Kennametal 1505191 Replaceable-tip Drill Ksem Series

Product Description

The KENNAMETAL 1505191 is a replaceable-tip drill body engineered for precision hole-making in metalworking and machining applications. It accepts KSEM1125 series inserts at seat size 7, allowing tip replacement without discarding the body. The drill covers a diameter range of 28.58 to 29.08 mm (1.1252 to 1.1449 inches) with a maximum drill depth of 150 mm (5.91 inches). Overall length is 288.93 mm (11.37 inches). The 31.75 mm Weldon Flat shank provides positive drive in compatible toolholders, and through-coolant capability supports chip evacuation and tool life at depth. Licensed machinists and CNC operators install this tool in production and job-shop environments.

This drill body is suited for 5xD depth-to-diameter ratio applications in ferrous and non-ferrous materials where repeatable, close-tolerance bores are required. The KSEM series design is used in horizontal and vertical machining centers running high-feed, high-volume drilling cycles. The replaceable-tip format reduces per-hole tooling cost compared to solid carbide drills at this diameter range. Through-coolant delivery via body-side and shank-end ports keeps the cutting zone clear during deep-hole passes.

Key Features

• Accepts KSEM1125 replaceable inserts at seat size 7 for fast tip changes without body replacement
• Through-coolant capable with body-side NPT 1/8-27 and shank-end NPT 1/4-18 coolant ports
• Weldon Flat shank (31.75 mm) provides positive rotational drive and secure clamping in side-lock holders
• 5xD drill depth ratio supports maximum drill depth of 150 mm (5.91 inches)
• Flute length of 185.42 mm (7.30 inches) allows chip flow through deep-hole passes
• KSEM series platform allows shared insert inventory across multiple body sizes

Compatibility

Designed for use with KSEM1125 series replaceable drill tips at insert seat size 7. Compatible with Weldon Flat toolholders sized for a 31.75 mm shank diameter. Part of the KENNAMETAL KSEM series platform.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the spindle before seating or removing the replaceable tip. Use the appropriate torque wrench and KENNAMETAL-specified clamping hardware for the KSEM insert seat - do not overtighten with general-purpose tools. Verify coolant port connections and through-coolant pressure compatibility with the machine spindle before initiating a drilling cycle.
