Using an E-drill vs drilling a Visu-Lok / Jo-Bolt. The removal of blind-bolt fasteners (Jo-Bolt, Composi-Lok, Visu-Lok, Radial-Lok etc.) using a traditional twist drill can take up to 8-10 minutes to remove manually. The E-drill can complete the task in much less time (watch the video)... These are typically the most difficult Fasteners to Remove and the most Damage Prone. Titanium variants of these fasteners used on composite airframe structures are especially challenging.
For those of you who don’t know Perfect Point, our latest generation E-drill Pro 150 Series provides forceless electro-discharge machining (EDM) cutting for repeatable accuracy and effectiveness on a scale that conventional twist drilling cannot. You can consistently remove the head or collar from hard-metal fasteners (titanium, steel, and nickel alloys) in less than 10 seconds with a minuscule damage rate (less than 1%), versus the more common five to seven minutes demanded by standard twist drills. What’s more, easy-to-use alignment tools ensure accurate cuts with no damage to the parent structure.
Using the E-drill, you could:
 Reduce labor cost and lost time
 Improve accuracy and cut damage rates from 20% to less than 1%
 Eliminate FOD due to drilling debris
 Protect mechanics from career-ending injuries
 Prevent unwanted exposure to noise-driven hearing loss
