Kennametal 2649384 Drill Bit 11/16 Inch Solid Carbide Tialn

Product Description

The KENNAMETAL 2649384 is a screw machine length drill bit engineered for high-performance metal cutting in demanding production environments. Built from solid carbide and coated with a multilayer TiAlN finish, this bit delivers extended tool life and thermal resistance when drilling cast iron and steel. The 140-degree point angle reduces thrust and improves entry accuracy, while the web-thinned, parallel-web geometry minimizes cutting resistance at the chisel edge. At 4.8425 inches overall length with a 2.874-inch flute length, this stub-length format provides rigidity over longer drill bits, making it a reliable choice for high-cycle production drilling applications.

This drill bit is designed for use in CNC machining centers, drill presses, and production screw machines where tight tolerances and repeatability are required. The straight cylindrical shank at 0.7087 inches (18.00 mm) diameter seats securely in standard collets and chucks. Primary workpiece materials are cast iron and steel. With coolant-through capability, it is well suited for deep-hole work where chip evacuation and heat management are critical. Maximum drilling depth is 2.008 inches. It follows DIN 6537K specification and is classified under Series B976.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous materials
• Multilayer TiAlN coating provides thermal and oxidation resistance at elevated cutting speeds
• 140-degree point angle reduces entry thrust and improves hole location accuracy
• Web-thinned parallel web reduces cutting force at the chisel edge
• Coolant-through design supports chip flushing and heat control in deep-hole drilling
• Straight cylindrical shank compatible with standard collet and drill chuck systems

Compatibility

Designed as a screw machine length replacement drill bit for production drilling applications in cast iron and steel, conforming to DIN 6537K specification under Series B976.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Verify the shank diameter matches the collet or chuck bore to prevent runout. Do not exceed the recommended maximum drilling depth of 2.008 inches without retracting to clear chips, especially in blind-hole applications.
