A: Hello! This bit is ideal for applications in metal, wood, and PVC.
A: 1.You need to clarify the tool you are planning to use this with. These bits were designed to be used in a 1/4" hex drive impact driver tool.they are not designed to be used with an impact gun. the will not holdup to the abuse of an regular impact gun. 1/4" Hex Shank. Use in Drills or Impact Drivers ,says nothing about being ok to use these with an impact gun. There is a big difference in torque and power in impact driver vs impact gun.
A: Hi John- This bit features a 135 degree split point tip to deliver a precision start and to prevent walking for fast, accurate holes in Hard Metal, PVC and wood.
A: It is 135, it is what they call a quad edge. I use these because the quad edge makes it easy to get the bit centered and started accurately. They cut exceptionally well. I have since purchased a full set of these bits.
