Kennametal 6205876 Hex Drive Bit Shell Mills 3mm

Product Description

The KENNAMETAL 6205876 is a 3mm hex drive bit designed for use with shell mills in indexable milling applications. It transmits torque from the spindle to the shell mill cutter, providing a secure mechanical drive connection during face milling and shoulder milling operations. The hex drive configuration measures 3mm across and the bit body dimensions are 1.18 inches wide by 4.72 inches in length. At 1.23 pounds, it is a solid, durable component intended for installation and service by machinists and tooling technicians working with modular milling tooling systems.

This hex drive bit is used in indexable shell mill setups on CNC machining centers and manual milling machines. It seats between the arbor and the shell mill body to transfer rotational drive force. Typical applications include face milling, shoulder milling, and surface finishing operations in production and job-shop environments. It ships in a quantity of one per package and is suitable for both initial tooling builds and replacement of worn or damaged drive bits in existing shell mill assemblies.

• Compatible with indexable shell mill tooling systems
• Compact body at 1.18 inches wide by 4.72 inches in length for straightforward installation
• Sold individually, allowing single-unit replacement without buying in bulk
• Durable construction suited to production milling environments

Compatibility

Designed as an OEM-style replacement or spare drive bit for indexable shell mill tooling assemblies requiring a 3mm hex drive interface.

Installation Notes

Installation and replacement of shell mill drive bits should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is locked out before removing or seating the drive bit. Verify the hex drive seats fully and flush in the corresponding arbor pocket before mounting the shell mill cutter. Inspect the drive bit for wear or deformation before each use to prevent tool runout or cutter damage.
