Since 1981, Services For Plastics, Inc. has manufactured Rotor and Bed blades for all makes and models of Grinders. With hundreds of different types and styles of blades in stock, we have one of the largest inventories of readily available shipping stock in North America. SFP stocks all major Grinder models and sizes of blades, and we can provide same day shipping on all in-stock items.

If the make and model of your Grinder is unknown, send us a sketch or hard sample, and we can reverse engineer and design a suitable replacement blade. We can custom manufacture any type of blade and provide better than OEM replacement blades per your specification for precise compatibility. All SFP blades are made from Premium Heat Treated D-2 tool steel and match ground for superior accuracy.

Our precision grinding technology, EPIC Sharp® Edges, provides for better and more consistent pellet size regrinds and minimizes fines and coarses to improve your overall granulating process. Our superior dimensional accuracy and manufacturing tolerances, make SFP Blades better than any other blade available on the market. The EPIC Sharp® Edge of our blades retains its sharpness longer due to our state-of-the-art match grinding process.

SFP offers five (5) EPIC Sharp® Edge styles and blade design profiles:
Keen Edge, Reverse Bevel, High Sheer, Reverse Bevel High Sheer and Hook configurations.

For extreme high wear applications, an ultra wear resistant tungsten carbide coating, over the premium D2 tool steel, is also available. Talk to one of our blade specialists about your specific application, and we will custom tailor a design to best fit your granulating needs.

SFP also offers complete resharpening services, so you can always have a set of sharp blades on hand. We take your old worn out blades and custom match grind them back into usable sharpened blades. In addition, SFP manufactures a complete line of all Grinder parts for repair and refurbishment of your Grinders. Grinder screens and even the rotors that hold the blades are available.

Services For Plastics is your single source for all your Grinder blade and screen needs!
