Spotting produces a shallow hole to get better hole position enabling to produce more accurate final product. Ideally, the proper spotting angle should have larger point angle than that of your drill, so the center of a drill shall be the first point to contact workpiece to avoid the drill walked or moved in starting drilling.
Nine9 spotting tool is not only produce better hole position allowing the drill to machine in higher feed rate, extend tool life of drill and improve production efficiency, it also ensure geometrically uniform holes to stabilize products quality.
Nowadays, to cope with market demands, we supply various point angles.

ACE Spot Drill possesses precise positioning of the insert derived from dual clamping screwed design ensures the vibration free while cutting, plus symmetric 2-flute edge design reducing the lateral force, it enhances ACE Spot drill rigidity enabling to run high feed rate. Furthermore, the double point angles make the insert tip stronger to prolong service life, which results in lower production costs. Optimal internal coolant design brings better balancing to run at high speed.
