Description
The Somta Stub Drill, HSS-E Parabolic Flute TiAlN Coated, 11.5 mm is a high-performance drill bit built to handle demanding drilling tasks. Crafted from high-speed steel improved with extra hardness (HSS-E), it delivers robust heat resistance and durability for reliable hole creation in a variety of materials. The 11.5 mm diameter combined with a stub length provides exceptional rigidity and stability, helping you achieve precise, true holes from the first bore.
TiAlN coating enhances wear resistance and lubricity, helping the bit stay sharper longer while standing up to higher cutting temperatures. The parabolic flute design promotes efficient chip evacuation, reducing heat buildup and keeping the drill cooler during extended cuts. Together, these features translate into longer tool life and less downtime on busy jobsites or in production environments.
- Rigid stub design for precise holes: The short, stiff form minimizes deflection and vibration, delivering accurate hole location and clean edges even in challenging materials.
- TiAlN-coated HSS-E for longer life: The coating boosts wear resistance and heat tolerance, helping the drill maintain sharpness and extend service life in demanding applications.
- Parabolic flute for efficient chip evacuation: Flutes move chips away quickly, reduce heat buildup, and minimize clogging for smoother drilling and cooler operation.
This combination equips you to complete projects with consistent results, faster throughputs, and fewer tool changes. The Somta Stub Drill is a practical choice for professionals who need reliable performance, straightforward setup, and holes that meet high-quality standards without compromise.
