Your best bet is to use the carbide bits because they are the hardest drill bits available.Ĭarbide drill bits are used for drilling broken bolts, safes, studs, bearing races, taps, and knives made from hardened steel. If you've worked with hardened steel before, you'll know that a regular drill bit won't cut through. However, there are other options such as titanium and cobalt. They are the most suitable drill bits for hardened steel due to their robust and heat-resistant properties. Keep up this orbital motion until you finish drilling.If you are short on time, the best drill bits for hardened steel are carbide-tipped bits. This reduces the friction created while perforating and helps cool the drill bit with air.
Once you have the drill bit in a vertical position, you should rotate it in an orbital motion to help dust escape and to help air enter the hole where you’re drilling. Step Three: Use An Orbital Motion As You Drill The purpose of this is to help prevent the drill bit from sliding over the tile and out of your control. Once you’ve drilled a groove into the tile to help you keep your drill bit in place as you perforate, you can slowly start rotating the drill bit and moving it into a vertical position. When the drill bit is first making contact with the tile, hold it firm and steady and at 45 degrees against the tile’s surface.

Since the edges crack more easily, you should try placing the holes at the center of the tile. If you are drilling a hole for accessories such as a towel bar, you should use a level to ensure both holes are aligned.

To prepare an area for tile drilling, start by adhering masking tape to the portion of the floor or wall where you intend to drill.

Carbide is a known strong material that cuts through most hard elements that regular drills cannot get through. Ceramic tiles, on the other hand, whether for wall or floor use, have a glaze on top of the surface, giving its color and finish and preventing them from absorbing water.Ī carbide-tipped masonry bit is the best tile drill bit to use for drilling glazed ceramic tiles.
