The 7 Best Glass Drill Bits

Sold in a tasteful silver case, the Brackit 6-Piece is one of the least expensive sets in a category replete with entirely affordable products. These spade-tipped pieces do not, unfortunately, feature the gripping function that makes the best of their kind so popular.

For those needing more fine-tuning instruments in their job, hobby, or craft, the SE Diamond Burrs are an excellent, inexpensive option to look into. These pieces come in a variety of shapes, including cones, balls, cylinders, and others.

The Neiko Diamond Grit is both an excellent option on merits alone and a great value when considering the price. This five-piece set of hole saw pieces will cut smoother, cleaner holes than the typical spear bit, so long as the driller moves slowly and carefully.

This spade-headed ensemble from one of the biggest names in power tools, the Bosch GT2000, is a set of four carbide-tipped pieces also recommended for use on some tiles. Their tips make it easier to begin a groove in the precise location of the soon-to-be hole.

The so-called Blendx Diamond is actually tipped with something known as silicon carbide, a substance a shade softer than diamond. Marketing hyperbole aside, this set of ten steel composite hole saw pieces will handle jobs needing a delicate touch easily.

One of the many sets of diamond-tipped hole saws out there, the Drillpro 15 Piece is notable as one of the largest of such on the market. More pieces means a greater variety of sizes of circles can be drilled, and that versatility lends this set to a range of uses.

The Bosch GT3000 is the tool company's expanded spear-headed kit, giving purchasers four more pieces than the previous iteration. Most of these new bits are larger than anything in the prior generation, while the small ones drill smaller than the narrowest hole saw.
