only” mode to make a pilot hole. Then once the bit is nicely settled into a pilot hole, you can switch to “hammer and drill” to drill the rest of the way.
