Kennametal 1198588 Solid Carbide Die Drill Bit 0.2047 in

Product Description

The KENNAMETAL 1198588 is a solid carbide straight-flute die drill bit designed for precision hole-making in cast iron and non-ferrous metals. Part of the Series B411 line, it features a 130-degree split point and web-thinned geometry that reduces thrust and improves centering at entry. The bright (uncoated) finish suits applications where coating buildup or contamination is a concern. Coolant-through capability via a round coolant hole allows internal flush to clear chips and manage heat at the cutting zone. With a 0.2047-inch (5.20 mm) cutting diameter and a right-hand cutting direction, this bit is built for repeatable, tight-tolerance production drilling in die and mold work environments.

This drill bit is suited for use in CNC machining centers, drill presses, and die-making operations targeting cast iron and non-ferrous metal workpieces. The straight-flute design is preferred in die drilling applications where chip control and hole straightness are critical. The DIN 6537L specification aligns it with standard tooling systems used in industrial and mold-shop environments. Machinists, tool-and-die makers, and CNC programmers working with high-precision fixture or die components will find the tight diameter tolerance and split-point geometry well suited to their workflow.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• 130-degree split point with web-thinned geometry reduces entry thrust and improves self-centering
• Straight-flute design optimized for die drilling in cast iron and non-ferrous metals
• Internal coolant-through capability with round coolant hole for chip evacuation and heat management
• Bright finish — no coating — minimizes risk of edge buildup in sensitive applications
• Meets DIN 6537L specification for compatibility with standard toolholding systems

Compatibility

Designed for use with cast iron and non-ferrous metal workpieces as stated by the manufacturer. Intended for toolholding systems accepting a 6.00 mm (approximately 0.236 inches) shank diameter, per DIN 6537L specification. No specific machine model compatibility was provided in the product data.

Installation Notes

Installation and use should be performed by qualified machinists or tool-and-die professionals familiar with carbide tooling. Before mounting, ensure the spindle and toolholder are clean and within specified runout tolerances, as carbide is brittle and sensitive to lateral loading. Verify coolant-through pressure and flow are appropriate for the diameter before engaging the workpiece. Do not exceed the maximum drilling depth of 1.38 inches (35.00 mm) per the manufacturer specification.
