Spyder Spyder Mach-Blue Metal Drilling Bundle

"Mach-Blue Metal Drilling Bundle includes the Mach-Blue 10-piece drill bit set + Mach-Blue 9-step drill bit + Mach-Blue 13-step drill bit. Spyder Stinger Mach-Blue armor-plated high-speed steel (HSS) drill bits are high performance metal and wood drilling bits that provide exceptional drill bit quality and durability, drilling performance, and value. The Mach-Blue Armor Plating combined with the advanced M-series alloy tool steel construction and proprietary heat treatment make these bits truly revolutionary - they retain sharper cutting edges for longer, have reduced heat build-up and cutting friction, and increased durability, rigidity, and breakage resistance. The impact rated 1/4-in speed hex won’t slip in conventional 3-jaw chucks making them well suited for use in quick change impacting power tools. The optimized self-centering split point cutting geometry won’t walk or wander – even on pre-hardened or curved surfaces. Ideal for drilling wood with nails, stainless steel, mild steel, aluminum, stacked materials and other tough to drill alloys. The Mach-Blue 10-piece drill bit set includes 1/16, 5/64, 3/32, 1/8, 5/32, 3/16, 7/32, 1/4, 5/16, 3/8-in bits with case. The Mach-Blue step drill bits are incredibly durable allowing for consistent drilling of a wide range of holes with a single bit. They’re especially ideal for electrical work and other applications in sheet metals, including enlarging existing holes making them the pro's choice for precision drilling, extended bit life, and value. The 13-step drill bit drills holes from ranging from 1/8-in to ½-in and the 9-step drill bit drills holes from ¼-in – ¾-in. Made in the USA. "
