12-piece carbide masonry drill bit set

This Olympia Tools set contains twelve carbide-tipped bits covering seven diameters from 1/8 inch to 1/2 inch. It is aimed at DIYers and tradespeople who need a single kit for brick, tile, concrete, wood and plastic. The triangle shank fits standard electric, hand and bench drills for quick changes on site.

U-type slot limits debris clearance speed

The U-shaped flute evacuates dust while you drill, but evacuation rate drops in deep holes or very hard aggregate. The supplier notes that water should be added when cutting harder materials to keep the tip cool and maintain cutting speed. Dry drilling is only advised for softer substrates such as brick or plastic.

Not compatible with hammer-drill impact mode

The bits are built for rotary drilling only and must not be used in a hammer drill with the impact function engaged. Buyers who need percussion drilling for reinforced concrete or heavy masonry will need a different shank design rated for hammer action.

Questions about this item

Which drill bit sizes come in the 12-piece set and how many of each?

The set includes one 1/8", one 5/32", two 3/16", four 1/4", two 5/16", one 3/8" and one 1/2" bit.

What does the carbide tip do when drilling into concrete or tile?

The industrial-grade carbide tip resists wear and cuts cleanly through concrete, brick, ceramic tile, glass and marble without dulling quickly.

How does the triangle shank and U-type slot affect drilling performance?

The non-slip triangle shank locks securely in electric, hand or bench drills, while the U-type slot clears debris fast for smoother holes.
