Kennametal 2263185 Grooving Cutoff Toolholder A4SM

Product Description

The KENNAMETAL 2263185 is a right-hand indexable grooving and cutoff toolholder in the A4SM series, designed for precision grooving and parting operations on CNC lathes and turning centers. It accepts A4..08.. series inserts secured by a clamp-style holding method, providing rigid, repeatable insert positioning. The toolholder supports a minimum groove width of 8 mm (0.315 inches) and a maximum depth of cut of 20 mm (0.79 inches). With a 1 x 1 inch square shank and an overall length of 6 inches, it fits standard tool posts and turret stations common in production turning environments. Machinists, toolroom technicians, and CNC operators working in metalworking and machining applications install this holder.

This toolholder is suited for external grooving, recessing, and cutoff work on ferrous and non-ferrous workpieces. The A4SM style is a standard configuration for shops running high-volume turning operations where consistent insert indexing and secure clamping reduce downtime. It is appropriate for use on medium to large CNC lathes where a 1-inch square shank toolholder fits the turret or tool post. The right-hand designation means the cutting action feeds from right to left, consistent with standard OD turning setups on conventional and CNC machines.

Key Features

• Right-hand cutting orientation for standard OD grooving and cutoff operations
• Clamp-style insert holding method for rigid, repeatable insert seating
• Compatible with A4..08.. series inserts with an insert seat size of 8.0
• 1 x 1 inch square shank fits standard turret and tool post stations
• Maximum depth of cut of 20 mm (0.79 inches) for deeper grooving and parting
• No coolant-through design — external coolant delivery applies

Compatibility

Designed for use with A4..08.. series indexable inserts as specified by the manufacturer. Insert seat size is 8.0. Confirm insert geometry and grade selection against the workpiece material and cutting parameters before use.

Installation Notes

Installation is performed by a machinist or toolroom technician familiar with CNC lathe tooling setup. Ensure the machine is powered down and the turret is in a safe position before inserting or removing the toolholder. Torque the turret clamp bolts according to the machine manufacturer's specifications. Verify insert seating and clamp engagement before running the spindle, and confirm tool offset data is entered correctly in the CNC controller before the first cut.
