112 Type Single-Head Stepped Diamond Drill Bit

Type 112 Single-Head Stepped Gun Drill: Precision Multi-Diameter Drilling in One Operation The Type 112 Single-Head Stepped Gun Drill is a revolutionary tool engineered to produce precise, concentric stepped holes in a single, continuous operation. By integrating multiple diameters into one solid carbide body, it eliminates the need for multiple tool changes, secondary operations, and realignment. Covering a diameter range from 2.000 mm to 51.200 mm, this advanced tool is designed for superior chip evacuation and optimal cooling, featuring either a kidney-shaped channel or dual coolant holes based on diameter. It represents the pinnacle of efficiency and accuracy in our line of Solid Carbide Gun Drills. Product Overview This specialized stepped gun drill is the ultimate solution for components requiring multiple, concentric bore diameters along a single axis. Machined from a monolithic piece of high-grade solid carbide or with a brazed solid carbide tip (depending on configuration),…
