Faster cycle times and higher accuracy.
TRI-Cooling is optimal for small-diameter drills and can achieve more than double the conventional coolant discharge volume. This can dramatically improve chip discharge and heat dissipation, contributing greatly to tool life stability.
Increased coolant flow provides effective cooling even in difficult applications or when using an oil based cutting fluid.
The straight cutting edge and thinned point are connected with a smoothly curved geometry that significantly improves fracture resistance. The geometry of the rake angles and lands also improves wear and chip disposal.
The new point thinning breaks chips into the optimum shape for streamlined flow and achieves a much lower cutting resistance.
The short drill is designed for high rigidity and good chip evacuation by minimizing the neck length.
A chip discharge area is provided over the taper part, increasing the tool rigidity by 20% more than the conventional model as well as improving the hole position accuracy.

For deep holes it is recommended to use a pilot drill to improve hole entry and reduce deviation at the exit point.
DP1120 is applied a special multi-layer PVD coating and a micro-grain, cemented carbide substrate. The outstanding surface smoothness prevents chip clogging that reduces breakage.
Additionally the excellent abrasion resistance maintains cutting edge sharpness to enable long
DVAS has excellent fracture resistance and double tool life compared to conventional products.
It achieves excellent welding resistance and chip control for drilling stainless steels.
The hole bends are significantly reduced as compared to conventional products.
