Sealey SMS01 Drill Bit Sharpener Grinding Attachment

Works fine , saved a few quid on buying drill bits that's for sure.

Made from pot-metal, do not expect engineered/precision made. A bit of a pain to figure out how to use effectively, but once you "get it" easy enough - given that you need to turn the bit through 180degrees for the second edge they didnt figure out an easy solution, but not challenging once you get comfortable - seems to give repeatable results, and re-grinding general bits to a shallower angle makes metal-drilling SO much easier. Would prefer better engineered and would pay a bit more for such, but this does the job.

I have four different types of drill sharpeners and an engineer told me this was the best. And it is. Instructions could be better. I had to consult one of the recent books I bought to set it up correctly and get the correct angle on the drill.

This appeared to be a useful attachment to grind twist drills on a standard bench grinder. It turned out to be totally useless.1. The instructions are pathetic, don't give clear setting up procedure to fit up to bench grinder.2. The illustration is wrong, the name plate must face the user when fitted to the grinder.3. The workmanship / accuracy was very poor, needed a lot of re-working to assemble properly.4. A 3 mm drill can not be fitted without modification to the casting to allow the lip rest to be lowered sufficiently for the drill to sit in the V guide.5. When set up to the grinding wheel for say an 8 mm drill, the set up is incorrect for a 3 mm or a 13 mm drill. The point angle is only correct for the one diameter of drill .6. The "sweep" of the jig results in VERY EXCESSIVE removal of the heel.7. It is difficult to use, following the instructions for grinding the 2nd edge would result in very severe grinding burn.Conclusion: Worse than useless

Very fiddly to use

I bought this for my hubby as a gift he was so pleased with it well made and good quality

OK

Great product
