Sumitomo 5L00W0S Replaceable-tip Drill 19.51-20.5mm

Product Description

The SUMITOMO 5L00W0S is a replaceable-tip drill body designed for precision metal-cutting operations in production and job-shop environments. Built to the SMD series standard, this drill accepts SMDT-style inserts and features through-coolant capability to manage heat and chip evacuation at depth. The steel body carries a 1-inch whistle notch shank and achieves a maximum drill depth of 4.449 inches at a 5xD depth-to-diameter ratio. It is intended for use by machinists and tooling technicians working on CNC machining centers and drill presses where repeatable bore quality is required.

This drill body accommodates bore diameters ranging from 19.51 mm (0.7681 inches) to 20.5 mm (0.8070 inches) depending on the SMDT insert selected. The 5xD depth ratio makes it well-suited for through-holes and deep-bore applications in steel, cast iron, and similar workpiece materials. The whistle notch shank provides positive drive engagement in compatible SMDH toolholders, reducing the risk of shank pullout under high feed loads common in high-production drilling cycles.

Key Features

• Replaceable SMDT insert tip eliminates the need to replace the entire drill body, reducing tooling cost per hole
• Through-coolant design delivers cutting fluid directly to the cutting zone for improved chip flushing and tool life at depth
• 5xD depth-to-diameter ratio supports maximum drill depth of 4.449 inches in a single pass
• 1-inch whistle notch shank provides positive rotational drive in SMDH-style toolholders
• Steel body construction balances rigidity and weight for stable performance at recommended feed and speed parameters
• Overall length of 7.677 inches with a flute length of 5.427 inches accommodates a range of machine spindle configurations

Compatibility

Designed for use with SMDT-style replaceable-tip inserts and SMDH-series toolholders. Compatible drill diameter range is 19.51 mm to 20.5 mm depending on insert selection.

Installation Notes

Installation and insert changes should be performed by a qualified machinist with the spindle fully stopped and the machine in a locked-out, energy-isolated state per applicable shop safety procedures. Confirm the whistle notch shank is properly seated and secured in the toolholder before initiating a cut. Through-coolant lines should be verified for flow and pressure before running at full feed rates. Follow the insert manufacturer torque recommendations for the SMDT clamping screw when seating a new tip.
