10 These drills are supplied with a No. 3 Morse Taper Socket. To insert a bit or adapter into the socket: 1. Make sure the taper is clean and lightly oiled. Foreign material can cause misalignment. 2. Insert the taper into the socket and rotate the taper until the bit tang slides into the slot at the top of the socket. 3. Press the taper firmly into the socket, or use the feed handle to press the bit against a piece of wood. To remove a bit or adapter from the socket: 1. Unscrew the knurled collar and remove the entire Morse Taper Socket. 2. Strike the bit tang firmly with a soft metal mallet or strike the bit tang firmly on a wood or soft metal surface. 3. Replace the Morse Taper Socket by aligning the notches with tabs on the drill. 4. Replace the knurled collar and 10 APPLICATIONS Fig. 11 DANGER To reduce the risk of injury, always keep hands, rags, clothing, etc. awayfrom moving parts and chips. Do nottry to remove chips while the cutteris rotating. Chips are sharp and canpull objects into moving parts (SeeFig. 11). Drilling When preparing to drill, align the bit with the spot 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 drill to slow down to a point where drilling time will increase. 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 ...
