Precision Set for Internal Machining
The A-SDQCR/L (107.5°) Set Inside turning holders with cooling holes is designed to meet the demands of professional machining. Manufactured by SMOXH, these boring bars combine a rigid steel shank with effective internal coolant delivery. This setup helps manage heat generation at the cutting edge and supports chip evacuation even in deeper bores. Consisting of both the right-hand (Art. Nr. Right: SM59917) and left-hand (Art. Nr. Left: SM59924) versions, the set provides a versatile and ready-to-use solution for directional turning tasks. Packaging Unit = 1 Pc.

Applications
With a 107.5° approach angle, these tool holders are well-suited for contour turning, profiling, and longitudinal operations within confined internal geometries. Designed to accommodate standard 55° rhombic DC-series inserts, the set is an excellent choice for finishing and medium roughing applications. The direct internal coolant supply is particularly advantageous when machining materials prone to long chips or high thermal loads, facilitating reliable production processes.
Special features
This set stands out by including both right and left-hand boring bars, which can reduce setup times and enhance flexibility on the shop floor. The focused internal coolant stream helps prevent chip jamming inside the bore, thereby protecting the surface finish of the workpiece. Furthermore, the secure screw-clamping mechanism ensures accurate insert positioning and allows for swift indexable insert changes directly on the machine tool.
