Compatible with handheld drills and drill presses for precise holes.

## Long description

Spiral HSS drill bit by Bosch with a 12 mm diameter and 151 mm overall length, featuring a titanium nitride (TiN) coating. The tool is engineered for drilling into a variety of metal types and general-purpose workshop tasks. A high-speed steel (HSS) core delivers hardness and heat resistance during continuous use, while the TiN coating reduces friction and enhances wear resistance to extend the service life of the bit. The fluted spiral design supports efficient chip removal and more accurate hole drilling when used in handheld drills or drill presses.
Advantages
The 12 mm HSS spiral geometry provides reliable concentricity and clean hole walls in metalworking and mixed-material applications. TiN coating lowers cutting temperature and friction, which helps maintain edge sharpness and prolongs tool life under moderate to heavy use. The 151 mm overall length gives extra reach for deeper holes and flexible positioning, and the hardened HSS core resists deformation during high-speed drilling.
Suitable for
Drilling through mild steel, stainless steel, and non-ferrous metals
General workshop and maintenance tasks requiring a 12 mm hole
Use in handheld electric drills and bench drill presses
Fabrication, installation, and repair jobs in mechanical and construction workshops
Key specifications
Diameter: 12 mm
Overall length: 151 mm
Material: high-speed steel (HSS)
Coating: titanium nitride (TiN)
Flute type: spiral for efficient chip evacuation
How to use
Secure the drill bit in the chuck of a handheld drill or drill press, ensuring proper centring and tight clamping. Select an appropriate spindle speed and feed rate for the material being drilled — lower speeds for stainless steel, medium to higher speeds for mild steel and non-ferrous metals. Apply steady pressure and allow the bit to cut without excessive force; retract occasionally to clear chips when making deep holes. Use a cutting fluid or lubricant for harder metals to reduce heat and improve finish.
Usage recommendations
For best results, match drilling speed and feed to the workpiece material, use cutting lubricant when drilling stainless or hardened steels, and inspect the TiN coating for wear periodically to maintain performance and prolong bit life.
