Sumitomo 5L00W0K Replaceable-tip Drill 17.51-18.5mm

Product Description

The SUMITOMO 5L00W0K is a replaceable-tip drill designed for precision hole-making in metal fabrication and machining applications. It accepts SMDT-style insert tips and supports a drill diameter range of 17.51 mm to 18.5 mm (0.6894 to 0.7283 inches), giving machinists flexibility across close-tolerance bore sizes. The tool features a 3/4 inch whistle notch shank, an overall length of 8.898 inches, and through-coolant capability that channels cutting fluid directly to the tip for improved chip evacuation and tool life. The steel body is built for use in CNC turning centers and machining centers where rigidity and repeatability are critical.

This drill is suited for production drilling in shops handling steel, cast iron, and similar ferrous workpieces. With a maximum drill depth of 6.299 inches and an 8xD depth-to-diameter ratio, it handles deep-hole applications that exceed the reach of standard drills. The through-coolant design makes it particularly effective in high-speed or high-feed operations where heat buildup at the cutting zone would otherwise limit performance. Machinists running SMD-series tooling programs will find this body compatible with the SMDH toolholder style.

Key Features

• Replaceable SMDT insert tip eliminates regrinding and reduces downtime
• Drill diameter range: 17.51 mm to 18.5 mm (0.6894 to 0.7283 inches)
• Through-coolant construction channels fluid directly to the cutting edge
• 8xD depth-to-diameter ratio supports deep-hole drilling up to 6.299 inches
• 3/4 inch whistle notch shank for secure machine-side retention
• Steel body engineered for SMD series compatibility with SMDH toolholders

Compatibility

Designed for use with SMDT-style replaceable inserts and SMDH-style toolholders within the SMD series platform. Confirm insert grade and geometry selection against workpiece material before assembly.

Installation Notes

Installation and setup should be performed by a qualified machinist familiar with rotating tool assemblies and CNC machine operation. Power down and lock out the machine spindle before inserting or removing the tool body or changing insert tips. Verify shank seating and coolant port alignment in the toolholder before running at operating speed. Follow the machine tool manufacturer torque specifications for the toolholder clamping mechanism and confirm runout with a dial indicator before cutting.
