Kennametal 1191612 Solid Carbide Die Drill Bit 0.1969 in

Product Description

The KENNAMETAL 1191612 is a solid carbide straight-flute die drill bit engineered for precision hole-making in demanding materials. Part of the B411 series, it features a 130-degree split point with web thinning for reduced thrust and accurate self-starting entry. The bright finish preserves tight diameter tolerances of +0.001 to +0.009 mm. With a 5.00 mm (0.1969 inch) cutting diameter and coolant-through capability via a round coolant-hole, this bit handles deep drilling applications up to 35.00 mm (1.3800 inches) efficiently. It is suited for machine shops, tool-and-die operations, and high-precision drilling in production environments.

This drill bit is designed for cutting cast iron and non-ferrous metals where dimensional accuracy and tool life are critical. The two-flute, straight-flute geometry promotes chip evacuation in through-hole and blind-hole applications. Coolant-through delivery keeps the cutting edge cool at elevated spindle speeds, extending tool life and maintaining hole quality in production runs. It fits standard CNC machining centers and drill presses accepting a 6.00 mm shank diameter.

Key Features

• Solid carbide construction for superior hardness and wear resistance in cast iron and non-ferrous metals
• 130-degree split point with web thinning reduces thrust and improves self-centering at entry
• Coolant-through design with round coolant hole for effective heat management during deep drilling
• Bright finish with controlled diameter tolerance of +0.001 to +0.009 mm for precise bore sizing
• Right-hand cutting, two-flute straight-flute geometry supports efficient chip clearance
• B411 series DIN 6537L specification for standardized tooling compatibility

Compatibility

Designed as an OEM-style tooling replacement and new-install die drill bit for CNC machining centers, drill presses, and die-making equipment accepting a 6.00 mm shank. Primary workpiece materials are cast iron and non-ferrous metals per the B411 series specification.

Installation Notes

Installation and operation of this drill bit should be performed by qualified machinists or tool-and-die technicians. Ensure the machine spindle is fully stopped and locked out before inserting or removing the bit from the tool holder. Verify shank seating and runout before beginning a drilling cycle. Follow applicable shop safety standards and machine manufacturer guidelines for speeds, feeds, and coolant pressure when using coolant-through tooling.
