1/8 x 3/8 x 3/8 x 2-5/16 - 2 FLUTE REG Single End HSS ENDMILL - ID: 699-1039
Use the Part # to find the dimensions in the chart below
Tool Material
High Speed Steel (HS): HSS is a baseline tool steel used for many basic machining applications and for short runs on older milling machines.
However, it does not offer the speed and feed advantages of HSS-Cobalt and Carbide tools.
Cobalt: With a typical cobalt content of 8 percent, this tool is usually priced a bit higher than standard HSS.
It allows for increased speeds and feeds because of greater hardness, though it still falls far short of the speed, feed, and durability advantages of carbide.
Length: Select an endmill that is as short as possible to minimize tool deflection during the milling operation. Select stub lengths, if possible, to save on tool cost.
- Long Length - Used
Number of Flutes: More flutes reduce chip load and improves surface finish if feed rate remains the same. The most common flute numbers for general milling
operations are two (maximum space for chip ejection) and four (better surface finish). 2-Flute - Allows maximum space for chip ejection. Used for general milling operations and on softer metals.
- 6 & 8 Flute - These larger number of flutes reduces chip load and can improve surface finish. As such these tools are excellent for putting the the final finish
- on the application, and removing any rough spots from previous milling.
Certain materials respond better to various flute configurations. Below is a chart to help you decided what number of flutes is best for the material you are milling.
