Carbide Inserts

Carbide inserts are indexable cutting tools used for machining steel, cast iron, and nonferrous metals. They allow for faster cutting, withstand high heat, and produce smooth, high-quality finishes.

Tool Holders

Whether you need a one-off custom tool or high-volume production, we can manufacture or repair tool holders from your print or sketch — no job is too big or too small.

Ceramic Inserts

Ceramic inserts are ideal for high-speed milling and turning. Tough and heat-resistant, they’re a top choice for demanding applications across various metalworking jobs.

PCBN/PCD Inserts

PCD inserts are perfect for abrasive, nonferrous, and nonmetallic materials. With ultra-sharp diamond tips, they deliver precision at high speeds and long tool life.

Regrinding

Save on costs by regrinding instead of replacing. We can adjust or replace holders to fit your reground inserts — call us to see what’s possible with your existing tools.
