Kennametal 1505128 Replaceable-tip Drill Weldon Flat

Product Description

The KENNAMETAL 1505128 is a replaceable-tip drill body designed for precision hole-making in metal cutting applications. It accepts KSEM1188 inserts at an insert seat size 8, delivering a drilling diameter range of 30.16 to 30.66 mm (1.1874 to 1.2071 inches) with a maximum drill depth of 96 mm (3.78 inches). The body features a Weldon flat shank at 31.75 mm diameter and through-coolant capability via NPT-threaded coolant ports, supporting high-pressure coolant delivery directly to the cutting zone. Part of the KSEM series, this drill body is installed by machinists and toolroom technicians in CNC machining centers and drill presses running production or job-shop work.

The 1505128 is suited for moderate-to-deep hole drilling at a 3xD depth-to-diameter ratio, fitting applications in general manufacturing, aerospace component machining, die and mold work, and similar metal-removal environments. The Weldon flat shank provides positive rotational drive and secure tool holding in compatible chucks and holders. Through-coolant delivery supports chip evacuation and tool life in ferrous and non-ferrous workpiece materials. This body is intended for use in machines capable of delivering coolant under pressure through the spindle or via body-side coolant ports.

Key Features

• Drilling diameter range: 30.16 to 30.66 mm (1.1874 to 1.2071 inches) using KSEM1188 inserts
• Maximum drill depth: 96 mm (3.78 inches) at a 3xD depth-to-diameter ratio
• Weldon flat shank at 31.75 mm for positive rotational engagement and secure chuck retention
• Through-coolant design with body-side 1/8-27 NPT and shank-end 1/4-18 NPT coolant ports
• Overall length of 234.95 mm (9.25 inches) with a flute length of 133.48 mm (5.255 inches)
• Replaceable-tip system reduces tooling cost by replacing only the insert, not the body

Compatibility

Compatible with KSEM1188 series inserts at insert seat size 8, part of the KENNAMETAL KSEM replaceable-tip drill system. Intended for use in machine spindles and tool holders accepting a 31.75 mm Weldon flat shank.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. De-energize the machine and lock out the spindle before mounting or removing the drill body or replacing inserts. Verify that the tool holder torque and coolant pressure settings conform to the machine tool manufacturer specifications and applicable shop safety procedures. Do not exceed the maximum recommended drill depth or feed rates specified in the KSEM series application guidelines.
