Steel Balls

Multipurpose Low-Carbon Steel—Low-carbon steel balls are our easiest steel balls to machine. They are often used for parts that don’t require high strength, such as knobs. These balls can be surface hardened with heat treating for added wear resistance.

Wear-Resistant 52100 Alloy Steel—High carbon and chromium content makes this 52100 alloy steel extremely hard and resistant to wear. It’s also known as chrome steel. Often used as bearings, these balls are hardened for increased abrasion and impact resistance.

Tight-Tolerance Wear-Resistant 52100 Alloy Steel—The diameter of these balls is held to a precise tolerance. They’re made from 52100 alloy steel, also known as chrome steel, which has high levels of carbon and chromium to make them extremely hard and resistant to wear. Often used as bearings, these balls are also hardened to increase their abrasion and impact resistance.

Shock-Resistant S2 Tool Steel—This S2 tool steel has been hardened for excellent strength and impact resistance. It has a tough core that resists breaking under shock loads.

Abrasive Blasting Media

Remove paint, coatings, and rust or add texture to surfaces. This media is suitable for use on a wide variety of surface materials.

Our abrasive blasting materials are sorted from least to most aggressive. The more aggressive the media, the more material it removes from your surface.

Both particle mesh size and grit measure the size of the abrasive particles. The higher the number, the finer the particles are.

Steel Shot

The most common abrasive for heavy duty cleaning and peening jobs. Rounded like glass but harder and denser, this shot blasts away heat-treated scale, heavy forgings, and other stubborn irregularities while leaving a uniformly peened finish. It also lasts for 500 times more cycles than glass, so it’s perfect for abrasive blasting cabinets and other systems that let you reuse your media.

High Reusability—Effective for hundreds of cycles under normal blasting conditions.

Steel Cut Wire Shot

A tougher alternative to steel shot. Cut from cold-drawn solid steel wire for extreme durability, this media stays effective for twice as many cycles as steel shot. The cutting process forms both rounded and sharp sides, so it will peen and etch your surface at the same time. It also creates highly consistent pieces for a uniform finish.

Very High Reusability—Effective for thousands of cycles under normal blasting conditions.

				10 lb.		25 lb.
Particle Mesh Size	Grit	Recommended Blast Pressure, psi	Reusability		Each		Each
14-25	24	60 to 100	Very High	6075N31	0000000	6075N32	0000000
16-30	30	60 to 100	Very High	6075N21	000000	6075N22	000000
18-40	36	60 to 100	Very High	6075N11	000000	6075N12	000000

Steel Grit

A more aggressive alternative to steel shot, steel grit blasts harder and leaves a rougher finish thanks to its sharp, angular edges. It digs below the surface to remove material, which is why it’s commonly used to strip paint, remove rust and scale, and prep surfaces for coatings to bond to. However, you should only use it on steel and iron surfaces because it will leave iron behind that could contaminate other materials.

Medium Reusability—Effective for dozens of cycles under normal blasting conditions.

Ball Bore Gauge Sets

Keep over two dozen different ball diameters on hand to check bore sizes or use as go/no-go gauges. For accuracy, they’re precision ground to tight tolerances. These sets include two balls for each diameter, so you can cross-check accuracy, measure multiple spots at the same time, or swap them out after they wear. They're often used to test engine cylinders, machine components, and turbines where deviations in roundness or size can lead to wear. You can also use them to find the taper of a bore or the diameter of a countersunk hole.

To find your bore’s ID, set a ball that’s slightly smaller than your bore into the hole. With a measuring tool, determine how big the gap is between the ball and the edge of the hole. Add that measurement to the ball’s diameter to calculate the ID.
