Kennametal 6371988 Kentip Fs Indexable Drill Body

Product Description

The KENNAMETAL 6371988 is a straight-shank indexable drill body from the KenTIP FS series, designed for deep-hole drilling operations at an 8xD depth-to-diameter ratio. With a 12 mm shank diameter and an overall length of 154 mm, this drill body accepts interchangeable KenTIP FS (KTFS) insert tips, allowing fast tip changes without removing the body from the spindle. Through-coolant capability is built in, supporting high-pressure coolant delivery directly to the cutting zone to extend tip life and improve chip evacuation. This tool is intended for use by machinists and toolroom professionals on CNC machining centers and lathes.

The 6371988 is suited for production drilling in both job-shop and high-volume manufacturing environments. The 8xD depth ratio makes it appropriate for applications requiring deep, accurate holes in a single pass without peck cycles on capable machines. The straight-cylindrical shank mounts directly into standard collet chucks, hydraulic chucks, or Weldon-style holders that accept 12 mm shanks. The 104.60 mm flute length and 46 mm shank length provide the clearance and grip needed for stable, deep-reach drilling.

Key Features

• 8xD drill depth-to-diameter ratio for deep-hole capability in a single body
• 12 mm straight-cylindrical shank fits standard 12 mm collet and hydraulic chuck holders
• Through-coolant design delivers high-pressure coolant directly to the cutting edge
• Interchangeable KenTIP FS (KTFS) insert tips eliminate the need to remove the body for tip changes
• 104.60 mm flute length supports chip clearance over the full drilling depth
• Overall length of 154 mm accommodates deep-reach setups on vertical and horizontal machining centers

Compatibility

Designed for use with KenTIP FS series insert tips using the KTFS toolholder interface. Compatible with standard 12 mm collet chucks, hydraulic chucks, and shrink-fit holders. Specific tip compatibility should be confirmed against the KenTIP FS series selection guide for the target diameter and application.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool builder guidelines for tool clamping torque and runout specification. Ensure the spindle and coolant supply are fully de-energized and locked out before changing or inspecting the insert tip. Confirm through-coolant port alignment with the machine spindle coolant circuit before initiating a cutting cycle. Verify shank grip length meets the toolholder manufacturer minimum engagement specification before use.
