Kennametal 1785245 Replaceable-tip Drill Weldon Flat Shank

Product Description

The KENNAMETAL 1785245 is a replaceable-tip drill body designed for precision hole-making in metalworking applications. It accepts KSEM0500 series inserts at an insert seat size C, covering a drill diameter range of 12.7 to 13.2 mm (0.500 to 0.520 inches). Maximum drill depth is 38.1 mm (1.500 inches), representing a 3xD depth-to-diameter ratio. The body measures 123.83 mm (4.875 inches) in overall length with a 19.05 mm Weldon Flat shank. Through-coolant capability is built in via 1/8-27 NPT coolant ports at both the shank end and body side, keeping cutting temperatures controlled during extended production runs.

This drill body is suited for industrial CNC machining centers and milling machines used in manufacturing, toolroom, and production environments. The replaceable-tip design reduces tooling cost per hole by allowing insert swap-out without replacing the full body. It is primarily installed by machinists and CNC programmers working in ferrous and non-ferrous material applications. The Weldon Flat shank seats securely in compatible toolholders to resist pullout under high feed conditions.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the tool is de-energized before changing inserts or mounting the drill body. Seat the Weldon Flat shank fully in the toolholder and tighten the clamping screw to the toolholder manufacturer specifications before operation. Verify coolant line connections at the 1/8-27 NPT ports are leak-free before engaging through-coolant flow.
