Kennametal 1913531 Drill Bit 8mm Solid Carbide Tialn

Product Description

The KENNAMETAL 1913531 is a screw machine length drill bit designed for high-performance drilling in cast iron and steel. Built from solid carbide and coated with a multilayer TiAlN finish, it delivers heat resistance and extended tool life in demanding production environments. The 140-degree point angle reduces thrust and improves chip formation on tough ferrous materials. Overall length is 3.11 inches with a flute length of 1.61 inches. Coolant-through capability supports higher feed rates and helps evacuate chips in deep-hole applications. Licensed HVAC techs, machinists, and maintenance professionals in industrial settings rely on this geometry for consistent, repeatable results.

This drill bit is suited for screw machine and short-hole drilling operations in production and maintenance settings. It targets primary workpiece materials of cast iron and steel, making it a fit for automotive, heavy equipment, and general metalworking shops. The straight cylindrical shank accepts standard drill chucks and collet toolholding systems used on CNC machining centers, drill presses, and screw machines. Its compact screw machine length profile minimizes overhang and improves rigidity at the spindle.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous materials
• Multilayer TiAlN coating for elevated-temperature performance and extended tool life
• 140-degree standard point angle reduces entry thrust and improves hole quality
• Coolant-through design supports chip evacuation and higher cutting speeds
• Web-thinned parallel web reduces cutting resistance and improves centering
• Conforms to DIN 6537K specification for consistent dimensional standards

Compatibility

Designed as an OEM-style replacement and standard production drill bit for use in straight-shank toolholding systems on screw machines, CNC drilling centers, and drill presses machining cast iron and steel workpieces. Part of KENNAMETAL Series B976.

Installation Notes

Installation and tool changes should be performed by qualified machinists or tooling technicians with the machine powered down and spindle fully stopped. Secure the straight cylindrical shank firmly in a compatible collet or drill chuck to the holding system manufacturer's recommended clamping procedure. Verify coolant-through passages are clear and coolant supply is active before beginning deep-hole drilling cycles. Do not exceed the maximum drilling depth of 1.14 inches in a single pass without retracting to clear chips.
