Diamond Electroform Glass Core Drill, 2 1/4” Diameter, New/Other/Second: This core drill was made in either the USA or in England. It has never been used, but was sold to us as a second and we don’t know if this was due to an overstock, a style change, cosmetics or it didn’t pass quality control. We have sold many of these to customers and have not received any negative feedback. The kerf on this “glass drill” is thin. It measures .023” in thickness. The diamond is very fine and provides outstandingly smooth drilled holes in glass. The electroform diamond is industrially made for for strength and durability.  The shank is 3/8” diameter with a coolant hole through its middle. There are 2 round holes on the top of the core drill to let coolant and sludge to escape. The use of coolant is necessary. You can use either a water chuck or an external water source. This drill is sold with the Kent’s Tools 30 Day Satisfaction Guarantee.

Shipping note: if you buy two pieces, either the same or a mixed pair of this item and the other one we have for sale that is 2" in diameter, shipping cost will be the same as one item.
