لقمة حفر رقم 75 (عبوة من 6)

I needed a tiny bit for a small model part and the .021" diameter was exactly right. It went through hard maple without any binding and left a clean hole. Nice to have a set that actually stays sharp for more than one use.

The precision-ground tips on these No. 75 bits bite into brass and plastic without wandering, and they've stayed sharp after drilling through half a dozen small circuit boards.

These No. 75 bits are so tiny I was worried they’d snap, but the high-speed steel has held up through a few plastic and soft metal jobs without dulling. The precision-ground tips start clean without walking, which is exactly what I needed for small pin holes.
