Drill Bits for Precise Holes in Wood

Uncoated High-Speed Steel
Three sharp points allow these bits to drill accurate straight and overlapping holes, even across the grain. The center guide point prevents the bit from wandering. Also known as brad-point bits.
High-speed steel drill bits are stronger and more wear resistant than steel drill bits.
