The stainless steel milling range from Dormer Pramet (Elgin, IL) offers versatility and productivity. Insert styles include OEHT (octagonal), REHT (round) and XEHT (wiper). The versatile design of the double-positive 45-degree milling cutter (S450E) allows the same cutter body to be used with both octagonal inserts for face milling and round inserts for face/copy milling applications as well as supporting internal coolant delivery.
Suitable for use on machines with limited power, the inserts and cutter deliver high metal removal rates with low cutting force and reduced chatter.
It features positive axial and radial face angles for good cutting action and directing chips away from the workpiece. Available in a variety of diameters, the S450E performs well with fragile workpieces, unstable fixturing and for preventing stainless steel work hardening.
Using eight cutting edges, the highest number available for positive inserts, the OEHT (octagonal) insert features four new sharp, positive geometries for various cutting conditions:
- MF is for finishing applications in stainless steel, mild carbon steel and non-ferrous metals.
- MM is for machining stainless steel in medium cutting conditions.
- M with stabilizer is suitable for difficult cutting conditions in materials such as carbon steels and harder stainless steel.
- FA is for finishing and light to medium machining of nonferrous materials.
The geometries offer reduced cutting forces and increased durability for machining with or without coolant.

Backlog of Orders Index Grows To All-Time High
The manufacturing economy continued its recovery in March, according to Institute for Supply Management’s March 2021 ‘Manufacturing ISM Report On Business.’ Backlogs are growing, as are raw materials inventories and exports and imports.
Recovery Takes Hold: February U.S. Manufacturing Technology Orders Increase Almost 18% Over January
Totaling $377.6 million, February’s latest orders represent a 32.2% increase year over year, according to AMT’s report. Oil and gas surprised with an uptick, and medical equipment’s rise likely resulted from hospitals catching up on elective procedures.
