Kennametal 2649367 Screw Machine Drill Bit 17/64 in

Product Description

The KENNAMETAL 2649367 is a screw machine length solid carbide drill bit designed for high-productivity drilling in ferrous and cast iron applications. Built to DIN 6537K specification, it features a 140-degree split point with web thinning for reduced thrust and improved centering at entry. The 2-flute regular spiral geometry paired with a TiAlN coating delivers excellent wear resistance and thermal stability at elevated cutting speeds. Coolant-through capability supports chip evacuation and tool life in deep-hole operations. At 3.11 inches overall length, this stub-length format provides rigidity in short-reach setups, making it a reliable choice for production drilling environments.

This drill bit is suited for drilling cast iron and steel in CNC machining centers, drill presses, and screw machine applications where rigidity and precision are required. The straight cylindrical shank at 0.315 inches diameter fits standard collet and chuck systems. The maximum drilling depth of 0.945 inches and screw machine length format make it well matched to high-volume production runs where tool deflection and cycle time matter. A right-hand cutting direction is standard for conventional spindle rotation.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• TiAlN coating for high-temperature performance and extended tool life
• 140-degree split point with web thinning reduces entry thrust and improves hole accuracy
• Coolant-through design supports chip evacuation and thermal management
• DIN 6537K specification ensures dimensional consistency
• Screw machine (stub) length format maximizes rigidity in short-reach setups

Compatibility

Designed as a direct-fit screw machine length drill bit for collet chucks and standard straight-shank drill holders accepting a 0.315-inch shank diameter. Primary workpiece materials are cast iron and steel per manufacturer specification.

Installation Notes

Installation and operation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Verify coolant-through passages are clear before initiating a drilling cycle. Follow the machine manufacturer and tooling manufacturer guidelines for speeds, feeds, and coolant pressure appropriate to the workpiece material.
