Dewalt DC925 Drill Instructions

The Dewalt DC925 is a heavy duty 1/2-inch, cordless hammerdrill/drill/driver. Powered by an 18-volt DC motor that produces 500 watts of power, the DC925 has a patented three-speed transmission to allow matching the drill speed and torque to the application. Its self-tightening 1/2-inch chuck automatically tightens during the drilling process, insuring maximum bit grip. In hammerdrill mode, it can produce 34,000 blows-per-minute for tough masonry drilling. The DC925 weighs 2.5 pounds and operates off a rechargeable 18-volt battery pack.

Instructions

  1. Battery Pack

    • 1

      Make sure that the battery pack is fully charged.

    • 2

      Line up the notch inside the drill's handle with battery pack. Firmly slide the pack into the handle until the lock snaps in place.

    • 3

      Remove the battery pack by pressing the two release buttons on opposite sides of the battery pack and sliding the battery pack out of the drill handle.

    Self-Tightening Chuck

    • 4

      Clamp a drill bit or other tool in the self-tightening chuck by first locking the trigger in the "OFF" position.

    • 5

      Grasp the chuck sleeve with one hand while using the other hand to hold the tool. Rotate the sleeve counterclockwise to open the chuck far enough to accept the bit.

    • 6

      Insert the drill bit about 3/4-inch into the chuck. Rotate the chuck sleeve clockwise as far as it will turn. As the drill is operated, the chuck will self-tighten onto the bit.

    Three Speed Transmission

    • 7

      Select the torque and speed setting for your application by sliding the gear shift lever.

    • 8

      Select position "1", which is furthest to the left, for the highest torque.

    • 9

      Select position "2" in the middle for medium torque and speed.

    • 10

      Select the highest speed setting by turning to position "3" which is all the way to the right.

    Standard Drilling

    • 11

      Turn the collar to the symbol representing either drilling or hammerdrilling mode according to your application.

    • 12

      Use the gear shifter to select the desired speed/torque range.

    • 13

      Pull the trigger to begin drilling. Apply pressure in a straight line with the bit. Do not push so hard that you stall the motor or deflect the bit.

    • 14

      Hold the drill tightly to control twisting action caused by torque.

    Hammerdrill Operation

    • 15

      Turn the collar to the hammerdrill symbol.

    • 16

      Pull the trigger to begin drilling. Drill straight, keeping the body of the drill in line with the bit. Apply just enough force to keep the drill bit from bouncing.

    • 17

      Use carbide-tipped bits or masonry bits for drilling in masonry.

    Screwdriver Operation

    • 18

      Select the desired speed/torque range using the gear shift lever.

    • 19

      Clamp the screwdriver bit in the chuck in the same manner as you would with a standard drill bit.

    • 20

      Make a few test runs driving screws in scrap pieces to determine the proper torque and speed for the size of the screw and the material.
