Kennametal 1198599 Straight-flute Drill Bit 6.40mm Carbide

Product Description

The KENNAMETAL 1198599 is a straight-flute solid carbide drill bit engineered for precision drilling in cast iron and non-ferrous metal workpieces. Built to DIN 6537L specification, this 6.40 mm diameter bit features a 130-degree split point with web thinning for reduced thrust and accurate hole entry. The bright, uncoated carbide construction provides clean chip evacuation in materials where coatings can cause adhesion issues. With a 53.00 mm flute length and 91.00 mm overall length, it is sized for moderate-depth production drilling applications. Internal coolant-through capability via round coolant holes supports extended tool life in high-cycle CNC environments. Installed by machining professionals and tool-room technicians.

This drill bit is suited for CNC machining centers, drilling stations, and multi-spindle setups handling cast iron and non-ferrous metals in both production and job-shop environments. The 8.00 mm shank diameter seats in standard collets, drill chucks, and toolholders configured for that shank size. Maximum drilling depth reaches 43.00 mm, making it appropriate for through-hole and blind-hole operations within that depth range. The Series B411 designation identifies this as part of a coordinated Kennametal straight-flute carbide drill line.

Key Features

• Solid carbide construction for rigidity and wear resistance in cast iron and non-ferrous metals
• 130-degree split point reduces entry thrust and improves positional accuracy
• Web-thinned geometry lowers cutting forces and aids chip breakage
• Coolant-through design with round coolant holes supports internal flood or mist cooling
• Right-hand cutting, 2-flute configuration for efficient chip evacuation in straight-flute applications
• DIN 6537L specification ensures dimensional consistency for toolholder fitment

Compatibility

Designed for use in CNC machining centers and drilling equipment accepting an 8.00 mm shank. Rated for primary use in cast iron and non-ferrous metals per the manufacturer specification. Consult toolholder documentation to confirm collet or chuck compatibility before installation.

Installation Notes

Installation and setup should be performed by a qualified machinist or toolroom technician familiar with CNC toolholding systems. Ensure the machine spindle is fully stopped and the tool changer or spindle is locked out before inserting or removing the drill bit. Confirm the 8.00 mm shank is fully seated and properly torqued in the toolholder per the toolholder manufacturer instructions. Verify coolant-through passages are clear and coolant pressure is set appropriately for the application before beginning a drilling cycle.
