„Eternal Tools“ apžvalgos

Thanks for your great review! We'd love to have them made in larger sizes as well but due to the small shank and with the ability to use them in pendant drills and hobby rotary tools, the larger we go with drill size diameter, the more wobble we get when drilling.
If you do need a larger size core drill you can always use our standard diamond core drills in a regular household drill.

Hi Rupert, the small diamond twist drills are the correct drill bits to use on window glass, great for de-misting double glazing, that sort of thing.
We will email you directly with regards to the drill bits you bought, which are not intended for use on window glass.

Thanks for the great review on the 8mm arbor for Boley and Boley Leinen watchmakers lathe,! It's great to hear it worked out well for you and that you're pleased with the quality. thanks for taking the time to review our products and for your continued custom.

The carbide micro drill bits look as though they're up to their usual great work - thanks for sending in your examples of the brass plates you've drilled with them John, nice clean holes, brilliant.
Yes, you're right, these drill bits need to be run at very high speeds. There's a table in the technical tab on the product page with cutting speeds etc

These little figures are super! Thanks for sending in the image, we love to see how our tools are being used, and in this case it looks as though the mini rubber silicone polishers are working a treat to give a nice polished finish.
Thanks for the suggestion on the screw mandrel, we take note of all comments from our customers so watch this space and hopefully we can find the perfect mandrel for you in future.
