Automatic Gem Drill

       

MODEL # 600

The Automatic Gem Drill uses an electronic feed which mechanically raises and lowers the drill chuck 1/4". The light pressure of the feed prevents damage to diamond coated drill bits, but results in a much longer drilling time. Drill Tubes and 180 Boron Carbide Grit are a low cost alternative to diamond drill bits for this unit. Plastic Putty holds the work piece. The putty can also serve as a dam to hold grit around a drill tube. This unit comes complete with 1/4" Jacobs chuck, two (2) 1-1/2mm and two (2) 2mm diamond drill bits, plastic putty, instructions, and product guarantee.

OPERATING INSTRUCTIONS FOR MODEL # 600 AUTOMATIC GEM DRILL

 

INTRODUCTION

The model #600 drill is designed to drill medium to soft gemstone material. The drilling action is automatic and does not have to be manually controlled. The electronic field of the motor raises and lowers the chuck automatically 1/4 inch. The light downward pressure of the feed prevents damage to diamond coated drill bits, but it does result in longer drilling time.

DESCRIPTION

1/50 HP, 115V, 60 Hz motor turns the drill bit at 3040 rpm. Unit comes with 1/4" Jacob chuck, 1-1/2 and 2 mm drill tubes, cleaner, plastic putty, grit ring (ferrule), and guarantee. Size: 6"L X 4"W X 13"H. Shipping weight approximately 10 lbs.

INSTALLATION

Safety: Before plugging your drill into your electric supply, read the Covington Safety Demand Sheet. Your drill can be used portable. However, it is recommended that it be secured to a work bench during drilling.

ADJUST DRILL TABLE

The electronic field of the motor raises and lowers the chuck automatically 1/4". Before setting the height table, run and stop the drill so that the chuck is in the retracted (high) position. Set the table on the vertical upright shaft with ample space above the table for the gemstone. It will later be necessary to make a final adjustment in the table height so that the stone to be drilled is just under the drill bit tip. When starting again, the bit will automatically drill to a depth of 1/4". If a hole deeper than 1/4" is desired, the above procedure is repeated and the table raised.

USE OF DIAMOND COATED DRILL BITS

Select the bit size you want and insert one half its shank length into the chuck and tighten securely. The stone and drill bit must be kept cool. The best way to do this is to immerse the bit tip in water. Small Stones: Secure the stone to the drilling table with molding clay under and around the sides of the stone. If not in a pan, form a dam around the drilling area and fill with water. A drilling jig is recommended for drilling beads. Again, the tip of the bit should be covered with water. Diamond drill bits tend to chip the underside of the stone as they come through. This can be prevented by cementing the stone to a piece of glass if the bottom is flat.

USE OF DRILL TUBES

First run the wire cleaner through the proper size drill tube to see that it is clean. Then install the tube with about 5/8" extending out of the chuck. Tighten chuck so that the tube won=t be hammered back (upwards) while drilling.

Next, place the little grit ring (ferrule) over the center of where you want the hole in the stone. Press the molding clay around the ring so that it will stay in place and not leak water. Press two small pieces of molding clay on the back side of the stone, one on each side of where the drill tube will come through (to elevate the stone when in place on the drill table). Align the ring with the drill tube and press stone in place on the table.

USE OF DRILL TUBES CONTINUED:

Fill the ring reservoir with water and then add #602 boron carbide grit. An eyedropper and flat toothpick are useful when adding water and grit. Don=t use too much grit or it will plug the drill tube. Raise the table so that the stone to be drilled is just under the drill tube. The stone is now in position to be drilled automatically.

DRILLING

Using tubes and grit, the drill will penetrate 1/32" to 1/8" in 15 minutes, depending on the hardness of the material. Larger sized drill tubes or diamond core drills cut faster.

When drilling action slows, it usually indicates that the tube is plugged up with core material or grit. In this event, stop the drill, drop the table down and then remove and examine the drill tube. Clean the tube with the cleaning pin and reinstall in the chuck. The drill will not operate satisfactorily if the tube is plugged up.

MAINTENANCE

Keep the upright shaft well oiled. Oil the motor bearings located on each end of the motor with 1 drop of 3-in-1 oil every six months. Caution: Do not over oil bearings.

Lubricate the gears with grease each month. A multi-purpose white grease is a good type to use.

WARNING: The motor has a normal working temperature that is too hot to touch.

If the motor should stop, just give the drill chuck a turn to the right to restart it.

Caution: Keep grit away from the chuck, gears, and bearings.

OPERATING INSTRUCTIONS FOR MODEL #605 DRILL

 

INTRODUCTION

The model #605 drill is a multi-speed unit that can be used for drilling, carving and buffing with appropriate accessories. It is designed for clean, fast and accurate drilling on medium to soft gemstone material.

DESCRIPTION

Unit has a 1/15 HP, 115V, 60Hz, 5,000 RPM motor with foot operated speed control.

Drill lever gives user a 3/4" stroke.

Bracket and motor can be quickly adjusted for height or removed and mounted horizontally to convert unit into a buffer and carver.

INSTALLATION

Safety: Before plugging your drill unit into your electrical supply, read the Covington Safety Demand Sheet.

It is recommended that it be secured to a work bench for drilling and it MUST be secured before using as a carver or a polisher.

PREPARATION

Select the drill bit size you want and insert one half of its shank length into the chuck and tighten securely.

The stone and drill bit must be kept cool. The best way to do this is to immerse the stone in a pan of water.

The stone can be held by hand, but for absolute steadiness, some type of holding device should secure both the gem and pan.

Small Stones: Secure the stone to the drilling table with molding clay under and around the sides of the stone. If not in a pan, form a dam around the drilling area and fill with water. A drilling jig is recommended for drilling beads.

Again, the tip of the bit should be covered with water.

A clamp can be used to hold the gem and pan. Diamond drill bits tend to chip the underside of the stone as they come through. This can be prevented by cementing the stone to a piece of glass if the bottom is flat.

DRILLING

Turn on the drill and place your foot on the rheostat. To start, run the drill at low speed. Gently lower the drill bit until it contacts the gem. Apply very little pressure until the bit has cut into the surface of the stone. This is especially important if you are drilling a curved surface. After the hole is started, you can increase the pressure.

The speed can also be increased with the rheostat. At short intervals, raise the bit slightly so that fresh water can flow into the cut. Until you learn how to use a diamond drill, be very careful with pressure. Reduce the pressure considerably when the hole is almost through.

 

 

Gem Drill Accessories

The Nugget and Bead Vise is designed to hold beads up to 3/4" in diameter for drilling. Always drill with the vise submerged in water to keep the drill bit cool and to sustain a longer drill bit life. This unit comes with a 3" diameter x 5/8" deep aluminum tank.

The Putty Vise is designed to hold small pieces of gemstone or glass for drilling. Always drill with the work piece submerged in water to keep the drill bit cool and to sustain a longer drill bit life. This unit comes with a 3" diameter x 5/8" deep aluminum tank, a 1" square block of plastic putty and a 1/4" brass ferrule. The plastic putty holds the work piece and the brass ferrule can act as a dam to hold grit or water when drilling.
