JOBBER LENGTH: 3/16-inch cutting diameter, 2-5/16-inch flute length, 3-1/2-inch overall length, 135 degree split point, 3-flat shank
MADE FROM HIGH-SPEED STEEL AND 5% COBALT: improve much higher heat resistance because of cobalt steel's high red hardness, provide strong durable performance compared to typical hss drill bits
CAN BE REPEATEDLY SHARPENED AS NEEDED: cobalt drill bit's hardness is uniform throughout the entire material, so that can be repeatedly sharpened without damaging the cutting edge allowing it to drill more than hss drill bits
APPLICATION: best used for drilling in hard metal, including stainless steel
