Kennametal 1503488 Replaceable-tip Drill 17.46-17.96mm

Product Description

The KENNAMETAL 1503488 is a replaceable-tip drill body designed for precision hole-making in metalworking and machining applications. The body accepts KSEM0688 series inserts at an insert seat size of 1, enabling quick tip changes without removing the holder from the spindle. It covers a drill diameter range of 17.46 to 17.96 mm (0.6874 to 0.7071 inches) with a maximum drill depth of 90 mm (3.54 inches), rated at a 5xD depth-to-diameter ratio. The straight-cylindrical shank measures 19.05 mm in diameter and 50.80 mm in length. Through-coolant capability is built in, with a coolant hole diameter of 3.50 mm (0.1378 inches) to support chip evacuation and tool life at elevated feed rates. This body is part of the KSEM series and is intended for use by machinist and CNC tooling professionals.

The 1503488 is suited for CNC machining centers and manual machine tools where consistent, repeatable hole quality is required in ferrous and non-ferrous metals. The replaceable-tip design reduces tooling downtime by allowing insert swaps at the machine without full tool replacement. The 5xD depth ratio makes it appropriate for medium-depth holes in production environments such as automotive, aerospace, and general job-shop machining. Through-coolant delivery supports higher cutting speeds and extends insert service life in demanding materials.

Installation Notes

Installation and insert changes should be performed by a qualified machinist following the machine tool manufacturer lockout and energy-isolation procedures before any tooling adjustments are made. Verify that the straight-cylindrical shank is properly seated and clamped to the specified holder torque per your toolholder manufacturer guidelines before running. Through-coolant passages should be inspected and cleared of debris before mounting. Confirm insert seat is clean and undamaged before seating the KSEM0688 tip to ensure accurate tip positioning and prevent premature insert failure.
