Sumitomo 5L00W0H Replaceable-tip Drill 16.51-17.50mm Weldon

Product Description

The SUMITOMO 5L00W0H is a replaceable-tip drill body engineered for precision hole-making in metal cutting applications. It accepts SMDT-style insert tips and features a 3/4-inch Weldon flat shank for positive, non-slip retention in compatible toolholders. The drill body covers a diameter range of 16.51 to 17.50 mm (0.650 to 0.689 inches) and delivers a maximum drill depth of 3.78 inches, supporting a 3xD depth-to-diameter ratio. Through-coolant capability directs cutting fluid directly to the cutting zone, extending insert life and aiding chip evacuation in deep-hole operations. This body is part of the SMD series and is intended for use by machinists and CNC operators in production environments.

The 5L00W0H is suited for drilling operations in ferrous and non-ferrous metals where consistent hole geometry and high feed rates are required. The Weldon flat shank interfaces with SMDH-style toolholders. With an overall length of 6.693 inches, a flute length of 4.693 inches, and a shank length of 2.000 inches, this body fits standard CNC machining center setups where controlled depth and rigidity are critical. The replaceable-tip design reduces downtime by allowing insert changes without removing the body from the holder.

Key Features

• Accepts SMDT-style replaceable insert tips for quick cutting-edge changes
• Through-coolant design improves chip flushing and extends tool life in deep holes
• 3/4-inch Weldon flat shank provides positive drive and minimal runout
• 3xD depth-to-diameter ratio supports maximum drill depth of 3.78 inches
• Compatible with SMDH-series toolholders for rigid, repeatable setups
• Steel body construction balances rigidity and weight in high-feed drilling

Compatibility

Designed for use with SMDT-style insert tips and SMDH-series toolholders within the SUMITOMO SMD replaceable-tip drill system. Requires a toolholder with a 3/4-inch Weldon flat shank bore.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before mounting or removing the drill body. Seat the Weldon flat shank fully into the toolholder and torque the set screw per the toolholder manufacturer specifications. Verify through-coolant passages are clear and that coolant pressure is adequate before beginning the drilling cycle.
