"<p><span>This all-new model is fully self-tuning which means once you have properly attached the tool, you turn it on and adjust the power for the material you are machining.</span></p> <p><span>This ultrasonic drill is designed to drill .5mm-4.0mm holes, engrave (with a solid die) up to 8mm, and cut hard brittle materials by using ultrasonic energy.  It will drill through precious stones, semi-precious stones, ferrite, silicon, glass, and ceramics.  This is completed by the solid-state transducer transforming A/C current into mechanical vibration of about 20 KHz per second.  Feed the 220g graded silicon carbide abrasive onto the tool and work piece to drill or grind the your piece, forming a hole that is the same shape as the tool.</span></p> <p><span>Ultrasonic cutting is fast and clean.  It usually outperforms diamond drilling tools and the consumable items are more cost effective.  For example, a diamond-plated drill usually costs between $1.00 and $5.50 and will last from 1/2 hole to 2-3 holes.  The drill tube for the ultrasonic costs from $.08 to $.24 each and lasts for 10-20 holes in agate and 50-100 holes in glass.  A 1.0mm hole can be cut in an agate slab of 4.0mm thick in about 60 seconds. The same can be done to glass in about 15 seconds.</span></p> <p><span><span>This machine comes with 5 horns, a propane torch, flux, silver solder, tools, spare fuses, 5 lbs. of 220g graded silicon carbide, a pump and water manifold.  In addition you will receive 10 meters ( 25 tubes per meter) of the sizes  of your choice.  The tubes come in .5mm, .8mm, 1.0mm, 1.5mm, 2.0mm, 2.5mm, 3.0mm, 3.5mm, 4.0mm, and 5.0mm.  Additional quantities of tube are available for purchase.  </span></span></p> <p><span><span><span>The d
