لقمة ثقب تمديد طائرة 12 بوصة، 1/8، 5/32، 3/16، 7/32، 1/4 بوصة، 5 قطع، Drill Hog

Bought these to drill through doubled-up studs where my regular bits barely reached. The M7 molybdenum steel cut cleanly through without wandering, and the 135° point grabbed right away on the 1/4" size. Five sizes in one set for this price is hard to beat.

The M7 molybdenum steel on these is no joke, they chewed through a steel plate without dulling. Having all five sizes in 12" length meant I didn't have to keep swapping bits mid-job.

These 12" bits saved me when I had to drill through a double-stud corner where my regular bits were way too short. The M7 molybdenum steel held a sharp edge through old pine without wandering, and the 135° point started clean on the first try.
