“Wonderful experience dealing with this company. I worked with Andrew Martinez and he was awesome! Helped me pick out the correct blades for the new K770 I was purchasing for a demo project involving steel beams and concrete. He answered every question I had and went above and beyond keeping me in the loop on my order. Going to put these Kong and Bulldozer blades to the test and I’ll be back. Thanks Andrew and ECS.”

Common Questions

Don’t see yours? Call 1-866-878-4213. We pick up.

All FAQs
How do I choose soft, medium, or hard bond?

Bond hardness is the opposite of what you’d expect. Harder, denser concrete needs a soft bond: it releases diamond faster to keep cutting. Soft, low-aggregate material or green concrete needs a hard bond to hold the segments longer. Medium bond covers most standard jobsite conditions.

When does my order ship, and what does shipping cost?

In-stock orders placed before 2pm PST Monday through Friday ship the same day. Orders after 2pm or on weekends ship the next business day. Shipping is free on every order to the lower 48; Alaska, Hawaii and larger freight orders are quoted.

Do you offer contractor or bulk pricing?

Yes. Call us at 1-866-878-4213 to discuss volume rates. Contractors with recurring orders or accounts over $5,000/year qualify for contractor pricing. Net 30 terms available for approved accounts.

Does OSHA Table 1 apply to my concrete crew?

If your crew cuts, grinds, or drills concrete: yes. OSHA’s silica standard requires engineering controls (HEPA vacuum + shroud, or wet cutting) for any task that generates respirable silica. We carry full OSHA Table 1 compliant dust and slurry systems. See dust management products.
