Features & Benefits Complete 12-piece precision drill set Drill sizes from 0.5 mm to 1.6 mm Uniform 3/32" shank on every drill Precision-ground cutting surfaces Tungsten vanadium steel construction Uniform shanks make changing between drill sizes faster and easier Suitable for precision drilling and detailed workshop applications Busch quality Made in Germany Specifications Specification Details Brand Busch Product Type Precision Drill Set Number of Drills 12 Drill Size Range 0.5–1.6 mm Shank Diameter 3/32" Material Tungsten Vanadium Steel Head Shape Drill Head Sizes Assorted SKU 18.163 MPN 18.163 UPC 014891168244 Country of Origin Germany 12 Graduated Drill Sizes The set covers 0.5 mm through 1.6 mm, providing a useful selection of fine drill diameters in one compact assortment. With 12 sizes across this range, you can select a drill appropriate for the hole diameter required instead of trying to make one drill size work for multiple applications. Uniform 3/32" Shanks Although the cutting diameters vary, every drill has the same 3/32" shank diameter. This is particularly convenient when working through several drill sizes during the same project. Once your compatible handpiece, chuck, or collet is set up for a 3/32" shank, you can move between drill sizes without having to accommodate a different shank diameter each time. The uniform shank also provides a much more substantial gripping surface than the extremely small cutting diameter of the finer drills. Precision-Ground Tungsten Vanadium Steel Busch manufactures these drills from tungsten vanadium steel and precision-grinds the cutting surfaces for accurate performance and durability. They're designed for precise drilling and can be operated at lower speeds, making them well suited to controlled detail work where accuracy is more important than aggressive material removal. Made for Fine, Controlled Drilling With cutting diameters beginning at just 0.5 mm, this assortment is especially useful when standard workshop drill bits are simply too large. The graduated sizes make the set a practical addition to a jeweler's, model maker's, repair technician's, or precision craftsperson's tool collection.
