Carbide Inserts - Millers Tooling, Brisbane, Australia - wholesale turning insert

The polygon shank tool holders of the Quick Change line are designed to be compliant with the ISO 26623-1 standard for toolholding systems. As such, they can be used with any coupling system that is based on the ISO 26623-1 standard, enabling quick & easy tool changes.

Coated carbide inserts became popular in the industry. But cermet inserts have their advantages in some areas because of the features. Cermet inserts are used for finishing applications in stable conditions.

Tool holders for cutting internal threads/grooves. These holders improve on the basic internal tool holders by adding an integrated coolant bore. The coolant fluid helps to evacuate the chips, which helps to maximize tool performance, as well as extend the life of the insert.

In the 1970s the coated carbide inserts (CVD coated exactly) were introduced in the market. The combination of a tungsten carbide substrate with a thin layer of coating resulted in a product that could achieve a cutting speed not far from the cermet with significantly higher toughness.

Our range of grooving inserts is designed to work with standard Carmex thread turning tool holders, and deliver high-quality grooves. These inserts are manufactured using a variety of blank sizes: 6 mm (5/32″), 8 mm (3/16″), 11 mm (1/4″), 16 mm (3/8″), 22 mm (1/2″), and 27 mm (5/8″).

Cermet inserts (cermet cutting tools: Sandvik, Kennametal, GNRCERA, etc) were introduced in the 1950s. In those early days, carbide inserts were not coated and the cermet inserts enabled machining at much higher cutting speeds.

A unique product line of external tool holders equipped with an internal coolant – enabling a flow of coolant to the cutting edge. This reduces the temperature of the cutting edge while machining, helping to extend the life span of the tool. Additionally, the coolant fluid aids in removal of the chips during operation – improving the cutting performance.

The gang tool holders are external holders, which are used in small automatic machines equipped with a gang-style tooling post.

Tool holders for cutting external threads/grooves. These holders are specially designed to operate in an upside-down position, while keeping the height of the cutting edge at the same level as standard tool holders.

Cermet inserts (Kyocera, Sandvik, Kennametal, GNRCERA) offer a good solution for finishing applications in turning and grooving in stable conditions. In this situation, cutting speed can be about 10%-20% higher compared with coated carbide grades (CVD coated), still get a better surface finish.

Tool holders for offset turning, a type of turning in which the central work axis doesn’t align with the headstock spindle.

Nowadays, the main roles of cermet inserts (cermet cutting tools) in the market include Kyocera, Sandvik, Kennametal, GNRCERA, Sumitomo, Tungaloy, Mitsubishi, Iscar, Seco.

Tool holders for internal turning jobs. Unlike the standard holders that use a 1.5° helix angle, the tool holders that belong to the current product line use 3.5°.

Cermet inserts (Mitsubishi, GNRCERA, Sumitomo, Iscar), or cermet cutting tools (Kyocera, Sandvik, Kennametal, GNRCERA, Tungaloy) offer a good solution for finishing applications in turning and grooving in stable conditions.

Tool holders for turning inserts. The holders that belong to the current line of products support only external threads/grooves.

Typically, one would consider using such a tool holder in case of a large-pitch thread with a relatively small diameter.

Tool holders for turning inserts. The holders that belong to the current line of products support only internal threads/grooves.

These carbide shank bars can be used to cut internal threads/grooves. They are especially well-suited for deep small bores with a long overhang, or for use in other situations, where chatter and deflection are expected. These bars have an integrated coolant bore, which helps with chip evacuation. This helps to maximize tool performance, as well as extend the life of the insert.
