Product Details
The fast spiral drill bit is designed for high feed rate applications under low spindle speeds, particularly effective for drilling soft materials such as aluminum. It is suitable for operations involving low tensile strength, softer materials that can complicate chip removal, including softer ferrous metals and alloys like soft steels and soft cast iron, as well as non-ferrous options such as aluminum, magnesium, copper, and zinc alloys. The drill features a combination of fast spiral and high helix angle with wider flutes, promoting efficient chip movement and ejection, compatible with handheld manual drills and both portable and stationary machine tools. Optimal performance is enhanced with lubricating cutting oils or appropriate coolant fluids. Key features include a right-hand (clockwise) cutting direction, a standard two-flute design with wider flutes, a helix angle of 34° to 40°, and straight shanks matching the drill diameter. The length of each drill varies according to the specific diameter, balancing overall rigidity and depth capacity. The drill is manufactured from high-speed steel, with precision ground flutes, cylindrically ground, general-purpose design for soft materials, a 118° point angle, standard web thickness, and a bright finish.
