Stainless Steel Tumbling Pins by guntap is the best tumbling media to clean, deburr, and burnish metals. Ideal for handloaders who use a rotary or magnetic tumbler and want their brass cartridges to be sparkling clean inside and out. The media can be used with brass cases with any primer pocket or flash hole size without fear of having stuck pins.

Detailed Product Information and FAQ

Created from extremely tough 302/304 stainless steel, these pins will last for thousands of cleanings. The pin dimension was specifically designed such that the pins will not get jammed sideways or side-by-side in the primer pocket or flash hole.

However, it is possible for pins to get jammed sideways in certain brass cartridges. Because there are hundreds of different brass cartridge specifications, it's not possible to design a pin that works with every cartridge. Best practice is to always inspect your cartridges prior to loading.

Q: How do I use these stainless tumbling pins?

A: Place the stainless steel tumbling media in a rotary or magnetic tumbler, along with water, detergent (we recommend Brass Shine), and brass cartridges or other metal parts. The amount of water needed varies, but start with 1/2 drum full and adjust for future cleanings.

Run until clean, typically between 30 minutes and 2 hours. When first starting out, check every 15 minutes to see if additional cleaning is necessary. Use with Brass Shine Powder Detergent for best results. Do not exceed the tumbler’s maximum weight capacity otherwise premature motor failure may occur.

Q: Will these pins work in a vibratory tumbler or ultrasonic cleaner?

A: These pins are designed for rotary and magnetic tumblers. They are not recommended for vibratory tumblers, but some customers have successfully used them in such tumblers. These pins will not work in ultrasonic cleaners.

Q: How much tumbling media do I need for my tumbler?

A: For a 15 pound/1 gallon drum (e.g. Thumler's Model B), 5 pounds of pins are needed to clean your items quickly and efficiently. For a 3 pound/1 quart drum (e.g. Harbor Freight Item 67631), 1 pound is sufficient.

More pins may slightly speed up the process, but using too many pins can potentially cause poor cleaning performance or prematurely burn out your motor. If you have a custom tumbler, send us a message or call us at Contact Us for advice on how many pins are correct for your application.

Q: This is too much/not enough media for my tumbler. Do you sell in other sizes?

A: This listing is for 5 pounds of stainless pins. Click here for the many different sizes we sell. If there's an amount you need that we don't have listed, let us know and we'll custom package it just for you!

Q: Will I need to buy more pins in the future?

A: Stainless steel pins will not rust, fracture, or breakdown during the tumbling process. They are very small, with a length of 0.255" (tolerance ± 5%) and diameter of 0.047". The only reason you buy more pins is to replenish the ones you lose (which is inevitable).

Q: Are these pins magnetic? I thought only 400-series alloys were magnetic.

A: These 302/304 stainless steel pins are magnetic. The process by which it happens is called Martensitic Stress Induced Transformation (MSIT). This allows you to easily separate and pick up the pins with a strong magnet. We recommend using a rare-earth neodymium or large coated ceramic magnet to capture all the pins that fall out of the tumbler.

Q: How far should I process my brass before cleaning?

A: It's best to only deprime your brass (and chamfer military brass) prior to cleaning. You can size your brass prior to cleaning, but you will want to resize after cleaning to ensure any small deformations that may occur during cleaning are eliminated.

Q: What else can these pins be used for?

A: Although this specific pin dimension was designed for cleaning brass cartridges, it can be used in many different industrial and jewelry applications, such as deburring, burnishing, and cleaning parts made from cast iron, titanium, steel, aluminum (430 alloy recommended), and other metals. Be sure the hardness of 302/304 stainless will work for your application and not damage your parts, especially when made from aluminum or other soft/precious metals.
