Heavy Duty Surface Treated 135degree split point Screw Machine length
Heavy-duty 135degree split point. A short, sturdy drill bit.
A 135degree point is for metal. 118degree point is better suited for softer materials like wood.
A split point reduces the bit from walking or wandering when you are starting the hole.
A screw machine length is shorter than a jobber length bit. This makes the bit just a little stiffer for a rounder, straighter hole.
