Emma ★★★★★

These M2.5x8 screws fit the CCMT insert holders perfectly, and the T-8 Torx drive makes installation snug without stripping. Exactly what my 1779 boring bar needed to lock the inserts down tight.

Joshua J. ★★★★★

Exactly the right T-8 Torx head for that 1779 bar, and the M2.5x8 length seats the CCMT insert snug without any wobble. I appreciate that the listing warns you to double-check your tool's insert type—saved me from a misfit.

Natalie F. ★★★★★

Threads went in clean on the 1779 boring bar and the M2.5x8 length is spot on for holding the CCMT insert without bottoming out. The included T-8 Torx wrench was a nice touch since mine had wandered off.
