Curfe and swarf are both related to the process of drilling into steel or other materials. Curfe, also known as “crown radius”, refers to the radius of the curved surface at the top of a drill bit. It helps to distribute cutting forces evenly and reduce the likelihood of the bit breaking or becoming damaged.
On the other hand, swarf is the leftover debris created when drilling a hole in steel or other materials. It typically consists of small chips of metal that are created as the drill bit cuts into the material. The swarf is usually removed from the hole as the drilling process continues and can be collected for disposal or recycling.
Curfe and swarf are related in that curfe is a property of the drill bit that affects the amount of swarf produced during drilling. A drill bit with a smaller crown radius will produce less swarf as it will cut more precisely, but will also be more likely to break or become damaged. A drill bit with a larger crown radius will produce more swarf but will be more durable.
In summary, Curfe is a feature of the drill bit that affects the way it cuts, and swarf is the end result of the drilling process, the debris or left over material.
