Kennametal 1329706 Replaceable-tip Drill 25-25.5mm

Product Description

The KENNAMETAL 1329706 is a replaceable-tip drill designed for precision hole-making in metal fabrication and machining applications. It accepts KSEM0984 insert tips at an insert seat size 5, allowing the tool body to be reused while only the cutting tip is replaced. The drill covers a diameter range of 25 to 25.5 mm (0.9843 to 1.0039 inches) and reaches a maximum drill depth of 130 mm (5.12 inches), with a depth-to-diameter ratio of 5xD. A through-coolant channel with a 4 mm (0.1575-inch) coolant hole diameter delivers cutting fluid directly to the tip, extending insert life and improving chip evacuation. This tool is installed and operated by machinists and CNC operators in production and job-shop environments.

The 1329706 is suited for drilling operations in ferrous and non-ferrous metals where repeatable accuracy and long tool body life are priorities. Its straight-cylindrical shank measures 25.4 mm in diameter and 76.20 mm (3 inches) in length, making it compatible with standard drill chucks and collet systems used on CNC machining centers, turning centers, and drill presses. The KSEM series platform it belongs to is a modular drilling system that supports multiple insert styles across a range of bore sizes and depth ratios.

Key Features

• Replaceable-tip design with KSEM0984 insert compatibility reduces per-hole tooling cost compared to solid carbide drills
• Diameter range of 25 to 25.5 mm (0.9843 to 1.0039 inches) for flexible bore sizing
• 5xD depth-to-diameter ratio supports drilling to 130 mm (5.12 inches) maximum depth
• Through-coolant delivery via 4 mm coolant hole improves chip flushing and heat management
• Straight-cylindrical shank fits standard CNC toolholders and drill chucks
• Reusable steel tool body with insert seat size 5 for quick tip changes without full tool replacement

Compatibility

Designed for use with KSEM0984 replaceable drill tip inserts at insert seat size 5, part of the KENNAMETAL KSEM modular drilling system. The straight-cylindrical shank is compatible with standard drill chucks and collet-style toolholders sized for a 25.4 mm shank diameter.

Installation Notes

Installation and tool changes should be performed by qualified machinists following the machine tool manufacturer's lockout and spindle-stop procedures before handling the insert or tool body. Confirm insert seating is fully engaged and the locking screw is torqued per the insert manufacturer's guidelines before resuming operation. Through-coolant connections should be verified at the toolholder interface to ensure unobstructed flow to the cutting tip. Refer to applicable shop safety standards and machine tool operating procedures when setting depth stops and feed rates.
