c

 I have 8 holes in it; 3, 4, 5, 5.5, 6, 6.8, 8, 10. I accidentally made a mistake with my 5 and 5.5 hole, i dont have 5.5 but they're both 5. I also use Micrometer and Vernier to measure my drill bit, and i am more comfortable using Micrometer, i find Micrometer hard because i dont know where can i see the size.


Micrometer has a Ratchet, Lock knot, Sleeve Thimble, Knurled Grip, C Frame , Spindle, Anvil and etc.

Vernier Caliper has a Main scale, Depth Rod, Thumb screw, Vernier scale, Lower Jaws for outside measurement, Upper jaws for inside measurement, and Etc.

Press Drill has Chuck, Adjustable table, Safety guard, Pilot Wheel, Column and Etc.
I use this Drill to make holes
