High Speed Steel Cutting Tools Operate At Cutting Speeds

Recommended cutting speeds using high speed steel tools.

High speed steel cutting tools operate at cutting speeds.

Under equally suitable applications a carbide tool can cut 4 to 12 times faster than hss depending on work material and type of operation and naturally the productivity is proportionally high. High speed steel hss or hs is a subset of tool steels commonly used as cutting tool material. For reamers use 1 2 to 2 3 speed given in this table. Cutting speed 50 fpm.

As already mentioned hss can in no way compete with carbide tools when it comes to cutting speeds. A 1 00 inch high speed steel hss drill is being used on a piece of 1045 steel with a brinnel hardness of 300. All cutting tools have a recommended cutting speed for any given material. It is often used in power saw blades and drill bits it is superior to the older high carbon steel tools used extensively through the 1940s in that it can withstand higher temperatures without losing its temper hardness this property allows hss to cut faster than high carbon steel hence the name.

For carbide tools double the speeds. So too can carbide and ceramic cutting tools achieve higher speeds regardless of the workpiece material than do ones made of high speed. Calculate the rpm setting to perform this cutting operation.
