Solid Pilot Counterbore: 0.588in Dia, 0.39in Pilot, 4 Flutes is a precision cutting tool designed for machining holes using high accuracy and repeatability. Constructed from M2 High-Speed Steel with four flutes, the drill bit ensures fast removal of chips while maintaining straightness during use. Ideal for aerospace, automotive, or general engineering industries, it features a 1/4 inch pilot diameter to enhance centering accuracy and reduce skidding when drilling metals such as aluminum, stainless steel, cast iron, or titanium alloys. The cutting edge is hardened and treated with a black oxide finish for extended life, durability, and resistance to corrosion, making it an essential tool for both amateur and professional users.
