PCD Cutting Tools - Metal Cutting Tools

LMT Onsrud LP makes integral-shank Metal Cutting Tools at its suburban Chicago tool manufacturing and customer service facility, for firms ranging from small machine shops to large manufacturers in the automotive, aerospace, medical and other industries. Our metal cutting tools are the product of innovative design, the finest raw materials and coatings, and state-of-the-art manufacturing methods and equipment. Choose from our large inventory of standard tool types, sizes and styles, or take advantage of our ability to design and build a tool tailored to your specific job requirements.

End Mills

Onsrud offers a line of solid carbide, 4-flute, roughing end mills and 6-, 8- and 10-flute finishing end mills, designed primarily for deep pocket milling of titanium, stainless steel, Hastalloy, Inconel and other difficult-to-machine exotic metals. Our roughing end mills are optimized for high metal removal rates and incorporate a variable flute indexing feature that reduces chatter. Our finishers produce accurate parts with superior surface finishes that meet, or exceed, demanding aerospace specifications. These exotic metal end mills are available with an AlTiN coating.

Newest addition to our line of exotic metal end mills is a solid carbide 5-flute end mill that permits higher feed rates for slotting, profiling and semi-finishing operations in titanium, stainless and other exotics. It is made from nanograin, high-transverse-rupture-strength carbide for long life in demanding applications and incorporates the variable flute indexing feature. The line comes in a large range of corner radii and neck and flute lengths.

For cutting aluminum, Onsrud offers solid carbide 2- and 3-flute end mills in standard, medium, long and extra-long lengths. Our Aluminum End Mills are available in an extensive range of corner radii and neck and flute lengths and are available in through-coolant versions.

Routing Tools

Onsrud is a leading supplier of small-diameter, high-rpm routing tools used on CNC routers, milling machines and machining centers for the machining of aluminum stacked sheet, plate and extrusions. Our newest offering is a solid carbide O-flute routing tool designed expressly for optimal cutting of soft aluminum alloys, such as 3003. Its large, open flute design allows the chip to be thrown clear of the cutting zone. The large rake angle of the tool's cutting edge gives it a more pronounced shearing action that reduces the amount of cutting heat generated.

Our single-flute Spiral O-flute for Aluminum routing tool is available in upcut and downcut versions. The tool can be ordered with a ZrN coating that prevents build-up of aluminum on the cutting edge and the flute so that the tool runs cooler, stays sharper longer and lasts longer.
