Topic tags/keywords: wood bit lubricant

I am making a series of Roorkhee chairs from hard maple which use a conical mortise hole which I am cutting with a three-flute reamer in a milling machine. The reamer cuts just fine but produces a high-pitch scream, even at low rpm. I am curious as to whether anyone has found a lubricant which might reduce that noise and yet not interfere with the final application of a finish.

With no idea whether this would work, you might try beeswax. I use it as a wood screw lubricant in hardwoods, and haven’t had any problem with the finish. Might be worth giving a test drive.

I’ve tried oil and wax to some benefit but it doesn’t stop the squeaking entirely. When drilling on the lathe I wear ear muffs.

Bostik DriCote would probably work for you.

Bill, I am using a vertical milling machine, turning about 350 rpm. The three flute spiral and tapered reamer is hollow ground but with an 1/8 inch flat trailing the cutting edge by about 3/16 inch. I don’t know to how many thousands the flat is relieved from the cutting edge but have assumed that the trailing flat is the noisemaker. Ken

Thanks to all those who have responded. Looks like Drikote might be the solution.

BTW, this really helps when you have to use a template with a hand drill for drilling large holes, such as 3/4in dog holes, It really saves the day.

Quite literally, I would spray the bit ever other hole and things went at least twice as fast or more. I could have sprayed every time but I was being conservative. Later on, I realized that that would have actually saved me additional time and effort. I balked at the ~$20 cost at WC, but later found better deals online and for 3-paks and such. Well worth the effort to look for deals, IMO.

Do note that the can has changed it’s looks.
