Features
HSS construction provides heat resistance and longer tool life for metalworking and general drilling tasks across materials like steel, aluminum, and cast iron.
Large-diameter 1-3/8″ enables faster material removal and efficient hole sizing, reducing the number of passes needed for large holes when used with proper speeds and feeds.
4MT taper shank offers rigid seating in MT4 tool holders, contributing to improved hole accuracy and reduced runout during drilling.
Use cases include drilling large clearance or pass-through holes in fixtures, jigs, and machine frames where a single, sizeable hole is required.
Compared to smaller-diameter options, this bit provides higher material removal rates for large-hole workpieces when paired with appropriate speeds and feeds.
