Over 90 years ago we were established in Detroit Michigan by Heller Brothers File Company of Ohio to service the automotive, aircraft and light or heavy manufacturing industry in re-sharpening metal working hand files. Detroit was picked because it was the central manufacturing hub for the “Big Three” automotive production plants with support of other manufacturers including Tool & Die, Die and Mold, and General Machining.

As the USA manufacturing industry expanded and adopted new technologies so did SFS Carbide Tool. In the early 1950’s, we expanded into making machining cutting tools for the automotive and aircraft industry. These included not only the “Big Three” and their tier auto parts manufacturing suppliers, but also the “Aero Space” and ever expanding airplane manufacturing industries.

A new company named “MISCO” (Michigan Investment Steel Casting Company) was started in Detroit and has continued to expand alongside SFS Carbide Tool for over nine decades. We continue to service the tooling needs of major companies in the Aircraft, Automotive, Precision Machining, Graphics signage, NASCAR and performance engine building industries worldwide.

We manufacture a variety of taper tools with small tip diameters and various degrees of taper to open air way passages on trailing edges of turbine blades and vanes. The tip diameters could be as small as 0.010. Special end mills with special geometry are also used for CNC machining jobs.

We make carbide burrs, end mills, drills, step drills, reamers, and multi-diameter step tools, both solid and coolant fed. Please provide us with a blueprint or detail sketch to quote your requirements. A complete resharpening service is also available. We can sharpen dull cutters regardless of the manufacturer. This is an excellent and efficient way to get new tool performance at a fraction of the cost.

We make custom port cutting tools

PORT CUTTING

Cylinder porting is one of the most difficult machining jobs. But it is especially important to the engine shops that build the 700-plus horsepower engines for NASCAR and other professional racing teams. Horsepower, torque and acceleration are the keys to winning a race; refining the art of porting can give a team the edge they need to win. It all begins with choosing the right machining tools to blue-print the engine block cylinders, heads and manifold to exacting standards.
