Kennametal 4149111 Solid Carbide Jobber Drill 10.10mm

Product Description

The KENNAMETAL 4149111 is a solid carbide jobber-length drill designed for high-performance drilling in demanding production environments. Built to DIN 6537K specification, it features a 10.10 mm diameter, a 140-degree split point, and a multilayer TiAlN coating that extends tool life in abrasive and high-heat applications. The drill measures 118.00 mm overall length with a 71.00 mm flute length, providing the reach needed for most jobber-depth holes. Coolant-through capability delivers cutting fluid directly to the tip, reducing heat buildup and improving chip evacuation in deep-hole operations. This drill is specified and installed by machining professionals, toolroom technicians, and maintenance trades working with industrial drilling equipment.

The 4149111 is suited for drilling steel, stainless steel, cast iron, aluminum, and other non-ferrous materials in both CNC machining centers and conventional drill presses. Its straight cylindrical shank with a 12 mm shank diameter seats in standard collet chucks and drill holders. The 5xD flute-to-diameter ratio and regular spiral geometry support consistent chip removal across a range of feed and speed conditions. Applications include production drilling, fixture work, and maintenance machining where dimensional accuracy and tool longevity are required.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous and non-ferrous materials
• Multilayer TiAlN coating reduces friction and extends tool life at elevated cutting temperatures
• 140-degree point angle provides self-centering entry and reduces thrust force
• Coolant-through design delivers fluid directly to the cutting edge for deep-hole drilling
• DIN 6537K specification ensures dimensional conformance and interchangeability
• Tapered web configuration with regular spiral flutes promotes efficient chip evacuation

Compatibility

Compatible with drilling operations in steel, stainless steel, cast iron, aluminum, and non-ferrous materials. Fits standard straight-shank collet chucks and drill holders accepting a 12 mm shank. Designed as an OEM-grade replacement or production-use drill conforming to DIN 6537K in the 10.00 to 12.50 mm diameter range.

Installation Notes

Installation and tool changes should be performed by qualified machining or maintenance personnel with the machine spindle fully stopped and energy isolated per lockout/tagout procedures. Confirm the collet or chuck is rated for the 12 mm shank diameter and that coolant-through passages in the toolholder are clear before engaging the coolant system. Inspect the drill point and flutes for chips or damage before mounting. Do not exceed the maximum recommended drilling depth of 56.00 mm without retracting to clear chips.
