Kennametal 4150198 Drill Bit Size 19 Solid Carbide 140 Deg

Product Description

The KENNAMETAL 4150198 is a solid carbide screw machine length drill bit designed for precision drilling in demanding production environments. Built to DIN 6537K standards, it features a 140-degree point angle for aggressive penetration and reduced thrust, and a multilayer TiAlN coating at the tip to extend tool life in abrasive and high-temperature applications. At 0.1660 inches in diameter (wire size 19) with an overall length of 2.5984 inches, this stub-length drill is engineered for rigidity and accuracy in short-reach drilling setups. It is intended for use by machinists, toolroom technicians, and CNC operators working with precision metalworking equipment.

This drill bit is suited for use in screw machine operations, CNC machining centers, and drill press applications where a compact, rigid tool is required. The stub length reduces deflection and improves hole location accuracy compared to jobber-length drills. The 2-flute regular spiral design promotes efficient chip evacuation in a range of workpiece materials. It is a strong fit for high-volume production drilling in metalworking shops running tight tolerances.

Key Features

• Solid carbide construction for maximum rigidity and wear resistance
• 140-degree standard point angle reduces thrust and improves penetration
• TiAlN multilayer coating at the tip extends tool life in high-heat conditions
• Stub (screw machine) length provides superior rigidity and minimizes deflection
• 2-flute regular spiral design supports efficient chip evacuation
• Straight cylindrical shank with 0.2362-inch diameter for standard chuck compatibility
• Meets DIN 6537K specification for consistent dimensional accuracy

Compatibility

Designed for use in standard drill chucks and collets accepting a 0.2362-inch straight cylindrical shank, compatible with CNC machining centers, screw machines, and drill presses requiring a wire size 19 screw machine length drill bit.

Installation Notes

Installation and tool changes should be performed by qualified machinists or toolroom technicians with the spindle fully stopped and the machine de-energized or in a safe lockout state. Ensure the chuck or collet is clean and the shank is fully seated before tightening. Inspect the cutting edges and coating condition before each use, as solid carbide tooling is brittle and susceptible to damage from improper handling or interrupted cuts. Follow the machine manufacturer and tooling supplier recommendations for speeds and feeds appropriate to the workpiece material.
