Additionally, MAGNUM Drills offer: Superior strength and durability provided by M7 molybdenum high speed steel. More holes per drill than ordinary twist drills, especially in cordless power tools. These high-speed drill bits have a functional black and gold surface treatment that holds lubricants for smoother drilling and torsional strength. Meets NAS 907B aircraft specifications. 135ø split point for fast penetration and accurate starting without a center punch. Precision ground point, flutes, body, clearance and drill diameter for the ultimate in accuracy and performance. Body and clearance are gold surface treated for maximum lubricity.
