Router Bit Straight 1/4" : 12 x 20mm is rated 4.3 out of 5 by 125.
Rated 5 out of 5 by from Good finish from a budget cutter. Much better finish than you would expect from a cutter at this price. Have used other premium brand cutters but not necessarily achieved a similar level of finish with them.

Rated 1 out of 5 by from It’s cheap for a reason Bought 3 of these to do shelf pin holes in a cabinet. Did a test run of 10 plunge cuts 7mm deep in MDF. The holes were at least .5mm oversize so the pins just fell out and the bit overheated and left burn marks on the wood. All three went in bin.

Rated 4 out of 5 by from Did the job at a reasonable price Reasonable router bit. Didn't seem quite as sharp or precise as the 6mm Trend equivalent, but a lot cheaper

Rated 4 out of 5 by from 4mm Cheap Router bits Bought a few of these for routing small discs in 3mm thick plywood. I bought a few in case they broke, but only used one which didn't, probably because i used two passes. They did the job anyway, and were very cheap.
