Setting up the XT3000 The XT-3000 comes equipped with grinding wheels, a sharpening fixture and 2 chucks, 1; 3mm – 12mm & 1; 12mm – 21mm. 1. Remove from shipping box and all packaging material before powering up the machine. NOTE: Due to the weight of the XT-3000, it is suggested that the lip of the casting, located above the motor ,can be used as a handle for lifting. 2. Located at the back and on the right side of the XT3000 is the power receptacle.

Drill Alignment The alignment port is located on the left side of the XT-3000. or counterclockwise to increase material removal. Setting Alignment Tube for Desired Heel Relief The first stage to sharpening a drill starts with the alignment process. In the alignment process, you will go through a few necessary steps prior to sharpening. Setting the material removal amount, adjusting the alignment tube to produce desired relief amount.
PAGE 12
Drill Alignment To decrease heel relief, rotate clockwise. 135° 4. Rotate the chuck knob clockwise, which closes the chuck jaws onto the drill. Then slightly loosen the chuck jaws by rotating the chuck knob counterclockwise, about ½ turn. To determine how tightly the drill should be held during the alignment process, the drill should slide freely and drop out when the chuck is held in a vertical position. 5. Insert the chuck and drill into the alignment tube.
PAGE 13
Drill Alignment 6. 7. S-L-O-W-L-Y squeeze together the red slide handle until it touches casting. We emphasize slowly, because squeezing the handles too quickly pushes the drill too deeply into the chuck. NOTE: If this happens, the drill will not touch the wheel during the sharpening process. With the handles held together, look through the viewing port and see if drill is positioned correctly. · · CORRECT 8. The pawls should be seated in the helix of the drill.

Drill Sharpening The Sharpening fixture is located on the right side of the machine. 3. After sharpening fixture is in place, rotate the locking lever clockwise until snug. This will secure the fixture to the base. Adjusting the Point Angle You must loosen the sharpening fixture and slide the point angle indicator to the desired degree. Mounting the Sharpening fixture 1. 1. Rotate the locking lever so the flat edge is at the top, horizontal and in a straight line with the base casting.

Drill sharpening WARNING: Make sure the Split Port Cover and eye shield are in place before grinding. (International Machines Only) Power up machine 2. Insert the chuck with the thickest part of the cam touching the swing bearing. 3. Release sharpening tube very slowly. 4. With slight pressure towards the grinding wheel, rotate the chuck 360 degrees, several times in a clockwise direction.

Drill Point Splitting The Point Splitting Port is located in the center of the machine. point. NOTE: Do not force the chuck into the grinding wheel or damage to the drill or wheel may occur. Adjusting the Depth of Split Approximately 3-7° rake is created, producing a drill with a self-centering point. Its advantages are the ability to reduce thrust and eliminate walking at the drill point. This is a distinct advantage where drill bushings/fixtures are not used.

Drill Point Splitting POINT SPLIT ANGLE DIAGRAM 12 0° 13 0° drill more strength and durability. This added split angle creates a pointed profile at the very center of the drill, producing a selfcentering effect and reduces drill point walking at the start of a hole. 118° 135° 118° 135° 1. Loosen the point split nut by rotating the nut counterclockwise. 2. Rotate the point split angle adjuster clockwise to increase the split angle. 95 ° 10 5° Pointed 3.
