"<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.&nbsp; It will drill through precious stones, semi-precious stones, ferrite, silicon, glass, and ceramics.&nbsp; This is completed by the solid-state transducer transforming A/C current into mechanical vibration of about 20 KHz per second.&nbsp; 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.&nbsp; It usually outperforms diamond drilling tools and the consumable items are more cost effective.&nbsp; 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.&nbsp; 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.&nbsp; 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.&nbsp; In addition you will receive 10 meters ( 25 tubes per meter) of the sizes&nbsp; of your choice.&nbsp; The tubes come in .5mm, .8mm, 1.0mm, 1.5mm, 2.0mm, 2.5mm, 3.0mm, 3.5mm, 4.0mm, and 5.0mm. &nbsp;Additional quantities of tube are available for purchase.&nbsp;&nbsp;</span></span></p> <p><span><span><span>The d
