Unique Bargains 2pcs Carbide End Mills 4-Flute 13mm / 0.51-Inch High-Speed Steel CNC Milling Cutter Bits Tool with Straight Shank for Aluminum Steel Cutting Metalworking

Made of high-speed steel with straight and round shank, these end mills feature high hardness, strength, deformation resistance, heat resistance, and wear resistance for accurate and clean cuts in CNC and manual milling machines.

Helical design enhances chip evacuation and reduces heat buildup, while the four cutting edges enable faster material removal than 2-flute end mills for high-volume and high-speed machining.

End milling bits are used for cutting metal, plastic, and wood to create parts and components through operations such as face milling, slotting, profiling, and drilling.

Always wear appropriate protective gear including eye and hearing protection when using these tools.

Consider using coolant or lubrication to prolong tool life depending on the material being machined.
