Heavy-duty screw machine drill bits have a split point design and are shorter in length to provide rigidity and minimize deflection. High-performance carbide drills have a high penetration rate to create rounder, straighter holes. And parabolic drill bits have a large flute space for deep-hole drilling. Find fractional drill sizes and wire size drills with drill angle points from 118 degrees to 150 degrees, and a drill bit set containing up to 60 bits.
