Bosch Mini X-Line Pro High-speed Steel Cobalt Metal Drill Bit Set, 7-piece, 2–10 mm

The Bosch Mini X-Line Pro HSS-Co Metal Drill Bit Set is a 7-piece collection of high-speed steel spiral bits for metalworking. It is designed for boring holes through dense industrial and structural materials. Operators can use the set on alloyed and unalloyed steel, stainless steel, cast iron, cast steel, and acid- and heat-resistant metals. The bits fit both standard handheld power drills and stationary workshop drill presses. The set is a dependable choice for regular workshop repairs and targeted metalwork projects.

A standard cylindrical shank ensures secure retention in conventional three-jaw chucks. This mounting prevents slippage during high-torque applications and keeps the bit aligned as it enters the metal. The straight shank also suits standard chucks that lack modern hex receivers. Weighing 80 grams in total, the complete package adds minimal bulk to a tool bag or storage drawer. The straightforward shank mechanics transfer rotational force directly from the motor to the workpiece.

• Contains 2, 3, 4, 5, 6, 8, and 10 mm diameters to match common hardware dimensions.
• Blended with a 5% cobalt alloy to maintain structural integrity at high drilling temperatures.
• 135° split-point angle prevents wandering and allows for immediate hole starts on smooth steel.
• Two cutting edges per bit for steady, balanced material removal.
• Supplied in a dedicated carrying case that keeps the bits organised and protects them in transit.
