Fisch Black Shark Forstner Bit Set 16-piece

Fisch Black Shark Forstner bits are forged, and CNC machined for durability and precision. They use the same wavy edge as the “Wave Cutter” bits they replace. Black Shark bits cut accurate, splinter-free holes in soft and hard woods at a higher drilling speed while reducing heat to prolong tool life. They excel at drilling edges or slanted holes. Like all Forstner bits, they cut clean, flat-bottomed holes in hard and soft woods.  The premium tool steel in Black Shark bits will cut more than 3.5 times as many holes as standard Forstner bits, and it can be sharpened up to 30 times.  The shank is round with three flats for excellent grip in all chucks.  Inch bit shank size - bits up to 1/2" have 1/4" shank, 5/8" bits have 5/16" shank, bits 3/4" and larger have 3/8" shank Overall length -~3-1/2"
