Perfect Point EDM Knowledge Base

The standard S-Blaster hose is approximately 6 feet long, providing ample reach for most aerospace maintenance tasks. Unlike traditional blast systems that require stationary booths or fixed connections, S-Blaster’s hose connects to a lightweight, backpack-mountable unit—giving technicians full freedom of movement.

Perfect Point EDM products are proudly designed, manufactured, and assembled in the USA, with final assembly and testing completed at our Huntington Beach, California headquarters. Every tool meets aerospace-grade standards for precision and reliability.

S-Blaster uses reusable plastic blast media, along with locator cups, seals, and air/HEPA filters that are replaced periodically based on usage and coating type. Detailed specifications and recommended replacement intervals are provided in the S-Blaster user guide.

Yes. S-Blaster is designed for use on delicate surfaces, using MIL-SPEC plastic media, controlled pressure, and a tightly focused blast zone to safely remove coatings without damaging composite or carbon fiber structures.

S-Blaster is engineered to use fine, aviation-grade plastic blast media that complies with MIL-SPEC standards, ensuring safe and effective surface preparation on aircraft structures. Two main types of media are available depending on the material you’re working with:
• Type II: Designed for use on metal skins and surfaces, ideal for cleaning fastener heads and coatings without scarring the metal.
• Type V: Engineered for composite materials, including carbon fiber structures. This media type ensures coating removal without compromising structural integrity.
Both media types are compatible with S-Blaster’s controlled pressure and sealed recovery system, ensuring minimal waste and maximum safety.

Yes. While S-Blaster is commonly paired with E-Drill to prepare coated fasteners for EDM removal, it’s also widely used as a standalone tool for cleaning paint and coatings off screws and fasteners where drilling isn’t required. You can purchase S-Blaster separately or as part of an E-Drill system bundle.

Typically, the blast diameter ranges from 0.250″ to 0.600″, based on locator size and settings. This ensures clean coating removal without affecting the surrounding area.

S-Blaster was designed with technician mobility in mind. Unlike large blasting cabinets or bulky surface prep systems, S-Blaster is a lightweight unit that can be worn as a backpack. This backpack-mounted configuration gives users complete freedom to move around the aircraft or worksite without the need for carts, extension arms, or external blasting chambers.

Its compact form factor and ergonomic layout make it ideal for working in confined areas, on overhead surfaces, or across large aircraft sections without repositioning heavy equipment. Whether you’re depainting fasteners on a vertical stabilizer, prepping panel screws on the flight line, or touching up a composite surface in a tight crawlspace, S-Blaster goes wherever you do—no rigging or relocation required.

The system uses a finely controlled stream of plastic blast media through a masking locator cup to expose the fastener head. Blast zone is contained, media is vacuumed back, and debris is separated—clean air is expelled through a HEPA cartridge.

Use the E Drill’s built in “Build Fastener” tool to generate initial electrode size and cut depth based on engineering drawing dimensions. For precision-tuned settings tailored to your operations, email info@ppedm.com with your fastener details and we’ll assist you further.

Absolutely! We encourage sending samples. We have a full testing and microscopy lab to fine‑tune performance and validate results.

Absolutely. We feature numerous customer wins and success stories in our Newsroom – Customer Wins section. Plus, additional case studies are shared privately with potential customers. Contact us if you’d like access to those details.

Standard configuration covers fasteners from 3/32” to 3/8”, with other options available for larger fasteners. For larger or non-standard fastener sizes, please contact us for more information.

No—we don’t sell fasteners. However, our fastener database provides many part numbers and examples of fasteners that the E-Drill can remove.

S-Blaster is a handheld precision spot blasting tool for removing paint, sealants, fillers, corrosion, and coatings from fastener heads—without damaging nearby surfaces. It recycles media in a closed-loop system with HEPA filtration, minimizing mess and environmental impact.
