3/16" X 5/8" X 2" Carbide End Mill, 4 Flutes for Drilling Set of 4 – Drill Bits Sets for DIYers & Professionals

SIZE: Cutting Dia: 1/4", Shank Dia: 1/4", Length of Cut: 3/4" and Overall Length: 2-1/2". Packing includes 4 pcs set
APPLICATION: This tool can be used on copper, copper alloys, cast iron, steels, carbon steels (HB~225), alloy steels (HB225~325), pre-hardened steels (up to HRC~45), hardened steels(HRC40~45).
PERFORMANCE: The material is K200 ultrafine micro grain carbide. It is equipped with ultrafine particles of special trace elements, which is suitable for efficient cutting, low speed heavy cutting and other processing methods. When it comes to stainless steel or heat-resistant alloys, such as titanium based and Nickel Based Alloys, they have excellent performance.
4 FLUTE CUTTER: It has a unique geometric shape and powerful cutting edges. 4 flute is great for speedy cutting and are also particularly suitable for planar, stepped, grooved, and formed surfaces, while the 30 degree helix design can achieve smooth surface finish and better chip removal control than those with lower helix degree.
