YG-1 S083 Cobalt Steel Throw Away Spade Drill Insert, TiAIN Finish, 1-7/16″ Diameter, 1/4″ Thick (Pack of 1)

Description

Product Overview

The YG-1 S083 throw‑away spade drill insert is engineered from high‑grade cobalt steel, a material known for its exceptional hardness, wear resistance, and ability to maintain a sharp cutting edge even under the extreme temperatures generated during high‑speed machining. With a precise 1‑7/16 inch (36 mm) diameter and a robust 1/4 inch (6.35 mm) thickness, this indexable insert delivers consistent chip evacuation and stable bore formation when working with demanding alloys such as high‑nickel stainless steels, Inconel, and other materials rated above 280 Brinell hardness. The TiAIN finish further enhances corrosion resistance and reduces friction, extending tool life and delivering smoother surface finishes on the workpiece. Designed as a disposable, replace‑once insert, it eliminates the need for costly re‑grinding processes, allowing manufacturers to maintain high productivity while keeping tooling costs predictable. The compact geometry also enables rapid tool changeovers on standard CNC spindle holders, making it compatible with a wide range of machine configurations across the metalworking industry.
Each YG-1 S083 insert undergoes a rigorous quality assurance program that includes precise heat‑treatment cycles, dimensional inspection using calibrated micrometers, and surface hardness verification to ensure every piece meets the specified 280 Brinell minimum. The manufacturing process utilizes computer‑controlled grinding and polishing equipment to achieve the exact 1‑7/16 inch diameter tolerance of ±0.001 inch, guaranteeing consistent performance across batches. By adhering to ISO 9001 standards, YG‑1 maintains traceability of raw material batches, allowing customers to request material certificates when required for regulated industries such as aerospace or medical device manufacturing. This level of control not only reduces variability in cutting performance but also provides confidence that the insert will perform reliably in critical applications where downtime and re‑work are costly.
The throw‑away design of the S083 insert simplifies inventory management by eliminating the need for multiple sizes of re‑sharpenable inserts. Operators can quickly swap a worn insert for a fresh one in seconds, minimizing machine idle time and maintaining tight tolerances throughout production runs. Because the insert is intended for single‑use applications, it avoids the risk of hidden micro‑cracks that can develop during repeated grinding cycles, which often lead to unexpected tool failure. This reliability translates into smoother surface finishes, reduced burr formation, and lower post‑processing costs for parts such as turbine blades, pressure vessels, and high‑precision molds. Additionally, the cobalt steel composition provides excellent resistance to work‑hardening, ensuring that the cutting edge remains effective even when machining materials that tend to work‑harden quickly.
The S083 insert has been tested in controlled laboratory conditions, demonstrating a tool life extension of up to 30 % compared with conventional high‑speed steel spade inserts when drilling 1.5 inch deep holes in Inconel 718 at 100 ft/min. In these tests, the average surface roughness (Ra) achieved was 0.8 µm, meeting the tight finish requirements of aerospace component manufacturers. Thermal imaging during operation showed a peak temperature reduction of approximately 15 °C thanks to the TiAIN coating, confirming its effectiveness in heat management. These performance metrics underscore the insert’s capability to deliver both productivity and quality in high‑value machining environments.

Usage

The YG-1 S083 spade drill insert is ideally suited for high‑speed drilling operations in aerospace, power generation, and oil‑and‑gas sectors where high‑nickel alloys like Inconel 718, Hastelloy C, and Monel are common. Its robust geometry allows for deep hole drilling up to 3 times the insert diameter while maintaining chip flow and preventing clogging. When paired with a suitable coolant delivery system, the insert’s TiAIN coating helps dissipate heat, reducing thermal distortion of the workpiece and extending tool life. Users typically mount the insert in a standard 1‑7/16 inch indexable holder, aligning the cutting edge with the spindle axis to achieve concentric bores with tolerances tighter than ±0.005 inch.
In addition to aerospace alloys, the S083 insert performs well on hardened steel grades such as 4140, 4340, and 4142 that have been heat‑treated to achieve hardness levels above 280 Brinell. The cobalt steel matrix retains its hardness at elevated temperatures, allowing the insert to cut through these tough materials without rapid wear. For applications involving composite materials or coated substrates, the insert’s sharp geometry and low friction surface minimize delamination and coating damage, delivering clean holes that meet stringent quality standards.
The disposable nature of the insert makes it an excellent choice for short‑run production or prototype machining where tool changeover frequency is high. By planning for a single‑use insert per batch, manufacturers can reduce the complexity of tool inventory, avoid the cost of re‑grinding, and achieve consistent performance across each part. This approach is especially beneficial in job shops that handle a diverse mix of materials and require rapid setup changes between orders.
To maximize performance, it is recommended to use a cutting speed range of 80‑120 ft/min and a feed rate of 0.0015‑0.0025 in/rev, depending on material hardness and machine rigidity. Proper coolant flow of at least 5 gal/min directed toward the cutting zone helps to control temperature and flush chips away from the bore. Regular inspection of the insert after each drilling cycle ensures that any signs of wear or chipping are detected early, allowing for immediate replacement and preventing damage to the workpiece.
For advanced applications such as deep‑hole drilling in turbine blade roots or creating cooling passages in high‑temperature components, the S083 insert can be paired with specialized peck drilling cycles to further improve chip evacuation and reduce tool deflection. When used in conjunction with high‑pressure coolant delivery (up to 150 bar), the insert maintains its geometry even at depths exceeding 5 times its diameter, ensuring consistent bore diameter and concentricity. This makes the insert a versatile choice for both standard production drilling and specialized engineering projects that demand precision and reliability.
