Four Different Qualities of Core Drill Bits
Quality affects the life of the bit more than the drilling speed.
We can NOT quote how many holes a bit lasts due to the large number of variables, thickness of material, hardness of material, etc. The better the quality - the more holes it drills. Also note there is a very poor quality bit being made and sold on the internet. The fourth quality - we do not sell it any more and would warn you about it.

Diamond
Glass Drill Bits -
A higher quality than the above bits. These Sintered
have exposed diamond in a metal matrix around the rim. This means
that they last much, much longer than the above electroplated
bits. Longer lasting does not mean faster drilling. All qualities
drill about the same speed. Great for glass, marble, tile or
stone. 30 mm (over 1") core depth. The larger 1/2"
shaft requires a large drill chuck. Wall thickness is .10| Order # | Size-Diameter | Price |
