Kennametal 4149298 Solid Carbide Jobber Drill 10.70mm

Product Description

The KENNAMETAL 4149298 is a solid carbide jobber-length drill bit designed for high-performance drilling in demanding production environments. It features a 10.70 mm diameter, a 140-degree point angle for self-centering entry and reduced thrust, and a multilayer TiAlN coating that extends tool life under high heat and abrasion. The straight-cylindrical shank measures 12 mm in diameter and is compatible with standard drill chucks and collet holders. With an overall length of 118 mm (4.646 inches) and a flute length of 71 mm (2.795 inches), this drill suits CNC machining centers and manual drilling operations where tight tolerances are required. It is installed by machinists and tooling professionals.

This drill is engineered for use in steel, stainless steel, cast iron, aluminum, and other non-ferrous materials. It conforms to DIN 6537K specification, making it a recognized standard-compliant tooling option. The 5xD flute-to-diameter ratio and coolant-through capability make it well suited for deep-hole drilling applications where chip evacuation and heat management are critical. Typical applications include general-purpose production drilling on CNC lathes, machining centers, and drill presses in industrial and manufacturing settings.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous and non-ferrous materials
• Multilayer TiAlN coating extends tool life at elevated cutting temperatures
• 140-degree point angle reduces entry thrust and improves centering accuracy
• Coolant-through design aids chip evacuation and thermal management in deep holes
• Conforms to DIN 6537K specification for consistent dimensional standards
• Right-hand cut with regular spiral flutes and tapered web configuration

Compatibility

Designed as an OEM-style replacement and standard production drill for use in CNC machining centers, drill presses, and multi-spindle setups where a 10.70 mm straight-shank solid carbide jobber drill conforming to DIN 6537K is specified. Compatible with workpiece materials including steel, stainless steel, cast iron, aluminum, and non-ferrous alloys as stated in the product specifications.

Installation Notes

This drill bit is installed by qualified machinists or tooling technicians. Before changing tooling, power down the machine and verify the spindle has fully stopped. Ensure the shank is clean and the chuck or collet is properly sized for the 12 mm straight shank before tightening. When using the coolant-through feature, confirm coolant supply lines are connected and flow is verified before running the first cycle.
