Hougen11085 RotaCut Hole Cutter Master Kit - Fractional 21 Piece, 1/4 to 3/4" Cutter Diameter, 1/4" Cutting Depth

Fast cutting, clean cuts, long lasting

Modified the Hougen 02608 adapter by enlarging the 1/4" hole to 0.397' and altered to 3/8" hex.Enlarged the hardened adapter hole by using carbide drill bits from 0.26563 (17/64") to 0.397 (17 drill bits) then used a 3/8" hex push broach.Replaced the existing set screw to a 5/16-24 x 5/32" long.Hougen weldon 3/4" shank is exactly 0.7493" O.D.

Haven't had this product for very long, but I have cut 150 holes with the 5/8 inch cutter with no issues. The last hole is as nice as the first and the plug ejector is a time saver.

There is nothing like a Hougen cutter. Cuts through steel 10x faster and much cleaner than any twist drill. I have a Hougen magnetic drill and annular cutters for heavy duty projects, but I was incredibly pleased with how well these worked on a Dewalt 20v drill. Use cutting oil, heavy down pressure (until you’re close to break thru) and low drill speed for best effect and longest cutter life.Good seller. Kit arrived quickly and in perfect condition.

These hole cutters work great. They are made well and make cutting, many holes in 16g mild steel a breeze.

RotaCut cutters make clean cuts in sheet aluminum, just the thing for manually laying out and cutting instrument panels using a drill press.

You can cut deeper if your center hole is drilled with an 1/8” drill bit all the through. This kit will last for 100’s of holes with oil, and it still works with broken teeth .
