エンドミル（ミニチュア） 2フルート 両端HSS 個別サイズ

The medium-high helix on these miniature bits gives a noticeably cleaner cut in aluminum than standard end mills I've tried. Double-ended design means I get twice the life from each tool, perfect for small engraving jobs.

I’ve been using these double-ended bits for pocketing in aluminum and the cut is impressively smooth. The medium-high helix really helps with chip evacuation in smaller slots.

For tiny engraving work in brass, the medium-high helix makes a real difference in how clean the cut comes out—no chatter even at shallow depths. These double-ended ones last twice as long between swaps, which is exactly what I need for quick pocketing jobs.
