Sumitomo 5L00W0L Replaceable-tip Drill 17.51-18.5mm

Product Description

The SUMITOMO 5L00W0L is a replaceable-tip drill body designed for precision hole-making in metal and industrial workpiece applications. Built on the SMD series platform, this drill accepts SMDT-style indexable inserts, allowing the cutting tip to be swapped without replacing the entire tool body. The shank measures 3/4 inch in diameter with a whistle notch configuration for secure toolholder engagement. Maximum drill depth reaches 4.015 inches, and the overall length is 6.89 inches. Through-coolant capability channels cutting fluid directly to the cutting zone, reducing heat and extending insert life during deep-hole operations.

This drill body is suited for production drilling operations in machining centers and CNC lathes where repeatable hole quality and fast insert changes are priorities. The 5xD depth-to-diameter ratio makes it appropriate for moderate-depth holes in a range of workpiece materials. The whistle notch shank is compatible with SMDH-style toolholders. The drill is configured for a cutting diameter range of 17.51 mm to 18.5 mm (0.6894 to 0.7283 inches), giving the operator flexibility to dial in the exact hole size required by pairing with the appropriate SMDT insert.

Key Features

• Replaceable SMDT insert tip — cutting edge can be indexed or replaced without removing the drill body from the machine
• Through-coolant design delivers fluid directly to the cutting zone for improved chip evacuation and thermal control
• Whistle notch shank (3/4 inch diameter) provides positive drive and resists rotation in SMDH-style toolholders
• 5xD drill depth-to-diameter ratio supports hole depths up to 4.015 inches
• SMD series body in steel construction for rigidity during high-feed drilling operations
• Flute and body length of 4.89 inches accommodates full chip flow through the cutting depth range

Compatibility

Designed for use with SMDT-style indexable drill inserts and SMDH-style toolholders within the SMD series system. Accepts inserts sized for a cutting diameter range of 17.51 mm to 18.5 mm.

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 tool changer is in a safe state before mounting or removing the drill body. Torque the whistle notch retention screw to the toolholder specification supplied by the holder manufacturer — do not rely on hand-tight engagement. Verify through-coolant passages are clear and that the machine coolant pressure is compatible with the tool before beginning a cutting cycle.
