Frequently Asked Questions
What are center drills used for?
Center drills are used to create a precise, small-diameter pilot hole followed by a larger countersunk hole. This allows a workpiece to be mounted safely between lathe centers or on a grinding machine, ensuring accurate rotation and uniform machining of cylindrical parts.
How do I select the correct center drill size?
Choose a center drill based on the size of your workpiece and the capacity of your machine. The shank must fit your chuck or collet, and the pilot diameter should be appropriate for starting the hole. For larger workpieces, use a larger center drill to provide sufficient support and stability.
Can these center drills be used on stainless steel?
Yes, these high-speed steel center drills are suitable for drilling stainless steel and other common marine alloys. To achieve best results, use a suitable cutting fluid to reduce friction and heat, which helps prevent work hardening and extends tool lifespan.
