Automatic Gem Drill

For Medium to Soft Gemstone Material

Electronic feed raises and lowers drill chuck automatically 1/4". The light pressure of the feed prevents damage to diamond coated drill bits, but does result in a much longer drilling time. 

Abrasive drilling: When using drill tubes and 180 boron carbide grit, the Automatic Gem Drill is very economical. The best advantage is that it is automatic and does not have to be manually controlled. 

Plastic putty holds the work piece. The putty can also serve as a dam to hold grit around the tube. Unit comes with boron grit, 1/4" Jacobs chuck, two 1 1/2 and 2mm diamond drill bits, plastic putty, instructions and guarantee. Size 6"L x 4"W x 13"H.
