RUKO KEB-HSSCo 17.0mm Quick-In Twist Drill Bit

Drilling large-diameter holes in tough metals demands a bit that stays sharp and centered. The RUKO KEB-HSSCo 17.0mm Quick-In twist drill bit tackles steel, stainless steel, and cast iron with a 5% cobalt HSS body that resists heat and wear. Its 135° split point bites instantly without wandering, and the Quick-In shank clicks into compatible chucks for fast bit changes.
