HHIP 2000-0005 3/8 x 3 Inch M2 HSS Square Tool Bit

Looks like a good piece but haven’t used it yet

Seam to bb a good value.

works great and put out lots of sparks

I got this to make a wood-turning tool called a bedan. Last year I made one out of M2, and I wanted to try M35 to see if it would hold an edge longer. M35 is basically M2 which has cobalt added to improve the wear-resistance and red-hardness. The downside of wear-resistance, of course, is that it takes a lot longer to grind, but a bedan is a pretty simple tool to make, and the red-hardness means you can do most of the grinding on a bench grinder or other high-speed grinder without affecting the hardness. The thing I wasn't prepared for was that the blank had scratches on all four sides and the sides weren't perfectly flat, and, for mainly esthetic reasons, I give my tools all my tools' flat surfaces a high polish with a series of diamond sharpening stones. This has to be done by hand, and in this case it took forever.

Not much to them. They’re round, straight, and made of steel.

I used a 3/16" tool bit to make a broaching tool to cut keyways in gears. After over a dozen keyways the tool is as sharp as when I first ground it.

Proof is in the pudding but I liked the way I ground them down to shape. Will see how they hold up on the lathe

Grinding one end to a parting tool takes quite a bit of time compared to standard steels that I normally grind for other things. This should perform nicely when I get it all finishe.d

I'm using these (I bought 2) on my mini lathe. needed to custom grind/shape for a specific use that you just cant do with inserts or carbide tipped tooling. These HSS blanks seem to be of some quality and will buy more when needed

Good quality for the price!

Bon outil ca fait la job.

Too expensive
