Carbide Cutting Tool and Insert Introduction

Elvis Elvis

A carbide cutting tool and insert work hand in hand to make machining or drilling steel a lot easier.

The cabide tool has a very solid and sharp carbon or iron material that cuts through the hardest surfaces, while the carbide insert (usually with either a 0.4 or 0.8mm radius) gives surface finish on light cuts and more sensitive materials. Because of cutting tools and inserts, hard powder-metals, heat resistant super alloys, and bimetals are easily and more accurately machined.

Anatomy of a carbide cutting tool and insert.

The toughest materials go into every cutting tool and insert.

Both the cutting tool and insert is made of high-quality, wear-resistant micrograin ‘carbide,’ which is a chemical compound made up of carbon and a metal (or metals). Examples of carbide include chromium carbide, tungsten carbide, titanium carbide, and tantalum carbide

Carbide Cutting Tool and Insert Introduction

A carbide insert is made from two elements – carbide and cobalt. The carbide is granular and come in different sizes for specific cutting needs. The cobalt bonds the carbide grains. These two elements are combined in a range of ratios, sintered, and molded into the shape of an insert.

A cutting tool is not complete without an insert. A carbide tool is very hard relative to most to work pieces, so it is important to have a rigid tool holder and carbide insert so as not to cause ‘tearing effect.’ The combination of a carbide cutting tool and insert makes possible the machining of hard surfaces accurately into a final shape at an affordable cost per part – typically just 3 percent of total machining costs.
