Perfect for home shop hero
Item Package Quantity: 5 Size: 3/8 in
I use speed tiger endmills on my Bridgeport every day. They are verysharp and stay sharp for a long time. cut gummy 1018 steel like butter dry. sharp enough to cut aluminum. Work great on stainless and tool steel. Surface finish on facing is always close to mirror. edge is fine for machine parts but would need to polish for ornate parts. If you are breaking these things. Lock the x when cutting x and lock the x when cutting y. Don't make heavy climb cuts without drag on the current axis lock. ... show more

Quality end mills, good price

Despite the small size, was able to mill 5/16" deep slots in cast iron with ease and without breakage.

Not bad at all
Item Package Quantity: 5 Size: 1/4 in
These bits are definitely beyond my expectations. I have been cutting .125" depth at about 18ipm and the chips are flying. About 10 parts cut so far and still going. Getting ready to pull the trigger on some 1/2 and 3/8's as well

Way better than expected for the price

Ate through the inch of aluminum I needed it too so mission accomplished. Did good at drilling two critical holes as well and I honestly couldn't ask for better performance.
