Impact Drivers

How Do Impact Drivers “Melt Screws In”?

Until you try one, you simply won’t believe how effortlessly an Impact Driver drives screws. Unlike driver/drills that simply rotate the drill or driver bit, Impact Drivers apply a series of high-speed rotary hammer blows to the driver bit, just like the impact wrench the tire guy uses to install lug nuts. That rotary force minimizes the axial force (pushing) required to keep the driver bit in the recess, so screws seem to just “melt” right in!

Power Driver Comparison Test

Batteries were fully charged for four tools:

• Two Makita Impact Drivers:
• 12v #6980DWDE with a 2.6Ah battery
• 14.4v #6935DWDE with a 2.6Ah battery

• Two Driver/Drills:
• Makita 14.4v #6336DWDE
• DeWalt 12v DW953

Each tool drove our No-Co-Rode #8 x 3" deck screws continuously until unable to fully sink the screw in a pressure-treated pine test block.
