Accusize 1/2" x 1/2" x 6" M35 Cobalt Square Lathe Tool Bit

I Purchased this 1/2 x 1/2 x 6 HSS with cobalt as it was the go to when making a carbide tool would be more time consuming or costly. I hand ground the tool until I had a 40 degree angle point as I have been doing for 40+ years, then finished with a diamond hone. Once in place, it cut a Poly-V groove into the 5" dia. 6061 T6 alum like butter- Keep the cutting oil flowing too! Choosing the 6 inch tool bit insured it would be held more securely in the tool post holder. 5 stars.

This is what I use to 'file' my natural Saxophone reeds with - for Consistentcy! (yeah, it's a thing). It has small burs on each edge. That edge, when used lightly, shaves the reed. The reed's edges should be tapered to a consistent wings shape while the center 'v' shape is thicker. There is a quality commercial steel tool available for this that has specific edges to use and there is another small file that comes with a textured piece of glass for filling the backs flat. But for me, this piece of stainless steel is cost effective, works well and will last for ever. It's normally used with a CNC machine, but it works for filing Sax reeds too! That makes it perfect for this task!

Fast shipping. great product, cobalt additive improves the cutting edge wear time.

Ok

Very good cutter. I was having dificulty on a project that required the facing and drilliinng of an inductioned hardened steel part. I coulld cut the non hardned portion with my regular cutting tools, but when I got to the harrdened portion, it wouuld wipe out my cuttinng insert. After going through several cuttinng inserts, I ordered this cuting bar. I put a profile on it with a grinding wheel, and was able to finish facing my parts. However, I had to go back to my grinder several times to put a new edge on the cuter before finishing the two pieces. BUTT - that is the benifit of using this type of cutter - you can resharpen it, and with it's length, you can do this many, many times. I am still trying to find drill bits to perform the drillinng portion of my work, and have found no solution yet (M42 colbalt biits are not workng). (Just for info - the parts are stub axles, cut off of CV axle shafts for a Toyota Tacoma 4x4)

just as ordered

Great steel for making wood turning tools using carbide cutters!

Just ground one of these into a RH tool and turned the rusty crust off of a 1.5" diameter mystery-metal steel shaft. Edge held up well. Grinds and hones well. Seems to be high quality, at least for a hobbiest.

The tool steel blanks come nicely protected in their own individual sleeves. I ordered the 3/8" (9.525mm) by 5" variant. Four of the five blanks looked more or less perfect, with a clean ground finish. It's difficult to photograph, but one blank had some strange buffed or polished finish at the ends, which measured undersize (9.474mm). The blank still measured true in the center. You can see the odd finish in the attached photos (if you're viewing on desktop, right-click the image and select "View Image In New Tab" to view the full-resolution image). This defect likely doesn't matter very much as you're probably going to be grinding the ends anyway. Aside from the one issue, the blanks seem to be pretty decent quality.

The product was exactly as described and good quality.

These are a pretty good deal, at roughly $4 per blank. The size is just a little bit undersized in both dimensions, about a thou in diameter, and a few thou in length. The blanks are individually packaged, and my batch looks pretty uniform. The M35 steel retains edge well when hot, so these are perfect for tool making. Recommended!

Worked as it should

holds an edge good when cutting aluminum but so does an old butter knife.
