Why Micro Tools Break — And How to Prevent It

If you’re running micro end mills, drills, or reamers — this is worth your time.

Miniature tools don’t behave like standard cutters.
Different chip loads. Different rigidity. Different strategy.

In this excellent video, the “Cutting Tool Counselor,” Don Grandt, explains:

• Why micro tools break
• What causes premature failure
• How to adjust feeds & speeds properly
• Practical tips for success in miniature machining

Micromachining is its own discipline — and understanding tooling is critical.

Whether you’re cutting microfluidic channels, precision optics, or biomedical components, this is solid advice.

Today’s stop: MIT Department of Biological Engineering
We’re on-site installing a Minitech 5-Axis CNC Mill/GX with ATC at MIT’s Biological Engineering Lab.

Researchers are utilizing this system to manufacture microfluidic devices that support the development of Organ-on-a-Chip technologies, advancing commercial applications in drug discovery and pharmacokinetics.

Proud to see Minitech precision powering groundbreaking research at MIT.
