Making a Center Punch From Scrap

Introduction: Making a Center Punch From Scrap


Hello Instructableles? Instructoids? Instructafarians? Whatever.

A simple and fast instructable on how to make a center punch from scrap material. In the video we're using the shank of a concrete drill, but it could be adapted to use any kind of hardened steel round scrap, such as the shank of drills and endmills.

Center punches are extremely useful tools when preparing to drill holes in both metal and wood alike. With a center punch and a hammer you tap a small divot in the material you want to drill, where you want to drill it, which helps to guide the drill to the exact location you want your hole to be in.


Material:

Hardened metal rod scrap
, such as from a concrete drill


Tools:

Angle grinder
, with cut off wheel
Bench grinder
Lathe with carbide tooling
(optional)

    If you have a slightly blunted version of this centre punch then it is useful for countersinking pop rivet holes (before the rivet is inserted) in sheet metal
