Arno-Rouse has incorporated existing cut-off support blades into a gang tooling concept. Designed for screw machines, the tooling features 0.625" round shanks and 90-degree angles in both right- and left-hand configurations. The tooling can cut off barstock ranging to 1.180" (30 mm) in diameter with a 2- or 3-mm-wide insert. According to the company, if a support blade breaks, it can be replaced easily and quickly—the holder doesn’t need to be taken out of the machine to replace the support blade or insert. The tooling is available in six carbide insert grades and various geometries for virtually all materials, the company says.
Running rotary milling cutters at the proper speeds and feeds is critical to obtaining long tool life and superior results, and a good place to start is with the manufacturer's recommendations. These formulas and tips provide useful guidelines.
Consider these alternatives when conventional drilling can't do the job.
The more common twist drill point geometries often are not the best for the job at hand. By choosing the best point for the material being drilled, it is possible to achieve better tool life, hole geometry, precision, and productivity.
