Brazed Carbide vs. High Speed Steel -Inserts Rule But- What's Better When You Don't Have An Insert?

Head to Head comparison cutting of a Brazed Carbide tool and a High Speed Steel (HSS) tool in 3 different materials. High resolution pics of the finish in 7075 Aluminum, Annealed 4140 and 316 Stainless to see what cut better. I use inserts 95% of the time, but when you don't have an insert for the job and want to know what is the better option between Brazed Carbide and HSS. Because buying a specialty insert and tool holder for every special job is not always cost effective.

Whether you are new to machining or an expert, if you want to know which tooling will work better to fill the gaps in your Carbide Insert tooling, or if you don't use Carbide Insert tooling, this would be a good video to explore.

This video discusses very high level about tool grinding angles (relief angle), and also shares some information from the Machinery's Hand Book 23rd Edition about the difference between Brazed Carbide and HSS tooling.

Spoiler alert, I went into this thinking Brazed Carbide tooling is better than HSS and in my mind this video proves that.

You can check out my channel for a video about sharpening Brazed Carbide tooling and also for a video about how to make a set of spacers to mount a Silicon Carbide grinding Wheel and a Diamond Cup grinding wheel together on your grinder.

Thanks for watching!

All machining is this video is done on a Precision Matthews PM 1440TL Lathe.
