Ingersoll Cutting Tools 3240721 Indexable Insert Drill

Product Description

The INGERSOLL CUTTING TOOLS 3240721 is an indexable insert drill from the Quad Drill series, designed for general-purpose hole-making in metal cutting applications. It accepts two replaceable inserts and delivers a maximum drill depth of 2.81 inches at a 3xD depth-to-diameter ratio. The drill body measures 3.86 inches in total body length with a 1.25-inch straight-cylindrical shank for secure, concentric clamping in standard chucks and holders. Coolant-through capability channels fluid directly to the cutting zone, extending insert life and improving chip evacuation. This tool is installed and operated by machinists and CNC toolroom technicians working with drill presses, machining centers, and lathes.

This indexable insert drill is suited for general-purpose drilling operations in production and job-shop environments. The 3xD ratio makes it well matched to through-hole and blind-hole work where moderate depth-to-diameter demands apply. The straight-cylindrical shank with a 1-1/4 inch modular connection size fits a wide range of standard toolholding systems. Right-hand cutting direction is standard for conventional spindle rotation. Compatible insert style is SPLT 07T308N-PH, which can be sourced separately when replacement is needed.

Compatibility

Compatible insert style is SPLT 07T308N-PH. The drill uses a straight-cylindrical shank with a 1-1/4 inch modular connection size and is compatible with standard toolholding systems accepting that shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before inserting or removing the drill body from any toolholder. Torque insert screws using the appropriate Torx or hex key as specified by the insert supplier - do not overtighten. Verify runout and axial alignment after mounting before initiating a cut, and confirm coolant-through circuits are open and functioning before starting the drilling cycle.
