Hertel 4006133 Indexable Insert Drill 2-1/4 in 2xd

Product Description

The HERTEL 4006133 is a 2-1/4 inch diameter indexable insert drill designed for deep-hole drilling applications in metalworking and machining operations. Built with a straight cylindrical shank measuring 1.5 inches in diameter, this drill accepts two replaceable HPMT186812-GP inserts, allowing cutting edges to be swapped without replacing the entire tool body. Maximum drill depth reaches 4.5 inches at a 2xD depth-to-diameter ratio. The flute length measures 4.815 inches and the overall body length is 9.075 inches. Coolant-through capability is included, with a 1/4 inch threaded coolant hole at the shank end. The tool body is constructed of steel and cuts in the right-hand direction. Installed by machinists and CNC operators in production and job-shop environments.

This indexable insert drill is suited for use in CNC machining centers and manual boring mills where large-diameter holes are required in a single pass. The 2xD ratio makes it appropriate for through-holes and blind holes in steel, cast iron, and similar ferrous workpiece materials. The straight-cylindrical shank seats directly into tool holders with a matching 1.5 inch bore. Coolant-through delivery helps manage chip evacuation and heat at the cutting zone, which is critical at this diameter and depth range.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Confirm the machine spindle and tool holder bore match the 1.5 inch shank diameter before mounting. Ensure the machine is fully powered down and the spindle is locked before inserting or removing the tool. When indexing or replacing inserts, use the correct torx or hex key specified by the insert manufacturer and do not exceed recommended insert seating force.
