W 单刃带钻头 ZU-0380-3E-W / ZU-0380-3I-W

0.01mm Hole Precision, Backed by a Single Margin

W single margin solid carbide drill, ZU-0380 series. The single margin structure supports the cutting edge as it works, so the drill runs smoothly and puts less load on your spindle. Hole tolerance stays within 0.01mm. Two straight-shank versions: ZU-0380-3E-W (outer cooling) and ZU-0380-3I-W (inner cooling).

  • Single margin support keeps cutting smooth and machine load lower
  • Protection edge on the cutting tip helps stop chipping
  • Passivated edges for better edge strength and steady cutting
  • 3xD, 5xD, 8xD lengths, φ3–20mm

Key Advantages

Built for Reliability in the Field

Each part is engineered and QC'd against the exacting standards your equipment demands.

The single margin backs up the cutting edge during the cut, which keeps the drill steady and reduces load on smaller machines

Hole tolerance is held within 0

01mm, so you spend less time on reaming or sizing afterwards.

A protection edge on the tip takes the impact at breakthrough and helps prevent chipping, especially in interrupted cuts

FAQ

Questions Buyers Often Ask

Should I take the -3E-W or the -3I-W?
It comes down to cooling. The -3E-W is outer cooling and works fine for standard holes on most machines. The -3I-W feeds coolant through the tool, which helps when you go deeper or the material makes long chips that need flushing out. Same body, same single margin design, just different coolant routing.
Can it really hold 0.01mm?
Yes, within 0.01mm, provided the machine, holder and parameters are in good shape. The single margin keeps the drill from wandering, and the passivated edges cut cleanly. If your setup is loose or the spindle has runout, expect the result to drift with it.
What materials does it handle?
Steel and stainless steel are the main ones, and it also works in other machinable metals that need accurate holes. If you are running something unusual, send us the material grade and cutting conditions and we will tell you whether this drill fits or a different grade is a better call.
How fast can you ship?
Standard sizes are usually on the shelf and go out quickly. Non-standard sizes or large quantities typically take 3–4 weeks. Confirm with our sales team before you plan around a date.
Which length should I choose?
3xD for normal holes, 5xD when you need more reach, 8xD for deep holes. From 5xD up, go with inner cooling so chips clear properly and the tool lasts.
Do you provide inspection or samples?
Every drill goes through edge passivation and the protection edge check before packing, and we can send dimensional inspection reports with your order. If you want to test before committing to a bulk order, we support sample runs.
