Product Description

The YG-1 E1004 uncoated high-speed steel miniature double-end square nose end mill has four flutes, varying helix angles depending on tool size, and a center-cutting design for finishing precision components on steel, stainless steel, titanium, titanium alloys, hard brass and bronze, copper, plastic, wood, aluminum, and aluminum alloys. The tool has small cutting and shank diameters, allowing better control over the size of the cut than larger tools when creating precise details and contours. The double-end design has cutting edges on both ends, allowing a new cutting surface to be substituted when the first shows wear, which doubles the tool’s life compared to single-end square end mills. Four flutes produce a better finish than fewer flutes. The tool’s square end creates sharp, unrounded cuts. The center-cutting design has cutting teeth at the end of the tool, so it can be fed into the workpiece like a drill bit.
End mills with a cutting diameter up to 3/32'' have a 39-degree helix angle, which provides more support behind the cutting edge than higher angles, and increases cutting action and chip evacuation compared to the standard 30-degree helix. It efficiently cuts difficult-to-machine material, moving it up the spiral and away from the workpiece. End mills with a cutting diameter of 7/64'' or larger have a 30-degree helix angle, which balances lower angles’ strong cutting edge for difficult-to-machine materials with higher angles’ increased cutting action.
High-speed steel (HSS) is a common general-purpose steel for cutting tools and is compatible with a variety of materials. With no coating or surface treatment, it features just the base material to help the miniature tool retain its sharp edges and tight tolerances. Cutting diameter tolerance is + 0.0010 to - 0.0000'' for end mills with a different shank and cutting diameter and + 0.0000 to - 0.0015'' for end mills with the same shank and cutting diameter. The round shank accommodates a range of tool holders.
End mills are designed to remove material and create multi-dimensional shapes and profiles. They have cutting edges along the outside diameter and flutes that remove chips from the cutting area and allow cooling fluids to enter. If heat is not reduced effectively, the tool’s cutting edges will dull and additional material buildup can occur. The number of flutes can range from two to eight. Two-flute designs offer the most efficient chip removal, but more flutes provide a smoother finish. The shank is the end of the tool held in place by a tool holder or machine. Center-cutting end mills can create three-dimensional shapes and profiles, and make plunge cuts similar to a drill bit. Non-center-cutting end mills are for applications such as peripheral milling and finishing, but cannot make plunge cuts.
