Kennametal 6389501 Kentip Fs Indexable Drill Body 12xd

Product Description

The KENNAMETAL 6389501 is an indexable drill body in the KenTIP FS series, designed for deep-hole drilling applications requiring a 12xD depth-to-diameter ratio. The body accepts interchangeable KenTIP FS (KTFS) insert tips, allowing the cutting head to be swapped without removing the drill body from the spindle. With a 20mm shank diameter and an overall length of 269mm, this drill body suits CNC machining centers and drilling operations where extended reach and insert flexibility reduce tooling downtime. Machinists and tooling technicians working in metalworking, aerospace, and general manufacturing environments are the primary installers and users.

This drill body is suited for production drilling in ferrous and non-ferrous materials where deep-hole capability is required in a single pass. The 12xD configuration allows drilling to depths significantly greater than standard drill bodies without the need for peck drilling cycles in many applications. Internal coolant delivery, typical of the KenTIP FS platform, supports chip evacuation at depth. It fits machining centers with appropriate spindle interface and coolant-through capability.

Key Features

• 12xD depth-to-diameter ratio for deep-hole drilling in a single body
• KTFS toolholder style accepts KenTIP FS indexable insert tips
• 20mm shank diameter for rigid, concentric clamping
• Overall length of 269mm with a flute length of 205.60mm
• 50mm shank length provides secure chuck or collet engagement
• Indexable tip design reduces cost-per-hole by replacing inserts rather than full drill bodies

Compatibility

Designed for use with KenTIP FS (KTFS) series indexable drill tips. Consult KENNAMETAL tooling data for the correct insert tip diameter and grade pairing for this drill body.

Installation Notes

Installation and setup should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before mounting or removing the drill body. Verify shank-to-holder interface fit and recommended clamping torque per the machine tool and holder manufacturer specifications. Confirm coolant-through passages are clear before beginning drilling operations.
