Premium Boring Tool Holder
High-Rigidity Reducing Sleeve Design for Enhanced Small Boring Stability The “large shank + small inner hole” structure significantly improves overall rigidity compared to directly clamping micro boring bars. It minimizes vibration and tool deflection during small-hole boring, eliminating chatter marks and dimensional errors while improving hole surface finish and machining accuracy.
Precision-Ground Construction with Low-Runout Clamping Both inner and outer surfaces are precision-ground for high coaxiality. Combined with side screw locking, the holder delivers minimal runout, ensuring consistent hole dimensional accuracy and reducing scrap rates. Optional through-coolant versions allow cutting fluid to reach the cutting edge directly, solving chip evacuation and cooling challenges in small holes.
High Versatility for Multi-Equipment Compatibility Standard shank sizes fit most CNC lathe and machining center tool posts/ER holders. With inner hole sizes covering φ3~φ10mm, it works with most micro carbide boring bars on the market, adapting to different small-hole applications without changing tool holders and reducing tool inventory costs.
