What is a step drill? A step drill, also known as stepped drill bit, step drill bit or step bit, is used for drilling a hole or enlarging an existing hole in thin sheet metal. Not only drilling, a step drill also can chamfer and deburr the cutting edge of workpiece by using the bevel of the next step.
A hole saw or hole cutter consist of steel cylinder mounted on anarbor and construction with power drills to cuta circular hole through a workpiece.Most hole saws have fairly short aspectratio of diameter to depth and they areused to cut through relatively thin workpieces .
Since an annular cutter removes only the material at the periphery of the hole, it is 3 to 4 times faster than twist drill bit. Besides, an annular cutter with pilot pin can finish a hole by one operation without pre-drilling for a pilot hole.
Drill tap is a combination of drill and tap to drill, tap and chamfer a through hole in one quick step. You can create many common screw holes for machine screws and bolts by inserting the drill tap into impact driver without switching cutting tools which really saves lots of time and money.
