Somta Stub Drill - HSS-E Parabolic Flute TiAlN COATED - 5.1mm

The Somta Stub Drill in the HSS-E Parabolic Flute TiAlN Coated series, sized at 5.1 mm, is a high-performance drill bit built for demanding metalworking tasks. Crafted from HSS-E for exceptional hardness and heat resistance, it features a TiAlN coating to boost wear life and lubricity. The parabolic flute design enhances chip evacuation, helping maintain cooler cuts and cleaner holes even in tougher materials.

Its stub length provides outstanding rigidity and stability during drilling, reducing deflection and improving hole accuracy. This makes it a dependable choice for engineers, machinists, tradespeople, and hobbyists who need consistent results with minimal effort.

• Parabolic flute design for efficient chip evacuation: Clears chips rapidly to reduce heat buildup, prevent chip recycling on the cutter edge, and support smoother, deeper drilling with stable hole quality.
• TiAlN coating for wear and heat resistance: Delivers longer edge life, lower friction, and better performance in high-temperature or demanding metalworking applications, helping maintain sharpness over more holes.
• Stub-length geometry for rigidity and precision: Provides increased stiffness and reduced vibration, yielding starting accuracy and cleaner, true holes in challenging materials.

Together, these features translate into reliable, repeatable results with fewer tool changes and less downtime. The 5.1 mm Somta Stub Drill is a dependable choice when you need precise holes, consistent finishes, and extended tool life across a range of metals.
