Sumitomo 5L00W0W Replaceable-tip Drill 20.51-21.5mm Whistle Notch

Product Description

The SUMITOMO 5L00W0W is a replaceable-tip drill body designed for precision hole-making in metal cutting applications. Built from steel, this drill accepts SMDT-style inserts and covers a diameter range of 20.51 mm to 21.5 mm (0.8074 to 0.8465 inches). The maximum drill depth is 2.953 inches, achieved through a 3xD depth-to-diameter ratio. The 1-inch whistle notch shank provides secure seating in compatible SMDH-style toolholders. Through-coolant capability keeps cutting temperatures under control during high-feed drilling operations. Licensed machinists and CNC operators handling production drilling work are the primary users of this tool body.

This drill body is suited for CNC machining centers and turning centers where indexable replaceable-tip tooling is preferred over solid carbide drills. The through-coolant design supports uninterrupted chip evacuation and extended insert life in ferrous and non-ferrous materials. The SMD series platform allows quick insert changes without removing the body from the machine, making it practical for high-volume production environments. The whistle notch shank interfaces with SMDH-style holders for rigid, repeatable tool positioning.

Key Features

• Accepts SMDT-style replaceable-tip inserts for fast, on-machine indexing
• Diameter range of 20.51 mm to 21.5 mm suits a variety of bore size requirements
• Through-coolant design promotes chip evacuation and insert life in continuous drilling
• 1-inch whistle notch shank for secure clamping in SMDH-style toolholders
• 3xD depth-to-diameter ratio supports maximum drill depth of 2.953 inches
• Steel body construction for durability in production machining environments

Compatibility

Designed for use with SMDT-style replaceable-tip inserts and SMDH-style toolholders within the SMD series platform. Compatible toolholder style is SMDH. Specific insert and holder part numbers should be confirmed with SUMITOMO tooling documentation before ordering.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the machine is locked out before mounting or removing the tool body. Seat the whistle notch shank fully into the SMDH holder and torque the clamping screw to the value specified in the SUMITOMO toolholder documentation. Verify coolant passages are clear and coolant pressure is set per the machine and tooling manufacturer guidelines before initiating a cutting cycle.
