My question is , Can this drill will be used for cored forearms? if any cuemaker used this drills for cored please advised me because price is very very cheap and gun drills are more expensive.

That can be used but don't expect very good results. Those don't drill very straight, they create a lot of heat and that short screw on the front will sometimes pull the bit into hardwoods to quickly, splitting them. Those are more for rough cuts in soft woods such as fir, during construction for running wires and such through joists.

I've tried so many different ones I probably bought two gun drills with the money wasted. Use a gun drill or expect problems. Wandering is the biggest problem you'll encounter. The brad point is probably the second best to use but you'll still have to peck drill and move slow to keep the heat down. If your going to use this drill...bore the hole as deep as you can first to get it started as straight as you can.


Dick....I think you have this one confused with an auger bit. They are definitely no good coring...IMO.

See if Hightower has any of his gun drills left. Reasonably priced without the wait of ordering one from the manufacturer.

For what its worth, here's my reasons not to go the cheap route.

Some drills like the one in question are simply made to punch holes not to make deep straight holes. That's why you're hearing all the problems with those that tried alternatives.

Gun Drills are specifically made to drill straight deep holes to a specific diameter.

Believe it or not inexpensive drills are straightened by crude methods such as by hand using drop hammers against a granite surface. It's eye balled till no light is showing through. That's not perfect it's just close and close serves their purpose in life.

I've not seen gun drills manufacturered but I have to assume they're made with already hardened steel then centerless ground after the tips are installed. With the oil holes/air holes peck drilling is reduced or eliminated. As stated the brad drill would require you to peck, if not it would be another cause of wandering plus the heat also mentioned.

Carbide tipped drills should last years in wood and can be easily resharpened or re-tipped. The shank should last generations unless abused.

Sorry I'm not a cue maker, just a tool guy.
