Twist drill vs brad point drill bit? 

Both twist and brad point drill bits will do a good job for your turning projects, but there are a few reasons you may want to consider giving brad point drill bits a try:

• A brad point drill bit is designed to be used on wood, whereas a twist drill is a general purpose drill bit.
• The pinpoint tip of a brad point drill makes centering on your blank more accurate. 
• Brad point drills cut with precision for a neat, clean drill hole. 
• The chance of blowout is decreased because the point exits the blank first.
