will they fit 3/8 chuck?

Yes they would. The drill bits have hexagonal ends that would make them fit. Other than the 1/2", all other drill bits are smaller than 3/8, so that's a given. Only the 1/2 is in question here.

Kaliteli ürün

Kaliteli ürün, ahşap kullanımlarında kayma olmaması için biraz dikkatli olmak gerek. Sadece ahşap kullanıma özel uçlardaki gibi ucunda iğnemsi sabitlemeye yarayan çıkıntı yok.
