Pros
Sweet Tips β Countersinks with 1/4β³ hex shank are for fast drilling. They will not slip in drill chucks. You can easily make deep countersinks by adjusting the countersink depth gauge to allow the countersink to drill deeper into the work surface. Be sure to measure the size of the dowel to ensure the sinker makes the correct size hole. If you have any problem with the item, please contact us first so we can help you.
