Introduction
This document introduces the new HM roughing mills, model "SMW 4404", designed for high feed machining with specially strengthened cutting edges. The mills feature irregular helix angles for enhanced performance.

Specifications
The roughing mills are available in diameters ranging from Ø6 to Ø20 mm. They are made from micrograin HM and have a DIN 6535 HB shank, conforming to DIN 6527 medium type standards. The tolerance range for D and d is h10 and h6, respectively.

Coating and Hardness
The mills are coated in black and have a hardness of 42 HRC.

Product Range and Pricing
The document lists various models of the SMW 4404 series with their respective dimensions and prices. For example, the SMW4404.060.N00 model is priced at €72.

Machining Parameters
The document provides detailed machining parameters, including cutting speed (Vc), tooth feed (fz), feed per revolution (fn), and feed speed (Vf). These parameters vary based on the diameter of the mill and the material being machined.

Applications
The mills are suitable for a wide range of materials, including non-alloy steel, low alloy steel, high alloy steel, stainless steel, cast iron, aluminum, copper, plastics, high-temperature alloys, titanium, hardened steel, and graphite. Recommended and possible applications are specified, with a note that shoulder milling parameters should be increased by 20% for optimal performance.
