Description of 🔩 Roman Carbide DC1919 Forstner Bit 15mm
Hex shanks will not slip and fit 3/8-inch drill chucks. Includes fitted wooden case. Micro-grain carbide stays shaper longer. Hard to find metric sizing.
Я купил это, чтобы заменить свои биты Forstner из быстрорежущей стали, и эти биты Forstner с твердосплавными наконечниками режут намного лучше, чем все биты из быстрорежущей стали, которые я использовал in the past. I also believe they will outlive the HSS bits by a lot.
I have used all the bits and found that the 35mm bit has 3mm run out on my dial indicator which is not good for me. So if you need a 35mm hole you will get a +- 37mm hole not pressed at all
Excellent for the price. Used a 20mm bit to make some small MFT like tables out of 3/4" birch plywood. Stayed sharp. Love the hex shank - no slipping unlike some HSS bits I get from another supplier They hold up much better than HSS Nice wooden cases.
