The YUKIWA BT40-NDC20-105 is a drill mill chuck designed for machining centers. It features a BT40 taper shank, a holder length L of 105 mm, and a clamping capacity of φ3.5–20 mm. With the appropriate collet, it can hold straight-shank cutting tools such as drills and end mills for drilling and milling operations.
Part of the YUKIWA NDC series, this holder uses a lock nut and collet to secure the cutting tool. Changing the collet allows different tool shank diameters to be accommodated, providing flexibility when preparing tools for different machining tasks. Compatible components include YCC20 series collets, the NDN20 lock nut, and the FS52 spanner.
When selecting this holder, check the machine spindle interface, tool shank diameter, machining depth, and clearance around the workpiece and fixtures. Clean the taper, collet, and tool shank before assembly, and follow the manufacturer’s clamping instructions. Confirm the supply of collets, spanners, pull studs, and other accessories against the actual order specification.
