This article gives suggested feeds and speeds for drilling and reaming taken from the bssa stainless steel specialist course training note no9 machining stainless steels. Hardness up to rc 67. Hey work well with a variety of materials. Cutting speed 40 fpm diameter of cutter 0 3701 g drill half the speed for reaming would be 432 2 216 rpm for reaming.

High speed steel chucking reamers provide good wear resistance in a wide range of reaming applications. A high speed steel g drill is being used prior to reaming a 3 8 hole on a piece of 1095 steel with a brinnel hardness of 300. High speed steel hss reamers are an excellent choice for low cost production jobs. Click here to find the right drill size for you reamer.

High speed steel offers good wear resistance has some flexibility and can absorb some shock and vibration. Chucking reamers sometimes called machine reamers enlarge or finish an existing hole to an exact tolerance or size for. High speed steels most commonly used. The high cobalt versions are very resistant to heat and thus excellent for reaming abrasive and or work hardening materials such as titanium and stainless steel.

Sharp cutting edges meaning less cutting force. Speed equals 80 surface feet per minute in 100 brinell hardness material and the speed should be reduced 10 surface feet per minute for each additional 50 points brinell hardness. Alcrn is harder resists cracking and oxidization better and performs better in high feed applications than tialn. Tialn withstands high temperatures.

Traditionally high speed steel hss tools have been used for drilling and reaming but carbide tipped tools are also used for specialised jobs or long production runs. These general purpose reamers have a straight shank that mounts to the chuck of a drill press or similar machining tool.
