Ingersoll Cutting Tools
A 4-in. Ingersoll Hi-QuadXXX facemill takes off more than 0.300 in. per pass to fully penetrate the heavy oxide crust in a 4140 steel forging. As a result, the tool edges last through a complete roughing sequence for a part, involving 6-8 passes. A previously selected tool needed indexing before completing even one pass.

Besides negative/positive cutting geometry, Ingersoll Cougar-Mill facemills feature improved, wedge-type seating that mechanically locks the inserts in place to better withstand heavy cutting loads. The cutters are available in standard diameters up to 14 inches.
Medfab Manufacturing in Lakeville, MN, completes this medical component in difficult-to-machine tantalum using Ingersoll T-Micro elliptical-shank boring bar. Extra rigidity of the bar permits faster metal removal and improves the as-machined finish. In its first application at this location, boring the ID of a titanium tube with a 4-to-1 aspect ratio, and walls as thin as a fingernail, the T-Micro tool completed the part faster, and with a 8- to 10-µ as-machined finish. With previous tooling every part required 15 minutes of hand polishing to reach surface-quality specs.
