Hello lapidary blade makers,
My unknown brand (some blue paint left on one side) 18" notched rim blade needs to be "sharpened/unglazed" after cutting maybe 20" of Kentucky Agate. I hear quality sintered rim blades such as MK303 do not need to be unglazed. Does MK303's segmentation of the rim require some de-glazing when cutting agate? Does MK301 notched blade need de-glazing or do the diamond characteristics/packing avoid that need totally?
Thank you,
Al

You can utilize a dressing stone to see if that will dress open the blade (a few 1/8 inch cuts in a hard brick will suffice as well). However, depending on how old this blade is it might be at the end of the useful life. We recommend that if you want to get a very good cutting blade that you should look into the 303 and use a dressing stone if when you note the performance dropping off. This type of stone is very hard and the blade requires additional care to ensure that it will continue to cut.

Hi Blademakers,
I have purchased a new 18" 303 (segmented rim). Is there a break in period? Or can I simply start cutting hardest agates immediately?
Thank you,
Al

Al,

Actually, it's best to go right to the material you're going to be cutting as blades tend to glaze differently for each material. If you're going to be cutting several different agates, try to cut one type all at once and redress before moving on. Start very slowly on each new material until you get a feel for the blade speed with respect to the individual agate.

Hello,
Can I use a MK-100 for Lapidary work? Any info would help. Thank you, Fordo

Fordo,

Provided that you are meeting the length, diagonal and depth of cutting capabilities provided by the saw, the MK-100 is an excellent tool for this application. The critical element in the whole equation is getting the correct blade for the type of material being cut. You can find a list of MK's lapidary blades at:

We are a rock shop in Cottonwood, Az, buy our blades through Kingsley. A frequent query from customers is whether a MK Diamond BD-301 Supreme Rim Blade can be rehabilitated once it becomes badly "dished", but still has lots of visible diamond. Do you provide such a service or know if someone else does?

Hello, I purchased a MK-303 to cut 3/8" thick art glass. See website. Upon receiving the blade I found out that I need to use a cutting oil with it. I usually use antifreeze and water. What diamond blade do you have that I can use to cut glass and uses water or antifreeze as a coolant?
