View Full Version : AO Wheels for HF Grinder

The carbide grinder I ordered from HF arrived this week, complete with the green silicon carbide wheels. I've been searching the tool catalogs for metal backed a/o wheels for grinding HSS & T15 tools - so far, the only ones I've found are Norton wheels in MSC for $80 ea.

I assume metal backed wheels are the only type suitable for this grinder because of the mounting backplate, but the price seems a bit steep for someone who uses mostly indexable carbide tooling. I bought the grinder because I have a number of old HSS & brazed carbide tools, as well as a small supply of T15 blanks, and have found it somewhat awkward to freehand grind tools on a regular bench grinder. I'll keep one of the green wheels on it for the brazed carbide tools, and put an A/O on the other end. Would a 60 grit wheel be a good compromise for someone who plans to do more sharpening than grinding from scratch?

Also would like some advice on what type of dresser to buy. I can see the need for one before using the grinder, as there's a little more vibration than I'd like right out of the box, and I can see some loading of the one wheel I've used with HSS already.

Thanks for the help guys. I checked both sites you mentioned - it appears KBC has the Triumph wheels on sale for $18.10, which is considerably under the $80 MSC wants for Norton wheels. Will one of the inexpensive wheel-type dressers work OK for these & the SC wheels, or will I have to use a diamond dresser for the SC?

flatlander,

I could be full of it but I "thought" someone posted something about the Triumph wheels are not exactly 6" in diameter. Something like 6 1/4" instead and wouldn't fit on the HF grinder you purchased. Dunno, I could be WRONG but I'd check.
