Star M, High Speed Steel Countersink and Plug Cutter Set

Really well made set. The plugs fit absolutely perfectly, even on a Dewalt countersync drill bit. Only reason I gave it 4 stars is the hex mounting portion seems to be too long so it doesn't lock into my Makita driver collar. I might end up grinding away some of the material at the back to get it to lock properly. All other bit sets from various manufacturers fit the Makita so I am assuming this bit set follows a different standandard. Still I would highly recommend it.

It is great to use and the plugs fit so snug. It is great highly recommend.

I discovered Star M drill bits in Japan some time ago. They give the cleanest cut out of all the drill bits I have used in the past, simply beautiful to use. The Star M plug set which I purchased for a specific job did not disappoint, the plug fit was perfect, so clean! I can’t recommend Star M highly enough.

Very happy with the Star M high speed steel countersink and plug cutter a nice clean cut with the countersink and the plug cutter.The Japanese make some very nice tools. I’ve had very good service from Japanese Tools with all of my purchases and there Star M Super Clean Cut drill bits there isn’t any other drill bit that comes close to them
Highly recommend Japanese Tools for service and the tools they sell

Surprised at how clean both peices cut. Wonderful quality.

Star M, High Speed Steel Countersink and Plug Cutter Se 3mm/9mm I have received the set and I am very pleased with the quality of the product but I have not used them as yet but I will early in the new year and I am sure they are top quality.Norman

I’ve been looking for an accurate, clean plug cutter and countersink set for a while. I actually started to think my old clunker of a drill press was the problem, turns out it was just my drill bits!
These are so clean on hard and soft wood. They work with ease, I highly recommend them.

I already have 20 plug cutters of various sizes and cutting styles.This is because they are all stand alone cutters to which you must match the drill. On my most recent job only one of my 25mm drills was anywhere near a snug fit so I was keen to try your tool.After trying the 9mm set I immediately ordered the 10mm(I would have taken any other sizes if I could!)
These work because 1. They are engineered as a pair so that the plug sits snugly in the hole and
2.the design of the cutting surfaces ensures that both plug and hole have very clean edges.
What to do with a box of useless cutters?
