This ultimate in extreme-performance "Lightning Series" 1/8" drill bit & 1/4" drill bit for CNC routers cannot be matched in performance when it comes to drilling holes fast and clean (Includes a FREE 1/8" down-cutting endmill when you order this set!)

Made of solid carbide, and a custom grind at the drilling point, these drills are your game-changers when it comes to drilling on a CNC router because they are designed specifically for CNC routers.

Both the 1/8" drill bit and 1/4" drill bit are designed to handle the high spindle speeds of CNC router woodworking projects without overheating AND these bits eliminate peck drilling!

When it comes to CNC drill bits, these aren't called Lightning Bits for nothing. Both the 1/4" and 1/8" drill bits for CNC routers are made for CNC router owners who are tired of waiting for the long peck drilling cycles and want to get their holes drilled hyper-fast while leaving super-clean cut lines at the entry point.

The "Lightning" series 1/8" drill bot & 1/4" drill bits for CNC routers are designed to get chips out of the way fast, allowing for deep plunges without retract cycles.

Run the 1/4" CNC drill bit at 10,000 RPM at 50 inches per minute, and each hole is complete in less than 2 seconds.

Same with the 1/8" drill bit, except it's even faster. Turn it at 17,000 RPM at 60 inches per minute and each hole is done in 1 second (at 3/4" deep). Compare that to peck drilling with endmills or standard drill bits, which can take up to a minute per hole.

Made for cabinet making and other projects where efficiency and long tool life are important. Making cribbage boards? You'll never go back to peck drilling with high-speed steel bits or endmills again.

If you are planning on designing and making a DIY cribbage board game, you want the holes to be perfectly positioned. Whether you are making it by hand with a drilling jig or on a CNC router, standard drill bits can lead to 'walking'. Meaning the drill bit deflected as it entered the hole. The true point of the drill, with the rigidity of carbide., prevents this from happening.

And speaking of cribbage boards, you get FREE Cribbage board files with this set.

Great bits

The order was promptly delivered. I have used the bits for a couple of projects. They drilled the holes very fast and the holes fit the brass dowels perfectly. I would recommend the IDC drills.
