Kennametal 1094527 Indexable Turning Toolholder SDJCR103

Product Description

The KENNAMETAL 1094527 is an indexable turning toolholder in the SDJCR103 style, designed for use with DC-style insert geometry at a 32.5-degree lead angle. It uses a screw clamping method to lock the insert securely in place during turning operations. The toolholder features a right-hand orientation, a neutral rake angle of 0 degrees, and accepts inserts with a 3/8-inch (0.375-inch) inscribed circle. The 5/8-inch square shank measures 0.625 inches wide by 0.630 inches tall, with an overall length of 4 inches. Built from steel, this toolholder is suited for CNC and manual lathe applications where consistent insert retention and precise geometry are required. Licensed machinists and toolroom technicians are the primary end users.

This toolholder is used in external turning operations on CNC lathes and manual engine lathes across production machining, job shop, and maintenance environments. The SDJC toolholder style is typically applied when machining ferrous and non-ferrous workpieces that require a moderate lead angle and neutral rake for stable cutting action. It is compatible with DC.. 3252 series inserts, and the screw-on series design allows for fast, repeatable insert indexing. The 0.75-inch back-of-bar to cutting edge dimension and 0.88-inch head length suit both finishing and medium-duty turning passes.

Installation Notes

Installation is performed by a machinist or toolroom technician. Before mounting or indexing inserts, ensure the lathe spindle is fully stopped and locked out per facility lockout/tagout procedures. Seat the toolholder securely in the tool block or turret and torque the clamping hardware according to the machine tool manufacturer specifications. Inspect the insert seat and clamping screw for wear or debris before each insert change.
