3 Tools for External Turning Modern machining operations performed on CNC machine tools and flexible production facilities require high-performance tools that provide straightforward design and application versatility. WIDIA offers an extensive range of toolholders for external turning to meet even the most exacting production demands across a broad spectrum of workpiece shapes and sizes. Whatever your operation requirements from light finishing cuts at very high cutting speeds to heavy roughing applications there is a WIDIA solution to meet your needs. The complete program includes toolholders for pin-, screw-, or clamp-type holding. Clamping System M Combined pin/wedge clamp for negative inserts. An extremely sturdy clamping system, specially designed for interrupted cuts. Protected by a carbide shim. Clamping System P Lever-type clamping system for negative indexable inserts. No interference to chip flow. Fast insert changes. P style available in metric sizes only. A2

4 Lever pin for no interference to chip flow. Combined pin and clamp locking for superior performance in tough applications. Lever pin screw for fast indexing. Clamping System S Screw clamping system for positive indexable inserts. Compact design for high reliability and cost efficiency. Carbide shim for additional tool protection. Clamping System C Height-adjustable clamp permits use of additional chipbreakers. Universal clamping system for positive indexable inserts. Robust engineering makes it easy to handle. Carbide shim for extra tool protection. A3

39 Cartridges Modern machining operations demand high-quality, high-performance toolholders that provide straightforward design and application versatility. Standard WIDIA cartridges are ideal for turning tools with one, or several, cutting edges. A wide range of cartridge sizes and styles provide numerous combinations and application possibilities. Clamping System M Combined pin/wedge clamp for negative inserts. An extremely sturdy clamping system, specially designed for interrupted cuts. The tool is protected by a carbide shim. Clamping System P Lever-type clamping system for negative indexable inserts with hole to DIN 4988 and positive round inserts more than 20,0mm in diameter. Inserts with one- and two-side chip control geometries have positive rakes from 6 to 18. Advantages of this system are fast insert changes and no interference with chip flow. P style available in metric sizes only. A38

40 Simple and secure mounting to the tool by a single cartridge clamping screw. Same clamping systems as standard turning toolholders. High accuracy on F dimension ensures proper application to minimum bore dimensions. Overall sizes to DIN and ISO are ideal for single- and multi-tooth turning, boring, and spotting tools. Precise axial and radial positioning by adjustment screws. Clamping System C Top clamping system for negative and positive indexable inserts to DIN This universal clamping system is robust and easy to handle. Some height-adjustable clamps enable the use of additional chipbreakers. A carbide shim provides additional tool protection. Clamping System S Screw clamping system for positive indexable inserts with countersunk hole to DIN Compact design using a minimum of spare parts for high reliability and cost efficiency. A carbide shim provides additional tool protection. Toolholders with cutting edge heights upwards of.625" (16,0mm) and insert ICs from.375" (9,52mm) are secured by means of a threaded bushing. A39
