The spiral flutes behind the tip don’t actually cut at all, they are there to funnel waste out of the way. It is wider, and designed to chip away at the surface while it rotates. Many share the same base material, high-speed steel (HSS). General-purpose masonry bits for hammer drills have the same round shanks as found on standard drill bits for wood or metal. SDS hammer drills have a spring-loaded chuck, with ball bearings that lock into grooves on SDS drill bits. These are often keyless, but heavy-duty models have a keyed chuck, which allows for a tighter grip on the drill bit. The majority of hammer drills have a self-centering three-jaw chuck. Photo: Each has a different chuck and accepts different bits. RELATED: The Best Drill Bit Sharpeners for Tool Maintenance This is valuable when driving into softer materials like wood or drywall, preventing you from accidentally driving the screw below the surface or even, as can happen, right the way through. The clutch on a cordless drill/driver allows you to reduce the amount of torque applied to a screw so that when that limit is reached, the clutch slips and the chuck stops rotating. Impact drivers are the perfect tool for heavy-duty driving, but most aren’t intended for delicate, precision work. Small hammer drills can be used to drive screws (some consumer-grade models incorporate a clutch), but many are too large and powerful. However, this tool has a different trick up its sleeve: the addition of a clutch. Modern versions offer greater flexibility with variable speed.Ī cordless drill/driver has the simplest action, in that it is purely rotational without any additional force. Early impact drivers were very much brute force, all-or-nothing tools. Thus the focus of the force is to drive screws and other fasteners, or indeed undo them. It makes a similar sound to a hammer drill, but the energy goes in the same direction as the chuck rotation, not in a straight line along the drill bit. It is compressed every half turn then releases, delivering tremendous force. Inside the impact driver body is a heavy-duty spring. ![]() In some ways it does, though an impact driver provides increased rotational energy, better known as torque. Many hammer drills allow this, though some SDS models do not.ĭescribing a tool as an “ impact driver” might suggest it has a similar action to a hammer. To do that, the hammer action needs to be disengaged. However, while heavy-duty slotted drive system (SDS) models are capable of drilling through walls several feet thick, it is not an effective way to drill wood, plastic, or metal. It’s an action that’s particularly effective in drilling brick, cinder block, concrete, and similar materials. In effect, it combines chiseling and drilling in the same tool. While the drill rotates, a gear-driven cam introduces a linear striking motion along the path of the drill bit. The action of a hammer drill is right there in the name: it’s a hammer and a drill working in tandem.
