Precision Twist QC21CO 19/64" Parab FL Drill 135dg Spl Pt Cobalt HSS 3 1/16" Flute 4 3/8" L Parabolic flute drill bits have a large flute space for greater chip flow and improved coolant flow to the drill bit point. These factors allow bits to drill deeper and produce closer hole tolerances more quickly than regular jobber bits. A large cross section increases rigidity and strength. Bits have a reduced margin width to lessen contact between the bit and the hole sides to minimize friction and heat. A self centering 135 degree split point penetrates faster than other point styles, produces smaller chips for better chip flow, and will not skip or walk when starting a hole. The shank diameter is the same as the drill bit size. Cobalt steel material.
