A HSS Co Cobalt 90 degree spotting drill for use with various machinery.
These drills have replaced the common center drill for marking holes prior to drilling.
These drills are designed to be extremely rigid so that they can precisely spot a hole for a twist drill.
Maximum meat in the shank keeps them on target.
The goal is to use the spot drill to make a little dimple in the workpiece that keeps the twist drill from walking so that the hole winds up in the right place.
While center drills are available more cheaply than spot drills, they have some disadvantages.
The small pilot tip is very delicate for example, and if it breaks, the drill will quit cutting. Not a happy thing if you’re running a job that involves spotting a lot of holes.
Another problem is the hole angle of a center drill is typically 60 degrees. When spotting, you want an angle that is larger than the twist drill’s angle if possible.
1x Spot drill is supplied please see our other items for different sizes of spot drills and the traditional center drills if you prefer.
