OSG Holders
A holder is a tool for installing the insert (head) of an exchangeable head drill. There are different types of products of which dimensions including overall lengths, shank diameters, and processing diameters are different, and the size of a head that can be attached also varies depending on the type. Also note that heads to be installed of some manufacturers have no compatibility and some tools require a dedicated key for attachment and detachment. Select a holder size according to the processing diameter with consideration for whether deep hole drilling is necessary. The advantage of using a replaceable head drill for cutting is that a head that matches the dimensions of the machine is attached and only the head can be replaced when the blade tip is worn. In some cases, multiple tips can be used with only one holder body. No head is not included in a holder and you need to purchase a head that matches the holder separately to use it.
