Micro 100 Carbide Ball End Mill

This Micro 100 carbide ball end mill has a 0.020 inch milling diameter and a 0.060 inch cutting length. It is an uncoated solid carbide tool intended for precision milling tasks. The cutter suits machinists and engineers working on small features in various materials.

Verify shank compatibility and machine rigidity

Before ordering, confirm that your tool holder or collet accepts the shank diameter of this end mill. Ensure your milling machine or router provides sufficient rigidity for such a small diameter cutter. Check that your workpiece material suits an uncoated carbide geometry without coolant through the tool.

Solid carbide construction for wear resistance

The solid carbide body offers high hardness and wear resistance compared to high-speed steel alternatives. An uncoated surface avoids coating buildup in tight radii during finishing passes. The non-coolant-through design means external coolant or air blast must be directed at the cutting zone for chip evacuation.

Questions about this item

What comes in the box with the Micro 100 BMR-020-2 end mill and do I need to buy a holder separately?

The box contains the uncoated carbide ball end mill with a .020 inch milling diameter and .060 inch cut length. A compatible tool holder or collet must be purchased separately to fit your machine spindle.

Which diameter and cut length version should I choose for fine-detail milling in carbide?

Choose the .020 inch diameter with .060 inch cut length when you need a small-radius ball nose for intricate contours or finishing passes in tight corners.

What does the .020 inch diameter mean for step-over and feed rates on a CNC router?

A .020 inch diameter requires a very small step-over — typically a few thousandths of an inch — and lower feed rates to avoid tool deflection and achieve a smooth surface finish.
