Drill diameter is adjusted by moving X-axis. The moving direction of the X-axis depends on the position of the toolholder. 2. In case of making the hole diameter larger, slide the tool along the X-axis toward the outer insert side. (Fig. 2, Fig. 3) For making the hole diameter smaller, slide the tool along the X-axis in the opposite direction. (This movement of the axis is called “Offset”) However, be sure not to make the hole diameter smaller than the drill diameter by 0.2mm or more. Otherwise, the toolholder will interfere with the drilled hole. (Fig. 4) e.g.) In case of using ø20 drill, the hole diameter must not be smaller than 19.8mm. 2. Offset Limit of the Drill Diameter For the maximum limit of the drill diameter, refer to “Max. Offset (Radial)” in the Toolholder Dimensions table. (The figure in the table shows how much it is possible the offset the drill in the radial direction.) e.g.) In case of using ø20 drill, it is possible to make a hole up to ø21 since “Max. Offset (Radial)” is +0.5mm. Interference Interference SSm maa K llleer r Laarr ggeer r X- of t aaxxisis he m Maac chhinin ee LLar X-a SSm Drill dia. Dia.

Center height of the inner insert When installing inner insert as shown in Fig. 1, it will be set around 0.2mm below the Center of Spindle. (Fig. 5) Center of spindle Center of spindle This is the normal position of the center height and the drill is designed to be handled in this condition. However, in case that the turret of the lathe is out of the center of Spindle, sometimes the inner insert may be set above the center, or excessively below the center. (Fig. 5) Front view of the drill For stable drilling, it is essential to check the Center Height carefully. 2. How to check the center height For checking the center height of the inner insert, see the core which remains Core (About 0.5mm Core(about indiameter) 0.5mm in diameter) at the center of the end face of the drilled hole. (Fig. 6) If the center height is in the normal position, a core about 0.5mm in diameter, will remain after machining. In the following cases, it is necessary to adjust the center height. · No core remains · Core diameter is more than 1mm * The drilled hole for verification purposes needs to be machined at approximately 10mm in depth and at a feed rate of 0.1mm/rev or lower.
