Part of my living is made from woodworking these days and been doing it for a while now. It has taken me several years to accept the fact that not all bits are equal for removing wood chips from a bored hole.
Some bits remove chips from the hole substantially more effectively then others. The sharpness of the tip has something to do with that but just recently I lost or had stolen a box of original Craftsman drill bits passed on to me by my father, that were in mint condition. I noticed that the bits had an outstanding ability to hold and remove cut/drilled wood because of the design of the helical fluting up the shaft of the bit. The fluting had a more circular cross section in it allowing the bit to better grasp and remove the wood out the flutes of the bit itself. Makes for some frustrating cleanup of the bit after the hole is drilled and perhaps that works against you sanitation wise for the next hole drilled but the design removes chips from the hole more effectively.
Additionally a dull bit or bit with dull side blades is more likely to rip wood rather then cut it as it spins through the hole, causing bigger chips that are more difficult to slide out the helical fluting of any drill bit whether it be a well designed flute or not.
Finding that old craftsman box of bits is one of my biggest problems these days. My girlfriend bought me six locator beacons for Christmas. But so far I only have locator beacons on my phone and keys. The old Craftsman drill box is next. If I ever find it.
I am not sure how the expensive Leader "tapping bit" works as I have been too cheap to buy one but the extra cost and design may well be worth it if chips in the hole are the problem of your day.
