How Do Sds Drills Work

The hammer action on an SDS+ drill is driven by a piston firing the drill bit forward and pulling it back. The slots on the SDS+ drill bits allow an amount of back and forth motion and this, along with the smooth ball bearings, increases the strength of the hammer action of the drill.

What is the difference between a SDS drill and a hammer drill?

SDS Rotary Hammers are similar to Hammer Drills in that they also pound the drill bit in and out while it’s spinning. They use a piston mechanism instead of a special clutch enabling them to deliver a much more powerful hammer blow than traditional Hammer Drills – they are able to drill larger holes much faster.
