About drill bits

View:9103/11/2019  

What drill bit is best suited to drill into lead?

Use a brand-new bit for metal mounted on a hand drill (not electric).  Slowly rotate the bit in the lead, which is a "soft" metal.


How do you remove a lawn mower blade?

depends of the brand, generally a 5/8 or 9/16 socket. MAKE SURE YOU REMOVE THE SPARKPLUG


What Is a Step Drill Bit Used For?

A step drill bit is used on metal at a slower speed. The right drill bit makes all the difference between good and bad work. Only a small amount of pressure is needed with an appropriate and sharp bit.


what kind of drill bit in 1mm brass sheet?

I assume I would drill a pilot hole before drilling the size of a hole that is about the size of this '0' (only round instead of oval and a little bigger).  So what kind of drill bit would be best to use?  I have both a Dremel drill and a bigger drill.  The brass sheet being only 1mm maybe any kind would do.
