Holepop EDM Supplies & Electrodes is an EDM (Electrical Discharge Machining) supply company, providing a variety of electrodes and guides. For more than 15 years companies in aerospace, biomedical technology, tools and dies, and defense have used our electrodes and guides to create their cutting-edge products.
Given the choice between us and our competitors, many companies have chosen us as their EDM supplier because we are a supply chain management company, not an ordinary parts distributor. We deal with all of the headaches of the parts procurement process, so that you can devote your financial and human resources to other things.
Our value-added processes include design, execution, control, and monitoring. If you have a machining objective, but no concrete specifications for the electrodes or guides that you need, or if you have to work with EDM drill settings that cannot be deviated from, this is where our design team comes in. Working in close cooperation with your engineers, machinists, procurement staff, and production manager, we make sure that your parts are just what you need to get the job done. If you have a very predictable production schedule, our stocking system ensures that we have your parts stocked ahead of time, in anticipation of demand. This minimizes lead times and the need to plan your production schedule around us. If you have a very high and uncompromising standard of quality, our quality assurance system ensures that no product leaves our facility that does not meet your standards. We inspect all dimensions of our electrodes with metrological instruments whose accuracy reaches up to the fifth decimal place.
With brass, copper, copper-tungsten, and tungsten carbide electrodes, guides with conventional ceramic, ruby, or silicon nitride guiding surface cores, drill chucks, and dielectric fluid, we carry all of the essential consumables needed for small hole EDM. All of our products are customizable, and we make sure that you find the parts perfectly suited to the application at hand.
Brass is best used for tool and stainless steel, titanium, carbon, invar, aluminums and work-hardened materials that have been heat treated so they cannot easily be machined.
Copper is used best on exotic types of metals such as tungsten and carbide, as these metals are extremely hard and cannot be machined or drilled through using conventional type drilling.
Tungsten carbide is a relatively exotic material with great rigidity and toughness, giving it two advantages over brass or copper—greater penetrative power and smaller potential diameter.
Copper-tungsten combines the strengths of copper and tungsten, and is more effective than copper or tungsten where their applications overlap.
Silver-tungsten is unmatched when it comes to a smooth surface finish.
Affordable, readily-available guides in standard sizes. Best for machine shops that tackle a wide variety of jobs that aren’t out of the ordinary.
Totally customizable guides with the best guiding surface material on the market. Silicon nitride minimizes friction to maximize lifespan.
Chucks provide a tight and precise grip for electrodes. Keyed, keyless, and collet chucks for all budgets and applications.
Dielectric fluid lets electrodes perform at their best. Oil-based and synthetic dielectric fluids with low aromatic content and high flash points.
