Kennametal 2649376 Carbide Drill Bit 13/32 Inch Tialn

Product Description

The KENNAMETAL 2649376 is a screw machine length drill bit engineered for high-performance metal cutting in industrial and machining applications. Built from solid carbide and coated with a multilayer TiAlN finish, this bit delivers extended tool life and heat resistance in demanding cuts. The 140-degree point angle and web-thinned geometry reduce thrust force and improve centering accuracy at entry. With a straight cylindrical shank measuring 0.4724 inches in diameter and an overall length of 4.0157 inches, the 2649376 fits standard toolholders used on CNC machining centers and drill presses.

This drill bit is designed for use in metalworking and machining operations where short, rigid tooling is required. Its primary workpiece materials are cast iron and steel, making it well-suited for production environments, job shops, and maintenance machining. The coolant-through design allows internal coolant delivery to the cutting zone, reducing heat buildup during deep or continuous drilling cycles. The Series B976 designation conforms to DIN 6537K specifications, making it compatible with metric tooling setups as well.

Key Features

• Solid carbide construction for rigidity and wear resistance in cast iron and steel
• Multilayer TiAlN coating provides heat and oxidation resistance at elevated cutting speeds
• 140-degree point angle with web thinning reduces entry thrust and improves hole accuracy
• Coolant-through design supports internal coolant delivery for extended run times
• Straight cylindrical shank at 0.4724 inches diameter fits standard drill chucks and toolholders
• Conforms to DIN 6537K specification for dimensional consistency

Compatibility

Designed as a high-performance replacement drill bit for machining applications requiring a 13/32 inch (0.4062 inch) diameter, DIN 6537K-compliant screw machine length carbide drill. Suitable for use in CNC machining centers and drill presses with straight-shank toolholding.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Verify the shank seats fully and concentrically in the toolholder and confirm proper coolant-through connections are active before beginning drilling operations. Follow the machine manufacturer and OSHA guidelines for tooling setup and workpiece fixturing.
