Kennametal 1785289 Replaceable-tip Drill 14.3-14.5mm Weldon

Product Description

The KENNAMETAL 1785289 is a replaceable-tip drill body designed for precision hole-making in metal cutting applications. It accepts KSEM0563 series inserts at an Insert Seat Size B, allowing the cutting tip to be swapped without replacing the entire drill body. The tool covers a diameter range of 14.3 to 14.5 mm (0.563 to 0.571 inches) and reaches a maximum drill depth of 71.44 mm (2.81 inches), representing a 5xD depth-to-diameter ratio. Through-coolant capability is standard, supplied via 1/8-27 NPT ports at both the shank end and body side. Machinists and CNC operators in production shops install this tool in machining centers and turning centers where consistent, repeatable hole geometry is required.

This drill body is suited for medium-to-high production environments running ferrous and non-ferrous materials where replaceable-tip tooling reduces downtime versus brazed or solid carbide alternatives. The Weldon flat shank with a 19.05 mm (0.75 inch) shank diameter seats securely in standard Weldon-style tool holders, making setup straightforward on horizontal and vertical machining centers. The KSEM series platform is engineered for shops that prioritize insert-index speed and consistent cutting geometry across high-volume runs.

Key Features

• Replaceable-tip design accepts KSEM0563 inserts, Insert Seat Size B - no full-body replacement needed at tip wear

• 5xD depth-to-diameter ratio with a maximum drill depth of 71.44 mm (2.81 inches)
• Weldon flat shank at 19.05 mm diameter for positive anti-rotation engagement in Weldon-style holders
• Overall length of 158.75 mm (6.25 inches) with a flute length of 84.10 mm (3.31 inches)
• Diameter range of 14.3 to 14.5 mm accommodates minor diameter adjustment with compatible insert selection

Compatibility

Compatible with KSEM0563 series replaceable-tip inserts at Insert Seat Size B within the KSEM tooling platform.

Installation Notes

Installation is performed by CNC machinists or toolroom technicians. Power down and lock out the machine spindle before inserting or removing the drill body from the tool holder. Seat the Weldon flat shank fully into the holder and tighten the set screw against the flat to prevent axial pull-out during cutting. Verify coolant line connections at the 1/8-27 NPT ports are sealed and confirm through-coolant flow before initiating a cut cycle.
