2. Size and Shape

The size and shape of the drill bit are also crucial factors to consider. The drill bit should be the appropriate size for the hole you need to create in the sink. It’s important to measure and mark the desired hole size accurately before selecting a drill bit. Additionally, the shape of the drill bit’s tip should be considered. A sharp, pointed tip is generally more effective for drilling through stainless steel while minimizing the risk of slipping or damaging the sink’s surface.

3. Coating

Coating on the drill bit can also affect its performance when drilling through stainless steel. Some drill bits come with a special coating, such as black oxide or titanium nitride, which can help reduce friction and heat buildup during drilling. This coating can prolong the life of the drill bit and improve drilling speed and efficiency.

4. Shank Type

The shank type of the drill bit is another factor to consider. The shank is the part of the drill bit that fits into the drill’s chuck. For drilling through stainless steel, a drill bit with a 3-flat shank or a hex shank is often recommended. These types of shanks provide a secure grip and prevent slipping or wobbling during the drilling process.
