Hello everyone.

I have few dull drill bits for porcelain stoneware and tiles. The drill bits have a triangular shape. An example is shown in the image.

You cannot view this attachment.

Does anyone have experience sharpening such drill bits on a Tormek?
I think it will needs, for this type of metal, diamond wheels.
But how exactly? Which jig or device should be used? DBS-22? MB 100/102? SVD-110? Or something else?
I would be grateful for a reply from anyone who has this kind of experience.

I haven't tried yet, but maybe it's possible to setup the MFB in such a way that you could somehow use the truing tool on the side, at least between the outer edge and a minimum radius ?

here is showed as possible to use truing tool on flat side

FYI

I have checked the factorys sharpening Spyderco Military 2 (CPM S110V) - 166, 175, 156 BESS in different parts of the blade.
Angle 16/18 dps.
Total angle is 34 degrees.

This factory's result looks as mine on Tormek standart kit))))

I agree. I guess it will be difficult to get lower BESS on this set (SG+honing weel)
I tried to play with the honing angles (probably on hands, not at fixed angle), but be honest, I didn't see a difference.
I think that the SG stone + leather wheel with Tormek paste giving just like my results.
And for lower BESS rates need to use felts, wool, diamond sprays, etc.

Thank you all for your comments - if anything in my process will change - I will let you know.

Thank you Ken,

I saw this video, and my results still around 150 bess. I guess the reason of this my angle on bevel  - it is depends from knive, and usually is 13-15 degrees on bevel.

May by I will try to do 10 degrees for the experiment, and it will takes low pressure on BESS, but also want to achieve a higher sharpness without lowering the sharpening angle.

Hi everyone.
I've sharpening my knives last year, and I can't understand how people achieve 50-60 bess?
My knives has around 150 bess - this is my best result. Usually 160-170 bess.
I using a standard SG stone and a leather wheel - standard set. May be for this set 150 bess is maximum what I can get?
Totally, for usual use, this sharpness is completely sufficient, but how do people manage to achieve less than 100 bess?

I had the same situation with my T8 black. New DF-250 from the box had damages, some deep grooves on stone.
After contact to seller, during few days, they changed the stone for the new.

I'm curious as the owner of 3 T-8's and a T-2 why water isn't used with the T2 wheels? I thought the purpose of water cooling on the T-8's was to keep the knife edge cool at the point of contact. Am I wrong here? Although the T2 rotates at a much slower speed there seems there would be sufficient heat buildup at the edge to affect the properties of the knife.  Am I wrong?

Did I understand correctly from this video - it is not necessary to use water for diamond wheels on the T-8?
