Kennametal 4112492 Solid Carbide Jobber Drill 11mm Tialn

Product Description

The KENNAMETAL 4112492 is a solid carbide jobber-length drill designed for high-performance hole-making in steel and similarly demanding workpiece materials. It features a 135-degree split-point geometry and a multilayer TiAlN (titanium aluminum nitride) coating that improves heat resistance and extends tool life in abrasive and high-speed applications. The drill measures 11.00 mm in diameter with an overall length of 4.6457 inches (118.00 mm) and a flute length of 2.7953 inches (71.00 mm). Coolant-through capability supports chip evacuation and thermal management during deep-hole operations. This drill is sized at 5xD flute-by-diameter ratio and conforms to DIN 6537K specification. It is installed and operated by machinists and metalworking professionals in CNC and manual drilling applications.

The 4112492 is suited for production drilling in steel across CNC machining centers, drill presses, and multi-spindle setups. The straight cylindrical shank with a 12.00 mm shank diameter fits standard drill chucks and collet holders without modification. A maximum drilling depth of 2.2047 inches (56.00 mm) makes it appropriate for through-holes and blind-hole applications within that depth range. The 2-flute regular spiral geometry promotes consistent chip flow. This drill is a strong fit for production shops running ferrous metal components where tool life and dimensional accuracy are critical.

Key Features

• Solid carbide construction in material grade KCPK15 for rigidity and wear resistance in steel cutting
• Multilayer TiAlN coating improves thermal resistance and extends tool life in high-speed drilling
• 135-degree standard point geometry reduces entry thrust and improves self-centering
• Coolant-through design supports chip evacuation and heat control at depth
• DIN 6537K specification ensures dimensional conformance for repeatable results
• Right-hand cut, 2-flute regular spiral flute for efficient chip removal

Compatibility

Designed for use in CNC machining centers and conventional drill presses equipped with chucks or collet holders accepting a 12.00 mm straight cylindrical shank. Primary workpiece material is steel; the DIN 6537K specification and KCPK15 grade are matched to ferrous metal drilling applications.

Installation Notes

Installation and operation should be performed by qualified machinists familiar with carbide tooling requirements. Secure the straight shank in a properly sized collet or drill chuck to the holding system manufacturer's specification before initiating spindle rotation. Carbide tooling is brittle — avoid side loads, interrupted cuts beyond the tool's rated capacity, and dropping or impact contact that can cause micro-fractures. Verify coolant-through flow is established before drilling to depth to prevent thermal damage to the cutting edge.
