Left Hand Drill Bit
Yes, there really are left hand drill bits.
They are usually special order. You wouldn't see them in the normal hardware sections of chain stores.
They are used in the machine shops to get difficult bolts out.
Most of the time the bolt will heat up some from drilling it.
The heat helps it turn loose and then the left twisting pressure from drilling would turn it right out.
You would find them some place like McMaster-Carr (or machinist supply stores). 1)

Pilot Point Drill Bit
These bits have a built in 'center bore' on the end.
It cuts center first and the fluted cutter comes in to cut the primary hole.
This helps to keep the bit from wandering and keep the hole centered throughout the cut.
Pin Vise
A pin vise is made for holding tiny drill bits.
Some are made to be chucked into a standard drill and others are hand held standalones.
- This is an Albrecht JO30 pin vise for 0-1/8“ diameter bits. The cost is upwards of $250. 3)

Hole Saw
A hole saw is not just used for door knob installation.

Center Punch
A center punch is crucial in helping to ensure a drill bit doesn't wander or walk off when starting a hole.
Manual Type
Standard center punch used with a hammer to spike a dimple in the workpiece.
Automatic Type
An automatic center punch doesn't need a hammer to make a center hole.
This makes it a good alternative on plastics where a spike from a standard punch might crack it.
It's spring loaded. Position it where you want a center and push it toward the workpiece.
This punch was used to make a tail light mod for broken factory mounting studs 9) |
