Kennametal 4151792 Jobber Drill 1.90mm Solid Carbide

Product Description

The KENNAMETAL 4151792 is a solid carbide jobber-length drill designed for high-performance drilling in demanding industrial applications. Built to DIN 6537K standards, it features a 140-degree point angle and a multilayer TiAlN coating that extends tool life in abrasive and high-temperature cutting environments. The drill measures 1.90 mm in diameter with an overall length of 58.00 mm (2.2835 inches) and a flute length of 12.00 mm (0.4724 inches). The right-hand, regular spiral flute geometry promotes efficient chip evacuation. This drill is installed by machinists and tool-room professionals working with precision drilling operations on ferrous and non-ferrous workpieces.

The 4151792 is suited for drilling steel, stainless steel, cast iron, aluminum, and other non-ferrous materials. Its 5xD flute-to-diameter ratio and tapered web configuration make it appropriate for short-hole drilling cycles in production and maintenance machining environments. The straight cylindrical shank with a 4 mm shank diameter (0.5000 inches) fits standard collet chucks and drill chucks across CNC machining centers, drill presses, and manual machines. Maximum drilling depth is rated at 9.00 mm (0.3543 inches).

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• Multilayer TiAlN coating extends tool life in high-heat cutting conditions
• 140-degree point angle reduces thrust force and improves centering on entry
• DIN 6537K specification ensures dimensional consistency and interchangeability
• Right-hand regular spiral flutes with tapered web for reliable chip evacuation
• Straight cylindrical shank compatible with standard collet and drill chuck toolholders

Compatibility

Designed as an OEM-style replacement and general-purpose jobber drill for machine tool setups requiring a 1.90 mm solid carbide drill conforming to DIN 6537K. Compatible with steel, stainless steel, cast iron, aluminum, and non-ferrous workpiece materials as specified by the manufacturer.

Installation Notes

Installation and use of this drill is performed by qualified machinists or toolroom technicians. Ensure the machine spindle and chuck or collet are fully stopped and the machine is locked out before changing tooling. Verify shank seating and runout with a dial indicator before beginning production drilling. Do not exceed the rated maximum drilling depth of 9.00 mm without repositioning or pecking to clear chips.
