3.175 x 2mm Left-Hand Down-Cut Double Flute End Mill 4-Piece Bundle
This bundle of left-hand down-cut end mills includes four end mills with a shank diameter of 3.175mm, a cutting diameter of 2mm and various cutting depths of 6, 8, 12 and 17mm.
The “down-cut” spiral bit flutes are designed to cut from the top surface down, leaving a smooth edge at the surface. It pushes down on the material being cut, and helps hold the material in place on the table surface. Some operators like this bit as it packs the sawdust in the groove being cut, this helps hold parts in position and helps maintain vacuum when that type of hold down system is used. Disadvantages are the packed sawdust is not removed by the dust collector and must be scraped or brushed off manually. Also this bit is not appropriate for thermoplastics as the "packing" of the dust re-welds the parts together. When making "through cuts" the down cutting force can splinter the bottom face of veneered or other susceptible materials
