IRWIN 3016009 9/64" Diameter Drill Bit, Spiral Flute

Get reliable, precision holes in steel and other hard metals for mounting and installation projects. The IRWIN Tools 3016009 9/64 in cobalt twist drill bit (3-pack) is built for trades and security installers who need consistent, long-lasting performance. Cobalt-enhanced HSS construction provides superior heat and abrasion resistance so bits last longer during heavy metal drilling, while the 135° split-point tip starts immediately and prevents walking on flat surfaces. The spiral flute geometry evacuates chips efficiently to maintain cutting speed and reduce heat build-up, and the straight shank gives stable, wobble-free engagement in standard chucks. With a maximum length of 3 in and a precise 9/64 in diameter, this set is ideal for installing security cameras, surveillance housings, server racks, cable management brackets, and other monitoring or networking hardware. Keep installation timelines tight and minimize tool changes—order this dependable 3-pack to outfit your crew or service vehicle and get the job done right the first time.
