Pricing and Order Information

Starting at $25 cart minimum and $1.25 per part

Tumbling prices start with a $25 cart minimum and $1.25 per part. No minimum quantities are required! Bulk discounts begin when you add at least one identical part! Upload your file below to get instant pricing.

If you’d like multiple finishing services applied to your parts, such as anodizing + tumbling, please submit a custom quote request. Our team will evaluate if your parts are good candidates for combined finishing services and send you a quote!

Materials Available

Tumbling is available on a variety of materials at a minimum of 0.125″ thickness

Geometry Requirements

As with all of our services, parts must meet certain requirements to qualify for tumbling. 

Minimum parts size:  0.5″ x 1.5″ 

Maximum part size:  4″ x 7″

Material minimum thickness: 0.125″

These are general size requirements for tumbling. Please keep in mind that thin or fragile parts are not ideal for tumbling and may bend during the tumbling process. For thin and fragile parts, linear deburring is ideal.

File Setup

If after reading these guidelines you’ve found you need to make some changes to your part design, check out our tutorials for designing and preparing your files in Illustrator, Inkscape, and Fusion 360.

What to Expect From Finished Parts

  • Fragile geometry is not recommended, unsupported pieces will bend during the tumbling process
  • We cannot guarantee a consistent and uniform finish, especially between separate orders.
  • Edge softening cannot be precisely controlled.
  • Holes and interior cutouts smaller than 1/2″ will not be processed completely.
  • The finish will not be cosmetically perfect. This process is for deburring and edge softening only.
