The key to Pro-Lok safe bit success is the special tip design. Would you imagine you could drill a 3/8” hole in a piece of hardplate from a Mosler TRTL30 in 38 seconds with a Pro-Lok safe bit?  Would you like to be able to use one safe bit and be able to drill 25 holes in a piece of GSA hardplate in only 7 minutes?  You can now do this and more with the incredible Butter Safe Bits from Pro-Lok.  These Tungsten Carbide “Butter Safe  Bits” feature a special tip design.  The tip uses a unique negative take angle and a shortened chisel edge that increases its effectiveness and reduces the tip failure.  Pro-Lok’s Butter Bits will benefit the security professional who encounters hardplate while drilling safes.
