Milwaukee Gradual cobalt drill 4-20 mm

The gradual cobalt drill from Milwaukee is a highly advanced step drill designed for precise and efficient drilling in various types of metals, including steel and stainless steel. With a diameter range of 4 to 20 mm, this drill offers remarkable versatility for different applications. The innovative aluminum-chromium-nitride (AlCrN) coating significantly increases its lifespan, which can be up to ten times longer than that of conventional step drills. The special geometry of the cutting edges and steps allows for smooth performance without clogging, minimizing the risk of mechanical issues and preventing material deformation during drilling. The drill features a RAPID STRIKE TIP™ that enables precise centering without the need for pre-drilling, further enhancing efficiency. The 3-flat shank ensures optimal grip in the chuck and guarantees maximum power transfer. - Aluminum-chromium-nitride coating for up to 10 times longer lifespan - RAPID STRIKE TIP™ for precise centering without pre-drilling - Optimized geometry to avoid clogging and material deformation - 2-flute geometry for up to 2 times faster drilling speed - 3-flat shank for maximum grip and power transfer.
