Automatic Center Punch Set, 2 Pack 6 & 5 Automatic Centre Hole Punch, Super Strong Adjustable Impact Center Hole Punch Tool, Marker Scribe Spring Loaded Punch Tool for Glass Metal or Wood

Great compact solution to marking for drilling or layout plans on multiple surfaces.

Stay away, The hammer mechanism in these low cost punches does not work often.

Larger of the two punches stopped working the day after the return window. Cheap built and not much of a punch even when it works.

Only use it a few times before the tips got no and one of the springs I had to change out already in the big one my opinion not worth the money

Both the punches are weak. Will work good for wood, but not on metal. Multiple attempts and barely a point in a broken off bolt.

Good product and well made.

very good product...

Too cheaply built.

the larger one requires considerable force but leaves no visible mark on mild steel.

great for woodworking also
