Kennametal 2238558 Replaceable-tip Drill Ksem Series 3xd

Product Description

The KENNAMETAL 2238558 is a replaceable-tip drill body in the KSEM series, designed for high-productivity hole-making in metalworking applications. It accepts KSEM1031 indexable inserts at insert seat size 6, allowing tip changes without removing the body from the spindle. The drill covers a diameter range of 1.0311 to 1.0512 inches (26.19 to 26.70 mm) and reaches a maximum drill depth of 3.09 inches (78.58 mm), corresponding to a 3xD depth-to-diameter ratio. Through-coolant capability is built in via a 0.1575-inch (4.00 mm) coolant hole, supporting chip evacuation and tool life at elevated feed rates. The straight-cylindrical shank measures 31.75 mm in diameter and 3.25 inches in shank length. Overall length is 7.5 inches. This tool body is installed by CNC machinists and toolroom technicians in production turning and machining centers.

The 2238558 drill body is suited for through-hole and blind-hole drilling in steel, cast iron, and similar workpiece materials in both job-shop and production environments. The replaceable-tip design reduces tooling downtime - when insert wear occurs, the seat accepts a fresh KSEM1031 tip without disturbing the qualified shank position in the holder. It is appropriate for horizontal and vertical machining centers equipped with through-spindle coolant. The 3xD depth capacity covers a broad range of structural and mechanical component drilling cycles where a single-pass operation is preferred over peck drilling.

Compatibility

Compatible insert style is KSEM1031 at insert seat size 6. This body is part of the KENNAMETAL KSEM series platform. No additional compatible model numbers or machine-specific fitment data were provided in the product input.

Installation Notes

Installation is performed by a qualified CNC machinist or toolroom technician. Ensure the machine spindle is fully stopped and the tool change mode is engaged before mounting or removing the drill body from the toolholder. Torque the insert screw and toolholder clamping mechanism according to the machine tool and toolholder manufacturer specifications - no torque values specific to this body were provided with this listing. Verify through-coolant passages are unobstructed and coolant pressure is within the machining center manufacturer guidelines before initiating a cut.
