   No, they should be made of high speed steel. All quenching might accomplish is breaking the thing because of the temperature change shock.

   Check to see that the bit and chisel are properly sharpened. Even on a new unit this may be required. Check the instructions that came with the unit. The space between the chisel end and bit is critical.Too much space allows chips to be too large,and this will cause heating.Install the chisel and clamp it down.Now insert the bit until it just touches the inside of the chisel.Rotate the bit by hand to check clearence.Now drop the bit slightly to get minimum clearence.On my unit, a slight noise is normal.FWIW ¬¬¬¬¬¬¬¬¬¬¬¬¬PAT¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬

   Pat, another method for setting the correct space, but I'll agree that setting the bit too close or too far can cause burning problems. Install the chisel. Put a quarter, 10 pence piece, or other slim coin on top of the shoulder of the chisel as you slide it up into the sleeve. Trap the coin tight between the shoulder of the chisel and the sleeve. Lock the chisel in place. Shove the bit up 'until it bottoms out on the internal fluting of the chisel. Lock it in place. Slacken the locking mechanism holding the chisel. Remove the coin. Push the shoulder of the chisel up tight to the bottom of the sleeve, square it to the back fence, and lock it tight. Et, voila, perfect gap between bit and the inside of the chisel with no guess work. Slainte, RJ. http://www.RichardJonesFurniture.com

   Sgian, you're gonna have to give us a hint about your name, and the mystery as to what it means if you are really Richard... ;)

   What's your prefference on chisels and sharpening?

   I'm all ears, again.

   Thanks,

   mike.

   It's just a handle and translates literally as 'Knife Black' from the Gaelic. Slainte, RJ.http://www.RichardJonesFurniture.com

   FWW Issue 156 page 55 has a full description of the technique you've described. Matter of fact there is a whole article on the subject of mortising chisels. I've tried it and it definitly makes a difference.

   Every now and then I'll use a little beeswax to lubricate and i guess it cools some too. Got one of those adjustable compressed air nozzle gizmos to blow away chips and it does help cool the chisel and bit . Sharpness is for sure a factor too. Bit really should not smoke, bad for bit and chisel. Good luck

   Cool! ;)

   I also have a thread on mortise chisel sharpening - May I ask what chisels you use and your sharpening technique?  I took a quick look at the Clico bits and sharpening sys, it looks good.  Until then I'm going to try a ball shaped abrasive stone.

   Thanks!
