In stock, ready to ship and competitively priced, Saturn Industries designs and manufactures both custom and standard EDM tapping electrodes with the end-user in mind; eliminating issues of centering, positioning and burring in the machining process. Only the skilled machinist, experienced with EDM will know all the variables affecting their machining process, but Saturn's unique and innovative electrode design has saved EDM machinists worldwide, countless hours of fabrication time.

So how do they do it? Three design modifications are the key!

• Round Shanks – our round shank design ensures that the electrode is centered in the chuck every time. This, in turn, allows dead center positioning on the workpiece to produce a more accurate thread.
• Timing Flats – The inclusion of a timing flat on the shank of the electrode ensures accurate and consistent lead thread positioning, saving time for the machinist by eliminating the need for manual positioning. This feature provides a significant cost savings benefit.
• Champhered Lead Threads – Yet another superior design standard, Saturn manufactures every tapping electrode with a champhered lead thread, which eliminates burrs and produces a clean lead thread in the workpiece.

Saturn keeps a larges quantity of standard sized orbital and non-orbital tapping electrodes in stock so their customers can realize a substantial cost savings. Many of Saturn's tapping electrodes also come standard with flush holes. A far better alternative to time-consuming manual flushing or messy external flushing methods. built-in flush holes create pressure and facilitate flushing of debris and sludge during the threading process.

Saturn can also custom manufacture tapping electrodes to the customer's specification.

Saturn's custom production capabilities include:

• Saturn can produce electrodes using practically any combination of special pitch diameters, pitches and thread forms.
• For mold makers, Saturn can produce special taps that take shrink factor into consideration.
• Saturn can mount threading electrodes on 20MM 3R shanks.

Standard sizes:

• English - from 0-80 (available only from Saturn) up to 1-14
• Metric - from M1.6x.35 up to M20x2.5

Available electrode materials:

• Copper Tungsten
• Brass
• Copper
• POCO EDM-3 Graphite
• POCO EDM C-3 Copper Impregnated Graphite

• Since 1959, Saturn has pioneered new technologies to produce the highest quality electrodes, inspecting each electrode on a pitch diameter to a tolerance of +0/-002. Saturn electrodes are straighter, have superior pitch diameter control and have better thread form, which means that when you buy a Saturn electrode, you can be sure that you've purchased the finest electrode available.
