Micro 100 DM-125-290 Carbide Drill Mill

The Micro 100 DM-125-290 is a carbide drill mill with a 90-degree point angle and uncoated finish. It is intended for machinists and fabricators who need a single tool for drilling and milling operations. The two-flute design supports chip evacuation in a variety of materials. This item ships directly from the supplier.

Replaces separate drill and end mill tools

Combining drilling and milling in one tool reduces tool changes and setup time. The jump is worth it when a job requires both holemaking and slotting with the same 1/8 inch diameter. Uncoated carbide performs well in non-ferrous and low-alloy materials where coatings add no benefit. It is not for high-volume production runs that demand coated tool life.

1/8 inch diameter with 90-degree point

The 1/8 inch milling diameter handles small-hole drilling, chamfering and light profiling in softer metals and plastics. Carbide hardness provides wear resistance beyond high-speed steel in abrasive composites. Headroom runs out in hardened steels or deep cavities where coolant-through or coated geometries are required. It is not for heavy roughing or high-feed milling strategies.

Questions about this item

What shank diameter does the DM-125-290 need to fit my tool holder?

The carbide drill mill has a 1/8 in milling diameter, which matches the shank size required for standard 1/8 in collets or holders.

How do I install the DM-125-290 in a collet without damaging the 90 degree point?

Insert the shank fully into the collet before tightening, keeping the uncoated cutting edges clear of the jaws to avoid chipping the 90 degree included angle.

When should I replace the uncoated carbide drill mill?

Replace the tool when the cutting edges show visible wear, chipping, or when hole quality degrades during drilling or chamfering operations.
