Sumitomo 2A00W2N Indexable Insert Drill 15/16 in 4xd

Product Description

The SUMITOMO 2A00W2N is an indexable insert drill from the SumiDrill series, designed for general-purpose drilling in metal fabrication, machining, and production environments. It accepts two WDXT-style inserts and produces a maximum drill diameter of 15/16 inches (0.9370 inches decimal). Maximum drill depth reaches 3.868 inches, placing this tool in the 4xD depth-to-diameter ratio class. The shank is a 1-1/4 inch whistle notch design, providing positive drive engagement in standard drill holders. A coolant-through design with a 1/4-18 NPT coolant hole thread keeps cutting edges clear and controls heat at the tip. This tool is installed by CNC machinists and tool-and-die professionals on machining centers and lathes equipped for indexable tooling.

The 2A00W2N is suited for drilling operations in ferrous and non-ferrous materials where hole depth falls in the 3.0 to 4.0 inch range. Its right-hand cutting direction is standard for conventional spindle rotation. The whistle notch shank seats securely in standard boring bar and drill holders sized for 1-1/4 inch shanks. The coolant-through capability makes it appropriate for deep-hole applications where chip evacuation and thermal management are priorities in production or job-shop settings.

Installation Notes

Installation should be performed by a qualified machinist with the spindle fully stopped and the machine locked out per facility lockout/tagout procedures. Confirm the holder bore and drive slot are sized for a 1-1/4 inch whistle notch shank before mounting. Torque the clamping screw to the holder manufacturer's specification. Verify coolant supply line connection at the 1/4-18 NPT port before running the tool, and confirm insert seating and screw torque on both inserts per the SUMITOMO insert clamping specification.
