SDS (Special Direct System) drills resemble normal hammer drills but are more powerful and can used with drill bits larger than the maximum of 13mm of standard hammer drills.
SDS drills are ideal for heavy duty work and professional applications.
SDS drills have an improved hammer action with greater power - ideal for punching staples into your fence posts.

SDS drills have 3 modes.

• Drill: Normal drill action although with more torque.
• Drill & Hammer: Similar to a normal drill but with more power.
• Hammer Only: Allows an action similar to a chisel - This is the mode to use driving staples.
