Applications

Selecting Hammer, Drill or Drive Action

MILWAUKEE Hammer-Drills have three operating modes: drilling with hammering action, drilling only, and driving screws. MILWAUKEE Driver Drills have two operating modes: drilling only and driving screws. To set the operating mode, rotate the application selector collar and torque selector collar to the desired symbols.

1.To use the hammer-drilling mode (Cat. No. 2611-20 only), rotate the application selector collar until the

hammer symbol appears in line with the arrow. Apply pressure to the bit to engage the hammering mechanism.

NOTE: The number selected on the torque collar has no effect on operation of the drill in hammer mode.

3.To use the driving screws mode rotate the application selector collar until the drive symbol appears in line with the arrow. Then rotate the torque selector collar until the desired clutch setting appears in line with the arrow.

To Drive Screws

The adjustable clutch, when properly adjusted, will slip at a preset torque to prevent driving the screw too deep into different materials and to prevent damage to the screw or tool.

The torque speciﬁcations shown here are approximate values.

Torque selector	Torque

1 - 5	0 - 16 in. lbs.

For reverse (counterclockwise) rotation, push in the control switch from the left side of the tool. Check direction of rotation before use.

To lock the trigger, push the control switch to the center position. The trigger will not work while the control switch is in the center locked position. Always lock the trigger or remove the battery pack before performing maintenance, changing accessories, storing the tool and any time the tool is not in use.

Starting, Stopping and Controlling Speed

1.To start the tool, grasp the handle ﬁrmly and pull the trigger.

NOTE: An LED is turned on when the trigger is pulled.

2.To vary the speed, increase or decrease the pressure on the trigger. The further the trigger is pulled, the greater the speed.

3.To stop the tool, release the trigger. Make sure the bit comes to a complete stop before laying the tool down.

Drilling

Place the bit on the work surface and apply firm pressure before starting. Too much pressure will slow the bit and reduce drilling efﬁciency. Too little pressure will cause the bit to slide over the work area and dull the point of the bit.

If the tool begins to stall, reduce pressure slightly to allow the bit to regain speed. If the bit binds, reverse the motor to free the bit from the workpiece.

NOTE: When using carbide bits, do not use water to settle dust. Do not attempt

17 - 27 in. lbs.

to drill through steel reinforcing rods. This will damage the carbide bits.

2.To use the drilling only mode, rotate the application selector collar until the

drill symbol appears in line with the arrow.

NOTE: The number selected on the torque collar has no effect on operation of the drill in drilling mode.

NOTE: Because the above settings are only a guide, use a piece of scrap material to test the different clutch positions before driving screws into the workpiece.

Using Control Switch

The control switch may be set to three

positions: forward, reverse and lock. Due to a lockout mechanism, the control switch can only be adjusted when the ON/OFF switch

is not pressed. Always allow the motor to

come to a complete stop before using the control switch.

For forward (clockwise) rotation, push in the control switch from the right side of

the tool. Check the direction of rotation before use.

WARNING To reduce the risk of electric shock, check work area for hidden pipes and wires before drilling or driving screws.

Drilling in Wood, Composition Materials and Plastic

When drilling in wood, composition materials

and plastic, select the drill-only operating mode. Start the drill slowly, gradually increasing speed as you drill. When drilling into wood, use wood augers or twist drill bits. Always use sharp bits. When using twist drill bits, pull the bit out of the hole frequently to clear chips from the bit ﬂutes. To reduce the chance of splintering, back work with a piece of scrap wood. Select low speeds for plastics with a low melting point.

Drilling in Metal

When drilling in metal, select the drill- only operating mode. Use high speed steel twist drills or hole saws. Use a center punch to start the hole. Lubricate drill bits with cutting oil when drilling in iron or steel. Use a coolant when drilling in nonferrous metals such as copper, brass or aluminum. Back the material to prevent binding and distortion on breakthrough.

Drilling in Masonry

When drilling in masonry, select the hammer-drill operating mode. Use high speed carbide-tipped bits. Drilling soft masonry materials such as cinder block requires little pressure. Hard materials like concrete require more pressure. A smooth, even ﬂow of dust indicates the proper drilling rate. Do not let the bit spin in the hole without cutting. Do not use water to settle dust or to cool bit. Both actions will damage the carbide.

Driving Screws and Nut Running

Drill a pilot hole when driving screws into thick or hard materials. Select the driving screws mode. Set the torque selector collar to the proper position and set the speed to low. Use the proper style and size screwdriver bit for the type of screw you are using. With the screwdriver bit in the screw, place the tip of the screw on the workpiece and apply ﬁrm pressure before pulling the trigger. Screws can be removed by reversing the motor.
