Kennametal 4149296 Solid Carbide Jobber Drill 10.50mm

Product Description

The KENNAMETAL 4149296 is a solid carbide jobber-length drill bit engineered for high-performance hole-making in demanding materials. Sized at 10.50 mm (0.4134 inches) in diameter, it features a 140-degree point angle and a multilayer TiAlN coating that extends tool life by resisting heat and wear at elevated cutting speeds. The overall length is 118.00 mm (4.646 inches) with a flute length of 71.00 mm (2.795 inches). The straight cylindrical shank measures 12 mm (0.4844 inches) in diameter. This drill is installed by machinists and tool-and-die professionals in CNC machining centers, drill presses, and manual machines where tight hole tolerances are required.

This jobber drill is well suited for production and maintenance drilling in steel, stainless steel, cast iron, aluminum, and other non-ferrous metals. The 5xD flute-to-diameter ratio supports chip evacuation in moderately deep holes, with a maximum drilling depth of 56.00 mm (2.205 inches). Through-spindle coolant delivery is supported, making this drill a strong fit for CNC applications where coolant-through tooling is available. It conforms to DIN 6537K specification, which is a common standard in industrial tooling procurement.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• Multilayer TiAlN coating enhances heat resistance and extends tool life at high cutting speeds
• 140-degree point angle reduces thrust force and improves self-centering on entry
• Coolant-through design compatible with through-spindle coolant delivery systems
• Right-hand cutting with regular spiral flute geometry for efficient chip evacuation
• Conforms to DIN 6537K specification for consistent dimensional standards

Compatibility

Designed as an OEM-style replacement or direct-fit tooling solution for CNC machining centers and drill presses accepting straight cylindrical shank drill bits with a 12 mm shank diameter. Primary workpiece materials include steel, stainless steel, cast iron, aluminum, and non-ferrous alloys as stated by the manufacturer.

Installation Notes

This drill is installed by qualified machinists or tooling technicians in a compatible collet, drill chuck, or hydraulic toolholder rated for 12 mm straight shanks. Confirm spindle speed and feed rate against manufacturer cutting data before use - carbide tooling is sensitive to improper parameters and can fracture under excessive load or vibration. Ensure through-spindle coolant pressure is within the machine and toolholder specifications if coolant-through operation is used. Inspect the cutting edges for chipping before each use; do not run a damaged carbide drill.
