Sumitomo 5L00W19 Replaceable-tip Drill 24.81-25.8mm

Product Description

The SUMITOMO 5L00W19 is a replaceable-tip drill body designed for precision hole-making in metal cutting applications. Built on the SMD series platform, it accepts SMDT-style indexable inserts, allowing the cutting tip to be swapped without removing the tool body from the machine. The 5L00W19 covers a diameter range of 24.81 mm to 25.8 mm (0.9768 to 1.0157 inches) and reaches a maximum drill depth of 3.465 inches, placing it in the 3xD depth-to-diameter ratio category. Through-coolant delivery is standard, directing fluid directly to the cutting zone for chip evacuation and heat control. The steel body shank measures 1.25 inches in diameter with a whistle notch profile for positive retention in the toolholder.

This drill body is suited for CNC machining centers and turning centers in production environments where consistent hole quality and fast insert changes are priorities. The through-coolant feature makes it well-matched for drilling steel, cast iron, and similar ferrous materials where chip packing is a concern. The SMDH toolholder style is the specified mating holder for this body. Machinists and tooling specialists in job shops, automotive production, and general manufacturing will find this drill appropriate for medium-volume hole-making operations requiring repeatable diameter control within the 24.81 to 25.8 mm range.

Key Features

• Replaceable SMDT insert tip eliminates the need to regrind or replace the full drill body
• Through-coolant design channels fluid directly to the cutting edge for improved chip evacuation
• 3xD depth-to-diameter ratio with a maximum drill depth of 3.465 inches
• Whistle notch shank at 1.25 inches diameter provides positive anti-rotation seating in the toolholder
• SMD series body pairs with SMDH-style toolholders for a matched system setup
• Overall length of 6.693 inches with a flute and body length of 4.318 inches

Compatibility

Designed for use with SMDT-style replaceable inserts and SMDH-series toolholders. This body is part of the SUMITOMO SMD replaceable-tip drill system and is not compatible with solid carbide or brazed-tip drill holders outside that system.

Installation Notes

Installation and tooling changes should be performed by a qualified machinist or tooling technician with the machine in a fully stopped and locked-out state. Confirm the SMDH toolholder is properly torqued to the spindle before operation and that the whistle notch is fully seated and secured in the holder bore. Verify through-coolant lines are clear and delivering adequate flow before beginning a drilling cycle. Follow the machine tool manufacturer and insert manufacturer recommendations for speeds, feeds, and insert torque values specific to the SMDT insert being used.
