Kennametal 1606885 Replaceable-tip Drill 19.46-19.96mm

Product Description

The KENNAMETAL 1606885 is a replaceable-tip drill body from the KSEM series, designed for high-productivity hole-making in metal cutting applications. The drill accepts KSEM0766 insert tips at an insert seat size 2, allowing fast tip changes without removing the body from the spindle. The overall length is 209.55 mm (8.25 inches), and the drill delivers a 5xD depth-to-diameter ratio with a maximum drill depth of 100.08 mm (3.94 inches). Through-coolant delivery via 3.50 mm coolant holes keeps cutting edges cool and clears chips effectively at elevated feed and speed rates. Licensed machinists and CNC operators in production machining environments are the primary users of this tool.

This drill body is suited for use in CNC machining centers and turning centers where consistent, repeatable hole quality is required across medium-to-high volume production runs. The straight-cylindrical shank measures 25.40 mm in diameter and 76.20 mm in length, fitting standard ER and hydraulic chuck toolholders of the appropriate bore. The 5xD reach makes it appropriate for deeper bore applications in structural steel, cast iron, aluminum alloy, and similar machinable materials where shorter drills cannot reach.

Key Features

• Replaceable KSEM0766 insert tips allow rapid tip changes without disturbing setup
• Through-coolant delivery via 3.50 mm internal coolant holes for chip evacuation and thermal control
• 5xD depth-to-diameter ratio supports drilling depths up to 100.08 mm
• Straight-cylindrical shank (25.40 mm dia, 76.20 mm length) compatible with standard chuck toolholders
• Insert seat size 2 for secure tip retention under high thrust and torque loads
• Flute length of 129.29 mm (5.09 inches) ensures adequate chip clearance over full depth of cut

Compatibility

Compatible with KSEM0766 series replaceable insert tips at insert seat size 2. Part of the KSEM series drill body platform by KENNAMETAL.

Installation Notes

Installation and tool changes should be performed by qualified machinists or CNC toolroom personnel with the machine in an e-stop or fully powered-down state. Verify spindle bore and toolholder specifications match the 25.40 mm straight-cylindrical shank before mounting. Ensure coolant ports in the toolholder are aligned and unobstructed to maintain through-coolant flow. Do not exceed the insert manufacturer's recommended cutting parameters for the selected KSEM0766 tip grade.
