Yunnergo HSS Annular Cutter Set 13Pcs 7/16" to 1-1/16" Cutting Diameter, 6Pcs 7/8"- 2" Cutting Diameter, with 3/4 Inch Welded Shank, Mag Drill Bits Kit CNC Machined Cutters (2" Cutting Depth,6Pcs)

Brand: Yunnergo

Features:

• Material: Made of M2AL high speed steel (HSS), compared with ordinary carbon steel drill bit, stronger hardness, higher toughness. The products are heat treated and have a hardness range of HRC 65-67, which allows the drill bit to easily handle higher hardness metal materials with excellent hardness and stability.
• High Temperature Capability: M2Al annular milling cutter maintains its hardness and cutting effectiveness at high temperatures. This high temperature capability makes the bit difficult to anneal when working at high speed and temperature conditions, maintaining a stable cutting ability. This is particularly important in high-intensity and high-speed drilling tasks.
• Cutting Efficiency: Steel hollow drill has a sharp cutting edge and good chip evacuation ability, so that it has a high cutting efficiency in the drilling process. The sharp cutting edge can quickly cut into the material, no burrs, making the hole smooth, and the good chip evacuation ability can quickly clear the chip upward, avoid the chip blockage, and keep the cutting process smooth.
• Strong Versatility: This annular cutter set compatible with many brands of magnetic drill, can also be used for drilling machines, CNC lathes and other equipment cutting, grinding, precision machining and other fields, and suitable for a variety of materials, such as steel, iron, aluminum, copper, plastic, wood, stone and so on. Note: If you want to use this ring knife on a drill press, you will need an additional ring knife shaft to match.
