Kennametal 1913052 Screw Machine Drill Bit 3mm Carbide

Product Description

The KENNAMETAL 1913052 is a solid carbide screw machine length drill bit designed for high-productivity short-hole drilling in metalworking applications. Built to DIN 6537K standards, this bit features a 3.00 mm diameter, a 140-degree split point for accurate self-starting entry, and a TiAlN coating that extends tool life in abrasive and high-temperature cutting conditions. The web-thinned, parallel web geometry reduces thrust load and improves chip evacuation through the 2-flute regular spiral configuration. With an overall length of 62.00 mm and a 6.00 mm straight cylindrical shank, this bit fits standard drill chucks and tool holders used in CNC machining centers, drill presses, and screw machines.

This drill bit is suited for cutting steel, cast iron, aluminum, and non-ferrous materials in production machining environments. The screw machine length format — shorter overall length with reduced overhang — provides added rigidity for close-tolerance drilling in fixtures and turret setups. Maximum drilling depth is 14.00 mm, and the 20.00 mm flute length supports chip clearance within that range. Machinists, tool room operators, and CNC programmers working in job shop or production settings will find this bit appropriate for precision bore operations requiring consistent entry and exit geometry.

Key Features

• Solid carbide construction for rigidity and wear resistance in metalworking
• TiAlN coating improves heat resistance and tool life in steel and cast iron
• 140-degree point angle with web thinning reduces thrust and centers accurately
• Screw machine length design increases rigidity and reduces deflection
• DIN 6537K and DIN 6535 compliant for standardized shank and geometry
• Regular spiral flute geometry supports chip evacuation in through and blind holes

Compatibility

Designed for use with steel, cast iron, aluminum, and non-ferrous workpiece materials as noted in the product specifications. The 6.00 mm straight cylindrical shank is compatible with standard drill chucks and collet holders accepting that shank diameter, conforming to DIN 6535 and DIN 6537 standards.

Installation Notes

Installation and use of this drill bit is performed by qualified machinists or tool room technicians. Before mounting, confirm the tool holder or chuck is rated for the 6.00 mm shank diameter and that the spindle is fully stopped before bit changes. Use appropriate cutting fluid or dry cutting conditions per the workpiece material and machine manufacturer recommendations. Do not exceed the maximum drilling depth of 14.00 mm without retracting to clear chips.
