Kennametal 4150322 13mm Solid Carbide Stub Drill Bit

Product Description

The KENNAMETAL 4150322 is a screw machine length (stub) solid carbide drill bit designed for high-productivity drilling in metalworking and machining applications. It measures 13.00 mm (0.5118 inches) in diameter with an overall length of 107.00 mm (4.2126 inches) and a 140-degree standard point angle. The multilayer TiAlN coating at the tip reduces wear and supports higher cutting speeds in ferrous and non-ferrous materials. With 2 regular spiral flutes and a straight cylindrical shank, this drill is suited for use in CNC machining centers, drill presses, and screw machine setups where rigidity and hole accuracy are critical.

This drill bit is intended for production machining environments where shorter flute length and stub body geometry provide improved rigidity over jobber-length drills. The 60.00 mm (2.3622 inches) flute length supports a maximum drilling depth of 43.00 mm (1.6929 inches). The straight shank diameter of 14.00 mm (0.5512 inches) seats into standard collet chucks or drill holders. It is commonly installed by machinists and tool-and-die professionals in job shops, manufacturing facilities, and automated production lines working with steel, cast iron, and similar materials.

Key Features

• Solid carbide construction for rigidity and extended tool life in hard materials
• TiAlN tip coating reduces friction and thermal wear at the cutting edge
• 140-degree point angle for self-centering entry and reduced thrust force
• Stub-length body (3xD flute-to-diameter ratio) provides enhanced rigidity over jobber drills
• Right-hand cut with 2 regular spiral flutes for efficient chip evacuation
• Straight cylindrical shank compatible with standard collet and drill chuck toolholding
• Conforms to DIN 6537K specification for dimensional consistency

Compatibility

Part of the KENNAMETAL B041A-CPG series, designed for use across the 11.00 mm to 13.50 mm drill diameter range in standard straight-shank toolholding systems conforming to DIN 6537K.

Installation Notes

Installation should be performed by a qualified machinist following the toolholder manufacturer's clamping specifications. Ensure the machine spindle is fully stopped and the tool is secured at the correct shank engagement depth before operation. Verify runout with a dial indicator after chucking to maintain hole tolerance. No coolant-through capability is present on this drill; apply external coolant or cutting fluid as appropriate for the workpiece material.
