Kennametal 4151804 Solid Carbide Jobber Drill 2.60mm

Product Description

The KENNAMETAL 4151804 is a solid carbide jobber-length drill bit engineered for precision hole-making in demanding materials. Built to DIN 6537K specification, it features a 140-degree point angle with a standard point geometry and a multilayer TiAlN coating that extends tool life under high-speed cutting conditions. The 2.60 mm diameter cutting edge and right-hand spiral flute design deliver consistent chip evacuation in short-run and production drilling applications. At 58.00 mm overall length with a 22.00 mm flute length, this drill is suited for machinists and tooling professionals working on tight-tolerance holes in ferrous and non-ferrous materials.

This drill is intended for use in steel, stainless steel, cast iron, aluminum, and other non-ferrous materials. The 5xD flute-to-diameter ratio supports controlled drilling depth up to 17.00 mm, making it appropriate for CNC machining centers, drill presses, and manual milling operations requiring repeatable accuracy. The straight cylindrical shank with a 4 mm shank diameter fits standard collets and chucks without modification. It is a single-piece, solid carbide construction with no brazed joints, suited for shops running moderate to high feed rates.

Key Features

• Solid carbide construction rated as high-performance grade for extended tool life in hard materials
• 140-degree point angle reduces thrust force and improves entry accuracy on flat and curved surfaces
• Multilayer TiAlN coating provides heat resistance and wear protection at elevated cutting speeds
• DIN 6537K specification ensures dimensional consistency and interchangeability with standard toolholding
• Right-hand regular spiral flute with tapered web configuration promotes efficient chip removal
• 5xD flute ratio supports drilling to a maximum depth of 17.00 mm without coolant-through requirement

Compatibility

Designed as an OEM-specification solid carbide jobber drill for use in standard straight-shank collets, drill chucks, and CNC toolholding systems accepting a 4 mm shank diameter. Suited for workpiece materials including steel, stainless steel, cast iron, aluminum, and non-ferrous alloys as noted in the product specifications.

Installation Notes

Installation and use should be performed by a qualified machinist or tooling technician familiar with cutting tool setup and speeds-and-feeds selection. Secure the straight shank firmly in a calibrated collet or drill chuck before operation and verify runout before cutting. Power down the machine and lock out energy sources before inserting or removing the tool. Do not use this drill in impact-type drivers or hand drills, as solid carbide is brittle and will fracture under lateral or shock loading.
