Downsizing Inserts

Your dull inserts can – AND SHOULD! – have another life.  Your company can save 40-60% or more of the cost of a new, smaller insert if you take advantage of downsizing.

When you send us your dull inserts, we grind them to the new smaller standard size or a special request size.

As you specify, we will:

  • Grind down one standard size or several
  • Grind chip breakers back into the insert
  • Complete new edge prep
  • Recoat with original or superior coating for your application

Our precision process removes all stock without heat, thermal cracking or chipping. Custom honing in our plant provides tool life that often exceeds that of the original insert. Your inserts are carefully packaged and shipped promptly to you. We downsize squares, triangles, rounds, hexagons, pentagons, 80 degree diamonds, 55 degree diamonds, grooving tools and many more.

You know the cost of indexable carbide inserts and you know they are ever-increasing!

Because the charge for regrinding is only a fraction of the cost of a new insert, it is not only economical for you to have your inserts reground – you’ll surely agree that it’s necessary. For example, a $10.00 insert might cost only $2.00 to sharpen and $2.50 to downsize, depending on the quantities involved. Also, many of our reground inserts last LONGER than the original due to our expertise in carbide grinding, edge prep and superior coatings.

It’s easy to use our service:

  1. You send us your scrap carbide and tell us your needs. Sometimes we can even arrange to pick these up at your facilities.
  2. We inventory the material received and formally quote firm prices for the grinding/coating of each item.
  3. You give us formal approval and instructions to proceed.
  4. We work on your order and return your high quality reground inserts in approximately two to four weeks. (faster turnaround is possible).

Our Business is Run by Perfectionists

That’s why we can guarantee our work 100 percent. You can be assured that your order will receive individual attention, whether it’s large or small. We welcome the opportunity to show you what makes us the best source for your insert work.
