YG-1 Cobalt Steel Spade Drill Insert 7/8″ TiN Finish S061

Description

Product Overview

The YG-1 S061 throw‑away spade drill insert is engineered from premium cobalt steel, a material renowned for its exceptional hardness and heat‑resistance properties. A titanium nitride (TiN) finish further enhances surface durability, providing a low‑friction interface that extends tool life even under the most demanding machining conditions. Sized at a 7/8″ (22.2 mm) diameter and a thickness of 5/32″ (3.97 mm), this insert delivers a precise cutting geometry that promotes efficient material removal while maintaining dimensional stability. Packaged in a compact 1.6 × 1.6 × 0.2 in. box, the insert is lightweight at just 0.01 oz, making it easy to handle and store. Designed for high‑nickel alloys and materials with hardness ratings above 280 HB, the S061 offers a reliable solution for manufacturers seeking consistent performance and reduced downtime.

Usage

In industrial environments where precision and speed are paramount, the YG-1 S061 spade drill insert excels. It is ideally suited for machining high‑nickel alloys such as Inconel, Hastelloy, and other corrosion‑resistant steels commonly used in aerospace, power generation, and chemical processing applications. The insert’s robust cobalt steel composition enables it to withstand the elevated temperatures generated during high‑speed drilling, while the TiN coating reduces friction, helping to achieve smoother cuts and lower tool wear. Its throw‑away design simplifies tool changes: operators can quickly replace a worn insert without the need for complex re‑sharpening procedures, thereby minimizing machine idle time. The insert’s compact dimensions also allow it to be used in tight‑space CNC machines and conventional lathes, making it a versatile choice for a wide range of machining setups.

FAQ

What materials can the YG-1 S061 insert machine effectively?

The insert is optimized for high‑nickel alloys such as Inconel and Hastelloy, as well as other hard materials with a Brinell hardness above 280 HB, including stainless steels and titanium alloys.

How does the TiN coating benefit the drilling process?

TiN provides a hard, low‑friction surface that reduces tool wear, lowers cutting forces, and helps maintain consistent dimensions during high‑speed drilling, resulting in longer tool life and better surface finish.

Can the insert be reused after a single use?

While the S061 is designed as a throw‑away insert for maximum efficiency, it can be reused if the cutting edge remains intact and the coating is undamaged. However, for optimal performance, replacement after each machining cycle is recommended.

What are the recommended cutting speeds for this insert?

Typical cutting speeds range from 80 to 120 m/min depending on the workpiece material and machine rigidity. Adjustments may be needed based on specific alloy compositions and coolant usage.

Is there any special handling required for storage?

Store the inserts in a dry, clean environment away from abrasive contaminants. The compact packaging protects the TiN coating, but keeping them in a sealed container further prevents oxidation and physical damage.
