Sumitomo 5L00W18 Replaceable-tip Drill 24.81-25.8mm

Product Description

The SUMITOMO 5L00W18 is a replaceable-tip drill body designed for precision hole-making in metal cutting applications. Built on the SMD series platform, this drill accepts SMDT-style inserts and delivers a 5xD depth-to-diameter ratio, allowing a maximum drill depth of 5.512 inches. The 1-1/4 inch whistle notch shank provides secure, positive engagement in compatible SMDH-style toolholders. Through-coolant capability channels fluid directly to the cutting zone, extending insert life and improving chip evacuation in deep-hole operations. The steel body measures 8.858 inches overall length with a flute length of 6.483 inches. This tool is installed by machinists and CNC operators working in production drilling environments.

The 5L00W18 covers a drill diameter range of 24.81 mm to 25.80 mm (0.9768 to 1.0157 inches decimal), making it suitable for applications requiring precise, repeatable bore sizes in that range. It is intended for use in CNC machining centers and milling machines equipped with SMDH-compatible toolholders. The 5xD depth ratio makes it well suited for medium-depth drilling operations in steel, cast iron, and similar ferrous workpiece materials where replaceable-tip tooling reduces downtime compared to brazed or solid-carbide alternatives.

Key Features

• Replaceable SMDT insert tips eliminate the need to replace the full drill body on edge wear
• Through-coolant design channels fluid directly to the cutting zone for improved chip evacuation and insert life
• 5xD depth-to-diameter ratio supports maximum drill depth of 5.512 inches
• 1-1/4 inch whistle notch shank provides positive drive engagement in SMDH toolholders
• Steel body construction rated for production-volume drilling cycles
• Diameter range of 24.81 mm to 25.80 mm accommodates slight insert-size variation within the SMD series

Compatibility

Designed for use with SMDT-style replaceable-tip inserts and SMDH-series toolholders. Verify toolholder bore and coolant port alignment before installation.

Installation Notes

Installation and setup should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the machine is in a safe, locked-out state before mounting or dismounting the drill body. Confirm the toolholder shank bore is sized for a 1-1/4 inch whistle notch fit and that the coolant-through circuit is active and unobstructed before beginning a cut. Follow the insert manufacturer torque guidelines when seating SMDT inserts into the drill body pockets.
