Kennametal 3952347 Indexable Drill Body Weldon Shank Ksem Plus

Product Description

The KENNAMETAL 3952347 is an indexable drill body in the KSEM Plus series, designed for high-performance deep-hole drilling in metal cutting applications. It features a Weldon Flat shank with two flats for positive drive and anti-rotation security during heavy-duty drilling cycles. The body accepts an FDS56 head connection and supports through-coolant delivery, keeping the cutting zone clear of chips and managing heat at the insert. With a 2-inch shank diameter and a 3xD drill depth-to-diameter ratio, this body is built for rigid setups in CNC machining centers and production drilling environments. A clamping screw and pipe plug are included.

This indexable drill body is suited for production machining in industrial and manufacturing environments. The KSEM Plus series targets applications in aerospace, energy, and general metalworking where consistent hole quality and high material removal rates are required. The Weldon Flat shank interface fits SSF-style toolholders and is appropriate for horizontal and vertical machining centers running moderate to high spindle loads. Through-coolant capability makes it well suited for steels, stainless alloys, and other materials that generate significant heat during drilling.

Key Features

• KSEM Plus series indexable drill body with FDS56 head connection for repeatable insert seating
• Weldon Flat shank with two flats provides positive drive and resists rotation under load
• Through-coolant channels deliver coolant directly to the cutting edge for chip evacuation and thermal control
• 3xD depth-to-diameter ratio supports deep-hole drilling in a single pass without peck cycles
• SSF toolholder style compatible with standard CNC machining center interfaces
• Includes clamping screw and pipe plug for ready-to-mount installation

Compatibility

Designed for use with KSEM Plus series insert heads using the FDS56 head connection. Compatible with SSF-style toolholders accepting a 2-inch Weldon Flat shank.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician familiar with indexable drilling systems. Ensure the machine spindle is fully stopped and all energy sources are locked out before mounting or removing the drill body. Confirm that the toolholder bore is clean and within specified tolerance before clamping. Follow the toolholder manufacturer torque guidelines for Weldon Flat setups to prevent slippage or shank damage during high-feed drilling cycles.
