15° カービングライナー – Whiteside SC54 (AstraHPコーティング)

The 15-degree angle on this bit made setting up precise V-grooves effortless, and the AstraHP coating really helped it glide through the wood without any burning. Cut quality is consistently sharp and clean.

I was a little worried the coating would wear quickly, but after several test cuts in oak, the AstraHP finish still looks brand new. Clean, sharp V-grooves every time with zero burning.

I was a bit skeptical about the AstraHP coating at first, but after running it through some hard maple, the bit came out looking new. The cut quality is incredibly clean with no burning, and the 15° angle makes precise grooves easy to control.
