Kennametal 1505130 Replaceable-tip Drill 31.75-32mm Weldon

Product Description

The KENNAMETAL 1505130 is a replaceable-tip drill body designed for high-productivity hole-making in metal cutting applications. It accepts KSEM1250 insert tips at an insert seat size 8 and belongs to the KSEM series platform. The drill body features a Weldon Flat shank measuring 31.75 mm in diameter, an overall length of 9.25 inches (234.95 mm), and a flute length of 5.26 inches (133.48 mm). Through-coolant delivery is supported via NPT-threaded coolant ports, with a body side coolant hole thread size of 1/8-27 and a shank end coolant hole thread size of 1/4-18. This tool is installed and operated by machinists and CNC tooling specialists working with drilling centers and machining centers.

The 1505130 is suited for drilling operations requiring a 3xD depth-to-diameter ratio, with a maximum drill depth of 3.78 inches (96 mm). The drill diameter range spans 31.75 mm (1.2500 inches) to 32.00 mm (1.2598 inches), making it applicable in precision-tolerance boring and hole-finishing operations. Typical use cases include production machining of steel, cast iron, and similar ferrous workpiece materials in both job shop and high-volume manufacturing environments. The replaceable-tip design reduces tooling cost by allowing insert exchange without replacing the full drill body.

Key Features

• Replaceable KSEM1250 insert tip at seat size 8 allows quick tip changes without full body replacement
• Through-coolant capability with NPT-threaded ports at both body side (1/8-27) and shank end (1/4-18) for effective chip evacuation and heat control
• Weldon Flat shank at 31.75 mm diameter provides positive rotational drive and secure toolholder retention
• 3xD depth-to-diameter ratio with 96 mm maximum drill depth suits a wide range of standard through-hole and blind-hole applications
• Drill diameter range of 31.75 to 32.00 mm accommodates close-tolerance hole requirements
• Overall length of 9.25 inches (234.95 mm) with a flute length of 5.26 inches (133.48 mm) for balanced reach and rigidity

Compatibility

Compatible with KSEM1250 series replaceable drill tip inserts at insert seat size 8. Part of the KENNAMETAL KSEM platform. Verify toolholder compatibility with the 31.75 mm Weldon Flat shank specification before installation.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. The machine spindle must be fully stopped and the machine locked out before mounting or removing the drill body or changing insert tips. Use the appropriate Weldon Flat toolholder sized for 31.75 mm shank diameter and confirm that the coolant supply lines are connected to the correct NPT-threaded ports before initiating through-coolant flow. Do not exceed the rated maximum drill depth of 96 mm for this tool body.
