In this blog, we will discuss how to identify all these key dimensions, so you will never need to check for part numbers again.

Some of the below chipbreakers are available on both negative and positive inserts but the min-max depths of cut may vary.

Tolerance dimensions are indicated by a letter ranging from A - U. Dimension A relates to the inscribed circle (IC), dimension B relates to the insert height (for pentagon, triangle, and trigon shapes – for other polygons, the dimension B relates to the distance that is measured along the bisector of the corner angle) and dimension T relates to the thickness of the insert.

Helical had experienced many years of industry-leading growth while earning superior profit margins. Would investors view this growth and margin profile as sustainable? Would investors be willing to support the capital investments required to leverage the many opportunities the Company had in front of it.

For insert shapes such as round, square, triangle & trigon, this would then indicate the diameter of the inscribed circle (IC).

Established in 2001, Helical Solutions LLC (“Helical” or the “Company”) is a leading designer and manufacturer of high performance solid carbide end mills serving North America. Helical offers more than 3,000 SKUs of both standard and custom shapes, which allow its customers to increase quality while reducing machine time when compared to using conventional cutting tools.

The relief angle for a milling insert is of paramount importance in achieving efficient and successful machining operations.

It is a 2-digit number that generally indicates the width or length, however this is only applicable to insert shapes with no IC (inscribed circle), such as rectangular and parallelograms.

The thickness of a turning insert is measured from the bottom of the insert to the top of the cutting edge. This will be shown as a 2-digit number except where the insert features a T and then a single digit number eg T3. This is due to the fact that there are more than one increment within each mm. eg 03 is 3.18mm whereas T3 is thickest at 3.97mm.

Structured as an acquisition by Harvey Tool Company, Helical’s shareholders and continuing management team were given the opportunity to invest alongside Riverside in the combined entity. Since 1985, Harvey Tool has been providing specialty carbide end mills and cutting tools to the metalworking industry. The addition of Helical to Riverside’s private equity platform brings complementary manufacturing capabilities, new customers, and a larger diameter end mill product offering to Harvey Tool.

Based on a recent successful platform investment in the Harvey Tool Company, The Riverside Company, a global private equity firm focused on acquiring and investing in growing businesses, was selected as the best new majority investor in Helical.

Bigelow, using its proprietary methodology, generated significant interest in the Company from both financial and strategic investors. Leveraging both quantitative and qualitative assessment tools to rapidly identify the most compelled investors, Bigelow was able to present an array of world-class investors to the shareholders.

Choosing the right insert shape for your turning tool is essential. The shape of the insert can affect the vibration during operation, the ability to turn complex contours, the strength of the insert and its ability to take bigger and heavier cuts.

The founder and majority shareholder, together with his daughter, also a senior executive in the business, were ready to transition their capital and roles with the Company. It was important to the shareholders that a new investor continue to invest in the Company and support the many growth opportunities that the management team wanted to pursue.

Carbon steel, as such, really isn't very suitable for production of drill bits without something added to promote hardenability and some degree of toughness.

The chip breaker is represented as 2 letters in the ISO code. The chip breaker affects the cutting resistance, if the cutting resistance is low, it can avoid chipping and fracturing of the cutting edges. Reduced cutting resistance can also decrease the tool load and heat built up. The chip breaker also determines the depth of cut the insert can take, if you are not applying the correct depth of cut then you won’t be activating the chip breaker, this can cause the swarf to build up and become stringy, some people refer to this as a bird’s nest.

All turning inserts have a unique ISO code that contains various letters and numbers – believe it or not, these actually mean something! From just looking at the ISO code you can figure out the insert’s shape, relief angle, tolerance, cross-section type, cutting-edge length, thickness, radius, and chip breaker!

Could Bigelow find the best new majority investor who would inject the necessary resources and experience to help take Helical to the next level, at the same time allowing for the founder and CEO to transition out of the business satisfying both their personal and professional objectives?

It plays a crucial role in chip formation, tool life, cutting forces, and surface finish. Understanding the influence of the relief angle and selecting the appropriate one can greatly enhance machining performance, productivity, and the quality of the finished product.

The nose radius of an insert can affect the performance. A larger nose radius can result in the use of higher feed rates, and larger depths of cut, and they can handle more pressure, making them much better for heavier metal removal. Whereas a turning insert with a smaller nose radius can only take smaller depths of cut, they also have weaker cutting edges, and they can only handle a small amount of vibration but are much better for finishing as they are sharper and have less surface contact.
