4件式 1/16 英吋螺旋細節套件 – AstraHP 塗層

The AstraHP coating held up beautifully through a full day of intricate engraving on hard maple—no burning or dulling, which surprised me. The up-cut spiral cleared chips effortlessly, and the 1/16″ size let me get into tight corners my other bits couldn't reach. This kit's become my go-to for fine

The 1/16 inch diameter is perfect for the tiny lettering I rout into walnut signs, and the AstraHP coating has held up way better than the bare bits I used before. Four bits in one kit means I'm not stopping mid-project when one gets dull.

Bought these for cutting small inlays in walnut and the 1/16 inch size gets into corners my bigger bits can't touch. The up-cut leaves a cleaner edge than I expected on the top face. Four bits for the price of what I used to pay for two is a nice bonus.
