I used it at high speed on my TR Crush shafts and it cut through like butter and left a very clean cut. Just touched them up on ASD and they are great.They'll splinter. I made an arrow saw using a Dremel for the motor and use small cutoff wheels. I revv 'er up to about 12-15000rpm and it cuts through like nothing.
Had one and hated it. It would leave a little carbon skin around the edge and sometimes cause a very small splinter. I bought a $85 8000 rpm Weston saw from Bowhunters Super Store that works like the shop saws. I highly recommend skipping that HF junk.
I have this and I get splintered ends. what I do is I wrap the part where I cut with masking tape. the tape helps reduce splinters; you'll get a clean cut.
