Kennametal 4149130 Solid Carbide Jobber Drill 3.20 Mm

Product Description

The KENNAMETAL 4149130 is a solid carbide jobber-length drill bit designed for high-performance drilling in demanding materials. It carries a 3.20 mm diameter, a 140-degree point angle, and a multilayer TiAlN coating that extends tool life in abrasive cutting conditions. The straight cylindrical shank measures 6 mm in diameter, and the overall length is 66.00 mm. Right-hand cut with a regular spiral flute geometry, this drill is suited for machine tool applications in production shops, job shops, and maintenance environments where consistent hole quality and tool longevity are required.

This drill is built for cutting steel, stainless steel, cast iron, and aluminum and non-ferrous materials. The 5xD flute-to-diameter ratio and tapered web configuration support chip evacuation in deeper drilling passes. Coolant-through capability makes it compatible with CNC machining centers and drill presses equipped with internal coolant delivery. Conforming to DIN 6537K, it fits standard tool holders accepting a 6 mm straight shank. Typical applications include precision hole drilling in fabrication, production machining, and general metalworking operations.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive workpiece materials
• Multilayer TiAlN coating reduces heat buildup and extends cutting life in steel and stainless steel
• 140-degree point angle improves centering and reduces thrust force on entry
• Coolant-through design supports internal coolant delivery for chip flushing and heat management
• Regular spiral flute with tapered web configuration promotes efficient chip evacuation
• Conforms to DIN 6537K specification for consistent dimensional standards

Compatibility

Designed for use in CNC machining centers and drill presses accepting a 6 mm straight cylindrical shank. Rated for primary workpiece materials including steel, stainless steel, cast iron, and aluminum and non-ferrous materials.

Installation Notes

Installation is performed by machinists or toolroom technicians in a controlled machine tool environment. Secure the shank fully in a collet, drill chuck, or hydraulic toolholder rated for the shank diameter before operation. Verify spindle speed and feed rate are appropriate for the workpiece material and drill diameter before cutting. Do not exceed the maximum drilling depth of 23.00 mm without retracting to clear chips.
