The use of cutting lubricants will reduce drilling heat and increase drill bit life. Tapping Select the proper tap and drill combination. Refer to the “Maximum Recommended Capacity” chart. On two-speed drill motors, use the low speed shift setting. Drill as described above. If possible, before moving the base to another This eliminates the need to the hole. Always use a quality tapping or oil for smooth cutting to the tap or workpiece. recommended 11 1. Insert the tap into the chuck. TIGHTEN THE CHUCK SO THAT THE CHUCK JAWS GRIP THE ROUND PORTION OF THE SHANK AND NOT THE FLATS OF THE TAP. 2. For tapping existing holes, align the tap so it is centered with the hole and reenergize the base. 3. Lubricate the tap and hole and lower the tap onto the work surface. Turn the drill speed control to the slowest setting and push the “Drill Fwd” button (“Drill Rev” for the left hand threads) to start the drill motor. Adjust the speed control knob so the tap turns slowly and smoothly into the hole. 4. When using smaller taps, reverse the motor as soon as the tap breaks through the hole. With large taps, reverse the motor as soon as the first full thread is exposed, the motor does not have to be stopped before changing directions. 5. Reverse the motor to slowly withdraw the tap from the hole. Maintain light pressure on the handle to compensate for the weight of the drill motor on the tap. As soon as the tap comes out of the hole, raise the motor and tap clear of the workpiece. NOTE: Only the low speed shift setting on the 2-speed drill is recommended for tapping. Using Twist Drills When preparing to drill, align the bit with the area to be drilled. When proper alignment is established, energize the magnet and start the drill motor. A pilot hole is recommended for drilling holes larger than 1/2" in diameter. When drilling, apply only enough force to produce a curled chip. Applying too little force will result in small broken chips and increased drilling time. Applying too much force will cause overheating of the bit resulting in short bit life. Overheating of the bit can be noticed when drill bit and chips turn brown or blue. Excessive force can cause the to slow down to a point where drilling will increase. The use of cutting lubricants will reduce drilling heat and increase bit life. Using MILWAUKEE STEEL HAWG™ CUTTERS MILWAUKEE STEEL HAWG™ CUTTERS cut an annular ring around the edge of the hole leaving the center “slug” intact. This greatly reduces the time, power and drilling force required. The carbide teeth also leave a finished hole that does not require reaming. These cutters are designed for use with an electromagnetic or industrial drill press. • Do not use these cutters in hand held tools. • Center pin is spring loaded. Provide protection from ejected slug for people and property below drilling area. • Do not remove cutter from arbor unless slug is removed. Slug may be ejected unexpectedly. • Keep pump bottle and hose away from moving parts. • Use pl...
