4.0 MM DOBBELT STUBBOR SLEBNE HSS STD (10 stk pak)

Thürmer Tools Double-Ended Stub Drill, Ground HSS is a professional precision drill engineered for accurate drilling with maximum rigidity and control. The short, double-ended design provides high stability and reduced vibration, improving guidance and hole accuracy—especially in demanding or repetitive drilling operations. Manufactured from high-speed steel (HSS) and precision ground for consistent dimensions and smooth cutting performance. The 118° point geometry ensures controlled entry and efficient cutting. From 3.0 mm, the drill features a split point for rapid centering and immediate bite, reducing walking on the workpiece, minimizing the need for pre-drilling, and improving accuracy. The ground flutes support efficient chip evacuation and stable cutting, producing clean, low-burr holes and extended tool life.
