Ingersoll Cutting Tools 6243691 Cutoff Insert SFJ3 K10

Product Description

The INGERSOLL CUTTING TOOLS 6243691 is a single-end carbide cutoff insert designed for grooving and parting operations on CNC lathes and turning centers. Built to the SFJ3 series specification with a K10 carbide grade, this uncoated insert features a cutting width of 0.1181 inches and a corner radius of 0.0080 inches. The neutral lead angle and neutral hand orientation make it straightforward to apply in a wide range of setups. Clamp-style holding ensures rigid seating during high-speed cutoff passes. Machinists and tool-room technicians working with cast iron and non-ferrous metals will find this insert a reliable fit for precision parting applications.

This insert is suited for grooving and parting applications on cast iron and non-ferrous metal workpieces in both production and job-shop environments. The J chipbreaker geometry supports controlled chip formation during cutoff passes, reducing the risk of chip entanglement. The SFJ3 series is a common specification in CNC turning operations where consistent groove width and clean parting cuts are required. The single-end configuration means the insert is indexed or replaced rather than flipped, keeping setup time predictable.

• Cutting width of 0.1181 inches for consistent groove and parting dimensions
• Corner radius of 0.0080 inches for controlled edge geometry
• J chipbreaker design promotes chip control during grooving and parting passes
• Neutral lead angle and neutral hand allow flexible setup orientation
• Clamp-style insert holding method for rigid, repeatable seating in compatible toolholders

Compatibility

Designed for use in SFJ series clamp-style toolholders that accept a size 3 insert seat. Compatible with grooving and parting applications on cast iron and non-ferrous metal workpieces. Verify toolholder insert seat size and clamp style before ordering.

Installation Notes

Installation is performed by a machinist or tool-crib technician during a scheduled tool change with the machine fully stopped and the spindle locked out per facility lockout/tagout procedures. Seat the insert fully against the pocket locating surfaces before tightening the clamp to the toolholder manufacturer's specified procedure. Inspect the insert seat for chips or debris prior to installation, as contamination in the pocket can affect cutting edge height and groove width accuracy. Do not use a damaged or chipped insert, as this can cause workpiece damage or unpredictable tool behavior.
