266RG-16MM01A200M 1135 Tungsten Carbide Inserts CNC Cutting Tools

Sandvik 266RG-16MM01A200M 1135 is a core thread turning insert from the CoroThread® 266 series by Sandvik Coromant (Sweden), developed specifically for external thread turning processes in metalworking. Featuring a cemented carbide substrate with both high toughness and wear resistance, advanced PVD coating technology, and an optimized geometric structure, it can stably machine various metal materials at medium to low cutting speeds. It is particularly suitable for working conditions requiring high tool toughness such as interrupted cutting and grooving to center, providing a solution for dual improvement of efficiency and quality in the precision manufacturing field.

The insert model code accurately reflects performance characteristics, and each parameter collaboratively ensures processing stability. The key technical specifications are as follows:

The grade 1135 cemented carbide substrate adopts an ultra-fine grain structure, which has excellent fracture toughness and can withstand impact loads during interrupted cutting without chipping. Combined with TiAlN PVD coating, the surface hardness reaches above HV3000, and the friction coefficient is as low as 0.3, which can significantly reduce cutting heat generation. The tool life is extended by 1.5-2 times compared with traditional coated tools. This combination of "high-toughness substrate + low-friction coating" performs particularly well in machining difficult-to-cut materials such as stainless steel and alloy cast iron.

The insert adopts a negative rake angle design and type A chip breaker structure, which can accurately control the flow direction and shape of chips to avoid chip entanglement on workpieces or tools. The 60° thread profile angle machining accuracy complies with ISO 5864 standards, and the thread tolerance grade can reach 2A, meeting the strict requirements for thread fit accuracy in precision machinery manufacturing. In addition, the 1.2mm cutting edge radius design effectively reduces the cutting edge wear rate while ensuring the machining surface roughness (Ra≤1.6μm).

According to ISO application range standards, this insert can cover five major material categories: P15-P45 (steel), M15-M35 (stainless steel), K15-K35 (cast iron), S15-S35 (heat-resistant alloy), and N15-N35 (non-ferrous metal), specifically including low-carbon steel, quenched and tempered steel, martensitic stainless steel, ductile iron, superalloy, etc. The multi-material compatibility reduces the frequency of tool replacement for enterprises and greatly improves equipment utilization.

• Automotive Component Manufacturing: Used for external thread machining of engine crankshafts and gearbox gear shafts, maintaining stable thread accuracy even under interrupted cutting conditions.
• Construction Machinery Field: Machines high-strength threaded parts such as hydraulic cylinder piston rods and connecting bolts, adapting to the processing needs of alloy structural steels such as 42CrMo.
• Oil Machinery Industry: Handles thread machining of drill pipe joints and wellhead equipment, withstanding the cutting challenges of high-hardness alloy materials.
• General Machinery Machining: Suitable for batch thread turning of general parts such as motor shafts and pump flanges, achieving a balance between efficiency and precision.

By extending tool life (average number of workpieces processed per edge increased by 30%) and shortening tool change time (single tool change time ≤ 2 minutes), this insert can increase the comprehensive processing efficiency of the production line by 15%-20%. In terms of cost control, the design of 3 effective cutting edges reduces the unit edge cost by about 40%. Combined with Sandvik's original 3-year warranty service, it further reduces the procurement risk for users.

As a core component of Sandvik Coromant's thread machining solution, 266RG-16MM01A200M 1135, with its excellent performance stability and wide applicability, has become an ideal choice for modern metal processing enterprises to achieve efficient, precise and low-cost production.
