Micro 100 Carbide Drill Mill for Machinists

The Micro 100 DM-500-490X is a carbide drill mill with a 1/2 inch milling diameter and a 90 degree point angle. It features four flutes and an AlTiN coating for extended tool life. Machinists use it for drilling, milling, and chamfering operations in a variety of materials.

Four-Flute AlTiN Coating Improves Wear Resistance

The AlTiN coating increases surface hardness and reduces friction during high-speed cutting. Four flutes provide improved chip evacuation and a finer finish compared to two-flute designs. This tool is not suited for applications requiring a different point angle or non-ferrous materials where uncoated carbide performs better.

Questions about this item

When will the AlTiN coating on the DM-500-490X need replacement?

The AlTiN coating wears gradually during cutting; plan to replace the tool once flank wear reaches the limit for your tolerance.

What limits sustained use of the 90-degree carbide drill mill first?

Heat buildup at the cutting edges typically limits continuous operation before the carbide substrate is affected.
