Great Value and Excellent Performance
This is my review of the 2mm cutting diameter version of this bit, with a flute size of 6mm and 1/4" shank. In other words, it cuts a 2mm minimum width to a maximum depth of 6mm and fits in a router collet suitable for 1/4" shanks. It cost me just under £10 - which is cheap for quality router bits! I bought it to produce a thin, shallow decorative straight cut in MDF and to help cut out alpha-numeric characters from 6mm MDF. This is a quality router bit. Extremely sharp and fits very nicely in my cordless XR Dewalt router. Cutting is effortless with no stalling or scorching of the wood. Cuts are very clean and sharp, with no tearing in MDF. Rotation is spot on - no side to side motion. Supplied in a nice, protective plastic tube-like case. Great value bit which does the job admirably! Hope I've helped :-)

Quality and great value
I’ve bought a number of cutters from Rennie and am very impressed with their performance. Even with cheap router cutters you expect and generally get accuracy but longevity not so much. I’ve given the Rennie cutters plenty to do in a range of manmade and natural materials and I can say they’re as good as the first cut. I can thoroughly recommend these cutters not merely for performance but also value for money compared with what one might think of as premier brands.

Professional router bit with excellent finish.
I wanted to cut some grooves in my router table, for a couple of T-tracks. Tried with the bit that came with my router, but it just smoked a lot and splintered and burnt the wood. I ordered this router bit and it went through the wood like a knife through butter, leaving a beautifully finished groove just the correct width for the T-track. Cannot recommend this highly enough.

It does the job!
It does the job! Only used it a few times so far, but I haven't noticed any loss of sharpness at the moment. Clean cuts and surfacing jobs are my main reasons for the purchase. I'm happy with my choice.

Good cut, good value.
Great product. Very clean cut, haven't used it heavily but seems very durable. Can't imagine it breaking during use. Very good value for the money compared to alternatives on the market.
