Sumitomo 5L00W1C Replaceable-tip Drill 25.81-26.8mm

Product Description

The SUMITOMO 5L00W1C is a replaceable-tip drill designed for precision hole-making in metalworking and machining applications. Part of the SMD series, it accepts SMDT-style inserts and delivers a drill depth-to-diameter ratio of 3xD, with a maximum drill depth of 3.622 inches. The drill covers a diameter range of 25.81 mm to 26.8 mm (1.0161 to 1.0551 decimal inches) and features a 1-1/4 inch whistle notch shank for secure toolholder engagement. Through-coolant capability supports chip evacuation and thermal management during deep-hole drilling operations. Machinist and CNC operators working in production environments will find this body well-suited to high-feed drilling cycles.

This replaceable-tip drill body is intended for use on CNC machining centers and turning centers equipped with SMDH-style toolholders. The whistle notch shank provides positive axial retention in compatible toolholders. With an overall length of 6.89 inches and a flute length of 4.517 inches, the 5L00W1C is configured for intermediate-depth drilling passes. It is appropriate for job shop and production-floor use where repeatable bore diameter consistency and fast tip changeover are priorities.

Key Features

• Diameter range of 25.81 mm to 26.8 mm (1.0161 to 1.0551 inches) using SMDT replaceable inserts
• 3xD depth-to-diameter ratio with a maximum drill depth of 3.622 inches
• Through-coolant design for active chip flushing and heat reduction
• 1-1/4 inch whistle notch shank for positive axial retention in SMDH toolholders
• Steel body construction for durability in high-cycle machining environments
• Replaceable-tip design reduces tooling cost by allowing insert swap without replacing the body

Compatibility

Compatible with SMDT-style replaceable drill inserts and SMDH-style toolholders. Part of the SMD series drill body platform.

Installation Notes

Installation should be performed by a qualified machinist or tooling setup technician. Secure the whistle notch shank fully into the SMDH toolholder before operation and confirm proper torque to the toolholder manufacturer specification. Verify through-coolant lines are connected and flow is confirmed before starting a drilling cycle. Always inspect the SMDT insert seating and condition before each run.
