HSS Step Drill Bits
To make a
precise desired hole for panel or switch on the metal sheet or any non-ferrous
materials for non-professionals, you may feel a pain to do so. To drill
different holes with standard drill bits on the sheet, they may come out at the
wrong place or wrong sizes, due to without drill stand or sliding up and down
the drill.
By using
step drill could solve some problems you may face above. Made of M2 high speed
steel, they are designed like a tower and each floor have different sizes, so a
piece of step drill can replace many standard one size drill. Besides
single-fluted step drill, a spiral-fluted step drill, which drill in a more
smooth way than single-fluted one and face less resistance against any drilling
work piece while drilling.
