The highest quality high-speed steel brad point drill bits are designed to stop the drill bit from wandering as you start your cut. They are also known to create less tear-out.
Great for marking a center point through a drilled hole onto another surface.
All sizes up to 10mm have a straight shank the same diameter as the drill bit.
Bits with a diameter over 10mm have a reduced 10mm shank.
Note - In an attempt to minimize unnecessary packaging, Stern uses a recyclable protective tube with a plastic barcode tab for smaller twist bits. Laser engraving, when too small to read, may also be omitted. That's normal.
