Great for glassware

[This review was collected as part of a promotion.] It helps me pierce glass when creating water glassware devices. Next ill move on to a thicker diameter diamond accesory.

Great Diamond Point For Etching

[This review was collected as part of a promotion.] The 7144 has a great little point that can be used sideways to do a wider etch or use it's point for fine lines. It is a very good shape and size for smoothing the entry edge of small screw holes, relieving edges of other hard materials.
