kaam ho gaya mast
bhai sahi cheez hai, steel pe direct chalao bina slip hue bina walk kiye. black and bronze oxide coating ki wajah se heat bhi kam pakadta hai. packaging thodi ched-chad hui aayi thi par andar bits bilkul safe the aur ekdum sharp nikle. 6-pack hone ka yeh fayda hai ki ek kharab ho toh doosra ready hai.

good durable drill bits
Ordered this 6-pack for our workshop setup since we do heavy-duty fabrication work regularly. The 135-degree split point is really helpful because it starts drilling immediately on contact without sliding around. Only giving four stars because one of the boxes inside was slightly squished during transit, but the bits themselves are undamaged and working fine.
