Core Drills vs. Conventional Twist Drill

What drill fits your work process the most? Today, we’re going to compare two drills to know which one is more efficient and saves you a lot of time.

Conventional Drills

·         It only has one cutting edge or point.

·         Since it is solid, it has only cutting point and has to be cut or remove the complete material of the hole to be made.

·         Takes more time drilling a hole

·         requires pre-drilling or step-drilling

·         Can be messy when drilling

Core Drills

·         Have multiple cutting edges that can help in drilling with less horsepower and efforts.

·         Since it has multiple edges, hollow cuts only on the periphery of the hole can be made.

·         Cut less materials and the time it requires is less

·         Considered to be 3-4 times faster

·         Single core drills can make 5 – 10 times more holes

·         Can be re-grounded to make another 1500 holes meaning it saves you a lot of tool costs

·         Even on larger diameters, it does not require any pre-drilling or step-drilling

·         It provides better accuracy

·         Burr-free holes and smooth holes created

The advantages of the core drill are listed here but there are also disadvantages like, it cannot drill on blind holes. The reason behind this is that with the hollow geometry, it can only make holes through. Another disadvantage of the drill is in drilling piles of plates. However, there are certain kinds or brands that are able to cut through drilling piles, but it doesn’t guarantee 100% success rate. When it comes to the price, it can be more expensive than conventional drill but more efficient.
