Sumitomo 5L00W1H Replaceable-tip Drill 27.81-28.8mm

Product Description

The SUMITOMO 5L00W1H is a replaceable-tip drill body designed for precision hole-making in metal fabrication and machining applications. It accepts SMDT-style inserts and covers a drill diameter range of 27.81 to 28.80 mm (1.0949 to 1.1339 inches), making it a versatile tool body for through-hole and blind-hole drilling operations. The tool features a 1-1/4 inch whistle notch shank and an overall length of 9.449 inches, with a maximum drill depth of 6.181 inches at a 5xD depth-to-diameter ratio. Through-coolant capability allows high-efficiency chip evacuation and thermal management during extended drilling cycles. This tool is installed and operated by machinists and CNC tooling specialists in production or job-shop environments.

The 5L00W1H belongs to the SUMITOMO SMD series and is suited for drilling operations requiring consistent bore diameter control in the 27.81 to 28.80 mm range. Its replaceable-tip design eliminates the need to replace the entire drill body when the cutting edge wears, reducing tooling cost per hole. The whistle notch shank interfaces with SMDH-style toolholders. It is commonly applied in automotive, aerospace, and general metalworking where repeatable, high-depth drilling is required.

Key Features

• 5xD depth-to-diameter ratio with a maximum drill depth of 6.181 inches
• Through-coolant design for chip evacuation and heat control during deep drilling
• Replaceable SMDT insert tip reduces per-hole tooling cost versus solid drill bodies
• 1-1/4 inch whistle notch shank compatible with SMDH-style toolholders
• Steel body construction in the SMD series platform

Compatibility

The 5L00W1H is compatible with SMDT-style replaceable drill tip inserts and SMDH-style toolholders. It is designed as a drill body within the SUMITOMO SMD series platform.

Installation Notes

Installation and setup should be performed by a qualified machinist familiar with indexable drilling tooling. Ensure the machine spindle and toolholder are fully powered down and locked out before inserting or removing the drill body or replacing the SMDT insert tip. Verify shank seating in the SMDH toolholder and confirm coolant passages are clear and connected before initiating a cutting cycle. Follow the machine tool manufacturer and insert manufacturer guidelines for feed rate and spindle speed selection for the workpiece material.
